Although only about 10 percent of the 2,750 known termite species have been reported as pests, many of these cause severe and extremely costly damage. The process of worker termites feeding other nestmates is known as trophallaxis. [157][182] Despite this, some termites and ants can coexist peacefully. These long-lived queens have a significantly lower level of oxidative damage, including oxidative DNA damage, than workers, soldiers and nymphs. When the swarming termites leave the nest, the nymph termites seal the holes. Coptotermes formosanus, widely distributed in Japan, Taiwan, and South China, has been introduced into Sri Lanka (Ceylon), the Pacific islands, South Africa, East Africa, Hawaii, California, and the southern United States. [42], Termites are usually small, measuring between 4 to 15 millimetres (0.16 to 0.59 in) in length. [221][222] Termite mounds are the main sources of soil consumption (geophagy) in many countries including Kenya, Tanzania, Zambia, Zimbabwe and South Africa. [110] Tetramorium uelense is a specialised predator species that feeds on small termites. [145], Termites can distinguish nestmates and non-nestmates through chemical communication and gut symbionts: chemicals consisting of hydrocarbons released from the cuticle allow the recognition of alien termite species. [71], The life cycle of a termite begins with an egg, but is different from that of a bee or ant in that it goes through a developmental process called incomplete metamorphosis, with egg, nymph and adult stages. This material disrupts normal formation of the exoskeleton (cuticle) of molting workers (the only caste capable of molting), resulting in death of the workers and, eventually, the rest of the colony. [47] Each segment contains a pair of legs. Termites Often mistaken as white ants, termites do differ from ants in terms of how they act and what they look like. Since they feed on wood nonstop, a termite For example, though they might block each other's passages, colonies of Macrotermes bellicosus and Macrotermes subhyalinus are not always aggressive towards each other. [200] Mounds located in areas with torrential and continuous rainfall are at risk of mound erosion due to their clay-rich construction. Several hundred species are economically significant as pests that can cause serious damage to buildings, crops, or plantation forests. [62], Termites are known to carry pollen and regularly visit flowers,[188] so are regarded as potential pollinators for a number of flowering plants. Another method is to place insecticide into small holes drilled into galleries of infested wood. [41] There are three ecological groups of termites: dampwood, drywood and subterranean. Termites occur also in the Cape region of South Africa, Australia, Tasmania, and New Zealand. [234] These robots work independently and can move by themselves on a tracked grid, capable of climbing and lifting up bricks. Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are the sister group to wood eating cockroaches of the genus Cryptocercus. [207], Cathedral mounds in the Northern Territory, Australia, Mounds of "compass" or "magnetic" termites (Amitermes) oriented north–south, thereby avoiding mid-day heat, Termites in a mound, Analamazoatra Reserve, Madagascar, Termites construct shelter tubes, also known as earthen tubes or mud tubes, that start from the ground. [40] In Asia, there are 435 species of termites, which are mainly distributed in China. In many parts of Africa, the alates are an important factor in the diets of native populations. Termites are infected by viruses including Entomopoxvirinae and the Nuclear Polyhedrosis Virus. Within China, termite species are restricted to mild tropical and subtropical habitats south of the Yangtze River. What do Drywood Termites Look Like? [201], Some species build complex nests called polycalic nests; this habitat is called polycalism. Termite droppings or commonly known as frass is one of the common signs of termite infestation in your house. [146] In one species, Nasutitermes costalis, there are three phases in a foraging expedition: first, soldiers scout an area. Lateral ocelli, however, are not found in all termites, absent in the families Hodotermitidae, Termopsidae, and Archotermopsidae. [61][62] Fontanelles, simple holes in the forehead that exude defensive secretions, are a feature of the family Rhinotermitidae. [115][116][117] Other predators include aardvarks, aardwolves, anteaters, bats, bears, bilbies, many birds, echidnas, foxes, galagos, numbats, mice and pangolins. In the Far East Reticulitermes speratus ranges as far north as South Korea, Peking, and northern Japan. These supplementary reproductives only mature into primary reproductives upon the death of a king or queen, or when the primary reproductives are separated from the colony. If it was a female, the body length would be far greater than 25 millimetres when mature. Nests and mounds protect the termites' soft bodies against desiccation, light, pathogens and parasites, as well as providing a fortification against predators. [209] Shelter tubes also provide high humidity and darkness and allow workers to collect food sources that cannot be accessed in any other way. These fights can cause mortality on both sides and, in some cases, the gain or loss of territory. [104][105] Molecular evidence suggests that the family Macrotermitinae developed agriculture about 31 million years ago. For example, Megaponera is a strictly termite-eating (termitophagous) genus that perform raiding activities, some lasting several hours. Specific structures or other objects such as pellets of soil or pillars cause termites to start building. Dry-wood termites nest in the wood on which they feed and do not invade a structure from the soil. Termite monitors made of wood or cellulose adjacent to a structure may also provide indication of termite foraging activity where it will be in conflict with humans. Thermites have diverse compositions. Nuptial flight time varies in each species. Cryptotermes brevis, the most widely introduced invasive termite species in the world, has been introduced to all the islands in the West Indies and to Australia. Instead, like juveniles, they are fed by workers. Originally living in the rainforest, fungus farming allowed them to colonise the African savannah and other new environments, eventually expanding into Asia. [81] The abdomen increases the queen's body length to several times more than before mating and reduces her ability to move freely; attendant workers provide assistance. A termite nest can be considered as being composed of two parts, the inanimate and the animate. Termites are found on all continents except Antarctica. Termite workers, by comparison, are transparent, light or creamy white in color, and they avoid light. [65] A wide variety of monoterpene hydrocarbon solvents have been identified in the liquids that nasutes secrete. The diversity of termite species is low in North America and Europe (10 species known in Europe and 50 in North America), but is high in South America, where over 400 species are known. Winged, reproductive termites are frequently mistaken for flying ants, but are smaller than ants and have straight, rather than bent, antennae. Males (drones) are haploid and develop from unfertilised eggs, while females (both workers and the queen) are diploid and develop from fertilised eggs. Termites are consumed in many regions globally, but this practice has only become popular in developed nations in recent years. [54], Unlike in ants, the hind-wings and fore-wings are of equal length. Termites that cause damage to Australian homes are subterranean termites. [154] Suicide cramming is known in Coptotermes formosanus. [58][61] Among certain termites, soldiers may use their globular (phragmotic) heads to block their narrow tunnels. Termite Facts for Kids. These Nasutitermes nests are mainly composed of partially biodegraded wood material from the stems and branches of mangrove trees, namely, Rhizophora mangle (red mangrove), Avicennia germinans (black mangrove) and Laguncularia racemose (white mangrove). Long Island is the most populated island in any US state. Subterranean termites are small, soft bodied insects that build large nests in soil or trees and have underground tunnels that can reach up to 100 metres away from the nest. Mounds may also provide shelter and warmth to birds, lizards, snakes and scorpions. These swarms attract a wide variety of predators. About 3,106 species are currently described, with a few hundred more left to be described. [221], In addition to Africa, termites are consumed in local or tribal areas in Asia and North and South America. [210], Drywood termites thrive in warm climates, and human activities can enable them to invade homes since they can be transported through contaminated goods, containers and ships. [56], Worker termites undertake the most labour within the colony, being responsible for foraging, food storage, and brood and nest maintenance. [185][186] Iridomyrmex also inhabits termite mounds although no evidence for any kind of relationship (other than a predatory one) is known. Termite baits are poison-filled traps placed strategically around your home’s perimeter. [9], Termites were formerly placed in the order Isoptera. The termite adds these objects onto existing structures, and such behaviour encourages building behaviour in other workers. [72] Nymphs resemble small adults, and go through a series of moults as they grow. Termites and the ecosystem must go together, even if the latter has started to become mainly artificial. Preventive measures include the use of chemically treated wood in building construction and the use of paint or other durable finish to seal cracks in wood surfaces. The most common traditional control used around a structure is to flood a shallow trench with an insecticide and cover it with soil. [83], Termites going through incomplete metamorphosis on the path to becoming alates form a subcaste in certain species of termite, functioning as potential supplementary reproductives. [49] The number of tibial spurs on an individual's leg varies. A trail can be identified by the faecal deposits or runways that are covered by objects. † Archeorhinotermitidae [184], 54 species of ants are known to inhabit Nasutitermes mounds, both occupied and abandoned ones. [187] Some invertebrate organisms such as beetles, caterpillars, flies and millipedes are termitophiles and dwell inside termite colonies (they are unable to survive independently). These small brown balls, known as "termite balls", rarely kill the eggs, and in some cases the workers tend to them. [214] Some termites are considered invasive species. [197] Species in the subfamily Apicotermitinae are good examples of subterranean nest builders, as they only dwell inside tunnels. [227], Termites can be major agricultural pests, particularly in East Africa and North Asia, where crop losses can be severe (3–100% in crop loss in Africa). [231], The development of autonomous robots capable of constructing intricate structures without human assistance has been inspired by the complex mounds that termites build. It is assumed that more than 90 percent of dry wood in the semiarid savannah ecosystems of Africa and Asia are reprocessed by these termites. [39] Of the 3,000 termite species currently classified, 1,000 are found in Africa, where mounds are extremely abundant in certain regions. The queen only lays 10–20 eggs in the very early stages of the colony, but lays as many as 1,000 a day when the colony is several years old. [220] These insects are particularly important in impoverished countries where malnutrition is common, as the protein from termites can help improve the human diet. The animate is all of the termites living inside the colony, and the inanimate part is the structure itself, which is constructed by the termites. Updates? Termites can also damage laminate flooring and even skirting boards. Subterranean termites prefer softwoods, but may invade most species of wood. Though harder to acquire, queens are regarded as a delicacy. [62] As a result, certain beetles and flies have evolved with their hosts. Coeditor of. [221], Alates are collected when the rainy season begins. the age of the carcass). Wear pattern analysis of bone tools used by the early hominin Paranthropus robustus suggests that they used these tools to dig into termite mounds. Termite antennae have a number of functions such as the sensing of touch, taste, odours (including pheromones), heat and vibration. Evolution, paleontology, and classification, https://www.britannica.com/animal/termite, termite - Children's Encyclopedia (Ages 8-11), termite - Student Encyclopedia (Ages 11 and up), Learn how termites use salivary secretions to cement debris to decaying wood nests in their rainforest habitat. The three basic segments of a termite antenna include a scape, a pedicel (typically shorter than the scape), and the flagellum (all segments beyond the scape and pedicel). Mastotermitidae Appearance. [217] The goal of termite control is to keep structures and susceptible ornamental plants free from termites. termite holes. When they do, they excavate a chamber big enough for both, close up the entrance and proceed to mate. When termites feed on the paper, they carry the remains to their colonies and thus continue feeding on it thus complete destruction. [196] A nest has many functions such as providing a protected living space and providing shelter against predators. Our editors will review what you’ve submitted and determine whether to revise the article. [15][16] Termites and Cryptocercus share similar morphological and social features: for example, most cockroaches do not exhibit social characteristics, but Cryptocercus takes care of its young and exhibits other social behaviour such as trophallaxis and allogrooming. [11] In 2008 DNA analysis from 16S rRNA sequences[12] supported the position of termites being nested within the evolutionary tree containing the order Blattodea, which included the cockroaches. [10] In the 1960s additional evidence supporting that hypothesis emerged when F. A. McKittrick noted similar morphological characteristics between some termites and Cryptocercus nymphs. [144] Foraging workers use semiochemicals to communicate with each other,[145] and workers who begin to forage outside of their nest release trail pheromones from their sternal glands. [50] There are ten tergites, of which nine are wide and one is elongated. [6] "Termite" derives from the Latin and Late Latin word termes ("woodworm, white ant"), altered by the influence of Latin terere ("to rub, wear, erode") from the earlier word tarmes. In the second phase, workers appear in large numbers at the site. All that damage because termites love wood and they’ll work their way up from your home’s foundation.This could lead to deadly structural damage. [92] Termites rely primarily upon symbiotic protozoa (metamonads) and other microbes such as flagellate protists in their guts to digest the cellulose for them, allowing them to absorb the end products for their own use. However, Mastotermitidae termites have multiflagellate sperm with limited motility. [25] The oldest termite nest discovered is believed to be from the Upper Cretaceous in West Texas, where the oldest known faecal pellets were also discovered. Some species, such as the West Indian drywood termite (Cryptotermes brevis), are regarded as invasive species. They are regarded as pleasant in taste, having a nut-like flavour after they are cooked. A damp and wet … Oil is not required as their bodies usually contain sufficient amounts of oil. Termiticide also works by spreading like a virus. [55] Studies show that in comparison to larger termites, smaller termites cannot fly long distances. When they find a food source, they communicate to other soldiers and a small force of workers starts to emerge. † Termopsidae[2] [141][142], Because the worker and soldier castes lack wings and thus never fly, and the reproductives use their wings for just a brief amount of time, termites predominantly rely upon their legs to move about. It is unknown whether the termite was female or male. [47] The mouth parts contain a maxillae, a labium, and a set of mandibles. They maintain a "garden" of specialised fungi of genus Termitomyces, which are nourished by the excrement of the insects. [59][100] Judging from closely related bacterial species, it is strongly presumed that the termites' and cockroach's gut microbiota derives from their dictyopteran ancestors. Termites are winged insects that feed on dead and decaying plant material. Not all nests are visible, as many nests in tropical forests are located underground. They have developed a gland that secrete a substance that attracts the workers by licking them. Termites are less likely to be attacked by parasites than bees, wasps and ants, as they are usually well protected in their mounds. [62] Additionally, an alarmed termite bumps into other termites which causes them to be alarmed and to leave pheromone trails to the disturbed area, which is also a way to recruit extra workers. Meanwhile, the higher termites consume a wide variety of materials, including faeces, humus, grass, leaves and roots. [241] Abandoned mounds are viewed as structures created by spirits, believing a local guardian dwells within the mound; this is known as Keramat and Datok Kong. [91] Termites are considered to be a major source (11%) of atmospheric methane, one of the prime greenhouse gases, produced from the breakdown of cellulose. [194] Nests can be broadly separated into three main categories: subterranean (completely below ground), epigeal (protruding above the soil surface), and arboreal (built above ground, but always connected to the ground via shelter tubes). [87] The form of parthenogenesis likely employed maintains heterozygosity in the passage of the genome from mother to daughter, thus avoiding inbreeding depression.

Lateral ocelli, however, are not found in all termites, absent in the families Hodotermitidae, Termopsidae, and Archotermopsidae. [61][62] Fontanelles, simple holes in the forehead that exude defensive secretions, are a feature of the family Rhinotermitidae. [115][116][117] Other predators include aardvarks, aardwolves, anteaters, bats, bears, bilbies, many birds, echidnas, foxes, galagos, numbats, mice and pangolins. In the Far East Reticulitermes speratus ranges as far north as South Korea, Peking, and northern Japan. These supplementary reproductives only mature into primary reproductives upon the death of a king or queen, or when the primary reproductives are separated from the colony.

[81] The abdomen increases the queen's body length to several times more than before mating and reduces her ability to move freely; attendant workers provide assistance. A termite nest can be considered as being composed of two parts, the inanimate and the animate. Termites are found on all continents except Antarctica. Termite workers, by comparison, are transparent, light or creamy white in color, and they avoid light. [65] A wide variety of monoterpene hydrocarbon solvents have been identified in the liquids that nasutes secrete. The diversity of termite species is low in North America and Europe (10 species known in Europe and 50 in North America), but is high in South America, where over 400 species are known. Winged, reproductive termites are frequently mistaken for flying ants, but are smaller than ants and have straight, rather than bent, antennae. Males (drones) are haploid and develop from unfertilised eggs, while females (both workers and the queen) are diploid and develop from fertilised eggs. Termites are consumed in many regions globally, but this practice has only become popular in developed nations in recent years. [54], Unlike in ants, the hind-wings and fore-wings are of equal length. Termites that cause damage to Australian homes are subterranean termites. [154] Suicide cramming is known in Coptotermes formosanus. [58][61] Among certain termites, soldiers may use their globular (phragmotic) heads to block their narrow tunnels. Termite Facts for Kids. These Nasutitermes nests are mainly composed of partially biodegraded wood material from the stems and branches of mangrove trees, namely, Rhizophora mangle (red mangrove), Avicennia germinans (black mangrove) and Laguncularia racemose (white mangrove). Long Island is the most populated island in any US state. Subterranean termites are small, soft bodied insects that build large nests in soil or trees and have underground tunnels that can reach up to 100 metres away from the nest. Mounds may also provide shelter and warmth to birds, lizards, snakes and scorpions. These swarms attract a wide variety of predators. About 3,106 species are currently described, with a few hundred more left to be described. [221], In addition to Africa, termites are consumed in local or tribal areas in Asia and North and South America. [210], Drywood termites thrive in warm climates, and human activities can enable them to invade homes since they can be transported through contaminated goods, containers and ships. [56], Worker termites undertake the most labour within the colony, being responsible for foraging, food storage, and brood and nest maintenance. [185][186] Iridomyrmex also inhabits termite mounds although no evidence for any kind of relationship (other than a predatory one) is known. Termite baits are poison-filled traps placed strategically around your home’s perimeter. [9], Termites were formerly placed in the order Isoptera. The termite adds these objects onto existing structures, and such behaviour encourages building behaviour in other workers. [72] Nymphs resemble small adults, and go through a series of moults as they grow. Termites and the ecosystem must go together, even if the latter has started to become mainly artificial. Preventive measures include the use of chemically treated wood in building construction and the use of paint or other durable finish to seal cracks in wood surfaces. The most common traditional control used around a structure is to flood a shallow trench with an insecticide and cover it with soil. [83], Termites going through incomplete metamorphosis on the path to becoming alates form a subcaste in certain species of termite, functioning as potential supplementary reproductives. [49] The number of tibial spurs on an individual's leg varies. A trail can be identified by the faecal deposits or runways that are covered by objects. † Archeorhinotermitidae [184], 54 species of ants are known to inhabit Nasutitermes mounds, both occupied and abandoned ones. [187] Some invertebrate organisms such as beetles, caterpillars, flies and millipedes are termitophiles and dwell inside termite colonies (they are unable to survive independently). These small brown balls, known as "termite balls", rarely kill the eggs, and in some cases the workers tend to them. [214] Some termites are considered invasive species. [197] Species in the subfamily Apicotermitinae are good examples of subterranean nest builders, as they only dwell inside tunnels. [227], Termites can be major agricultural pests, particularly in East Africa and North Asia, where crop losses can be severe (3–100% in crop loss in Africa). [231], The development of autonomous robots capable of constructing intricate structures without human assistance has been inspired by the complex mounds that termites build. It is assumed that more than 90 percent of dry wood in the semiarid savannah ecosystems of Africa and Asia are reprocessed by these termites. [39] Of the 3,000 termite species currently classified, 1,000 are found in Africa, where mounds are extremely abundant in certain regions. The queen only lays 10–20 eggs in the very early stages of the colony, but lays as many as 1,000 a day when the colony is several years old. [220] These insects are particularly important in impoverished countries where malnutrition is common, as the protein from termites can help improve the human diet. The animate is all of the termites living inside the colony, and the inanimate part is the structure itself, which is constructed by the termites. Updates? Termites can also damage laminate flooring and even skirting boards. Subterranean termites prefer softwoods, but may invade most species of wood. Though harder to acquire, queens are regarded as a delicacy. [62] As a result, certain beetles and flies have evolved with their hosts. Coeditor of. [221], Alates are collected when the rainy season begins. the age of the carcass). Wear pattern analysis of bone tools used by the early hominin Paranthropus robustus suggests that they used these tools to dig into termite mounds. Termite antennae have a number of functions such as the sensing of touch, taste, odours (including pheromones), heat and vibration. Evolution, paleontology, and classification, https://www.britannica.com/animal/termite, termite - Children's Encyclopedia (Ages 8-11), termite - Student Encyclopedia (Ages 11 and up), Learn how termites use salivary secretions to cement debris to decaying wood nests in their rainforest habitat. The three basic segments of a termite antenna include a scape, a pedicel (typically shorter than the scape), and the flagellum (all segments beyond the scape and pedicel). Mastotermitidae Appearance. [217] The goal of termite control is to keep structures and susceptible ornamental plants free from termites. termite holes. When they do, they excavate a chamber big enough for both, close up the entrance and proceed to mate. When termites feed on the paper, they carry the remains to their colonies and thus continue feeding on it thus complete destruction. [196] A nest has many functions such as providing a protected living space and providing shelter against predators. Our editors will review what you’ve submitted and determine whether to revise the article. [15][16] Termites and Cryptocercus share similar morphological and social features: for example, most cockroaches do not exhibit social characteristics, but Cryptocercus takes care of its young and exhibits other social behaviour such as trophallaxis and allogrooming. [11] In 2008 DNA analysis from 16S rRNA sequences[12] supported the position of termites being nested within the evolutionary tree containing the order Blattodea, which included the cockroaches. [10] In the 1960s additional evidence supporting that hypothesis emerged when F. A. McKittrick noted similar morphological characteristics between some termites and Cryptocercus nymphs. [144] Foraging workers use semiochemicals to communicate with each other,[145] and workers who begin to forage outside of their nest release trail pheromones from their sternal glands. [50] There are ten tergites, of which nine are wide and one is elongated. [6] "Termite" derives from the Latin and Late Latin word termes ("woodworm, white ant"), altered by the influence of Latin terere ("to rub, wear, erode") from the earlier word tarmes. In the second phase, workers appear in large numbers at the site. All that damage because termites love wood and they’ll work their way up from your home’s foundation.This could lead to deadly structural damage. [92] Termites rely primarily upon symbiotic protozoa (metamonads) and other microbes such as flagellate protists in their guts to digest the cellulose for them, allowing them to absorb the end products for their own use. However, Mastotermitidae termites have multiflagellate sperm with limited motility. [25] The oldest termite nest discovered is believed to be from the Upper Cretaceous in West Texas, where the oldest known faecal pellets were also discovered. Some species, such as the West Indian drywood termite (Cryptotermes brevis), are regarded as invasive species. They are regarded as pleasant in taste, having a nut-like flavour after they are cooked. A damp and wet … Oil is not required as their bodies usually contain sufficient amounts of oil. Termiticide also works by spreading like a virus. [55] Studies show that in comparison to larger termites, smaller termites cannot fly long distances. When they find a food source, they communicate to other soldiers and a small force of workers starts to emerge. † Termopsidae[2] [141][142], Because the worker and soldier castes lack wings and thus never fly, and the reproductives use their wings for just a brief amount of time, termites predominantly rely upon their legs to move about. It is unknown whether the termite was female or male. [47] The mouth parts contain a maxillae, a labium, and a set of mandibles. They maintain a "garden" of specialised fungi of genus Termitomyces, which are nourished by the excrement of the insects. [59][100] Judging from closely related bacterial species, it is strongly presumed that the termites' and cockroach's gut microbiota derives from their dictyopteran ancestors. Termites are winged insects that feed on dead and decaying plant material. Not all nests are visible, as many nests in tropical forests are located underground. They have developed a gland that secrete a substance that attracts the workers by licking them. Termites are less likely to be attacked by parasites than bees, wasps and ants, as they are usually well protected in their mounds. [62] Additionally, an alarmed termite bumps into other termites which causes them to be alarmed and to leave pheromone trails to the disturbed area, which is also a way to recruit extra workers. Meanwhile, the higher termites consume a wide variety of materials, including faeces, humus, grass, leaves and roots. [241] Abandoned mounds are viewed as structures created by spirits, believing a local guardian dwells within the mound; this is known as Keramat and Datok Kong. [91] Termites are considered to be a major source (11%) of atmospheric methane, one of the prime greenhouse gases, produced from the breakdown of cellulose. [194] Nests can be broadly separated into three main categories: subterranean (completely below ground), epigeal (protruding above the soil surface), and arboreal (built above ground, but always connected to the ground via shelter tubes). [87] The form of parthenogenesis likely employed maintains heterozygosity in the passage of the genome from mother to daughter, thus avoiding inbreeding depression.

what is termites

Studies show that while termite queens mate with the king to produce colony workers, the queens reproduce their replacements (neotenic queens) parthenogenetically.[85][86]. [59] It frees the parents from feeding all but the first generation of offspring, allowing for the group to grow much larger and ensuring that the necessary gut symbionts are transferred from one generation to another. Previous estimates suggested the divergence took place during the Jurassic or Triassic. Worker termites are creamy colored, 3-4 mm long, and typically only seen when a mud foraging tube is broken, or infested wood is broken open. Termites are among the most successful groups of insects on Earth, colonising most landmasses except Antarctica. [216], 43 termite species are used as food by humans or are fed to livestock. In some species, eggs go through four moulting stages and nymphs go through three. [68], Termites are often compared with the social Hymenoptera (ants and various species of bees and wasps), but their differing evolutionary origins result in major differences in life cycle. More recently developed, less expensive alternatives include tracking the termites using egg white, cow milk, or soy milk proteins, which can be sprayed on termites in the field. [140] M. anisopliae is known to weaken the termite immune system. Rhinotermitidae [45] The alates (winged males and females) have eyes along with lateral ocelli. [95] Gut protozoa, such as Trichonympha, in turn, rely on symbiotic bacteria embedded on their surfaces to produce some of the necessary digestive enzymes. Stolotermitidae Most attacks occur at harvest time; crops and trees are attacked during the dry season. [57][58] Workers are tasked with the digestion of cellulose in food and are thus the most likely caste to be found in infested wood. Aluminiu… [123], Among all predators, ants are the greatest enemy to termites. [6] Most of the time, the alates are poor flyers; their technique is to launch themselves in the air and fly in a random direction. ", "Virus-like symptoms in a termite (Isoptera: Kalotermitidae) field colony", "Lévy flights and self-similar exploratory behaviour of termite workers: beyond model fitting", "A gene necessary for reproductive suppression in termites", "Predation and interference competition between ants (Hymenoptera: Formicidae) and arboreal termites (Isoptera: Termitidae)", "Intracolony chemical communication in social insects", "Soldier morphogenesis in a nasute termite: discovery of a disc-like structure forming a soldier nasus", "Structure and function of defensive glands in soldiers of, "Differential undertaking response of a lower termite to congeneric and conspecific corpses", "Do termites avoid carcasses? [179] The developed appendages on the physogastric abdomen of Austrospirachtha mimetes allows the beetle to mimic a termite worker. [198] Other building materials include partly digested plant material, used in carton nests (arboreal nests built from faecal elements and wood), and soil, used in subterranean nest and mound construction. [208] These passageways are made from soil and faeces and are normally brown in colour. [3], The primitive giant northern termite (Mastotermes darwiniensis) exhibits numerous cockroach-like characteristics that are not shared with other termites, such as laying its eggs in rafts and having anal lobes on the wings. You can also check if your floor feels more spongy and perhaps springs more than usual. Serritermitidae [199] Nests made out of carton are particularly weak, and so the inhabitants use counter-attack strategies against invading predators. [39], Due to their soft cuticles, termites do not inhabit cool or cold habitats. [215], The damage caused by termites costs the southwestern United States approximately $1.5 billion each year in wood structure damage, but the true cost of damage worldwide cannot be determined. Termites are important in two ways. [164] In cases where the intrusion is coming from a breach that is larger than the soldier's head, soldiers form a phalanx-like formation around the breach and bite at intruders. [162] Other methods of defence include intense jerking and secretion of fluids from the frontal gland and defecating faeces containing alarm pheromones. Phylogenetic studies have shown that the closest relative to the termite is the cockroach; for this reason termites are sometimes placed in the order Dictyoptera, which also contains the mantids. [46] When termites go out to look for food, they forage in columns along the ground through vegetation. [127] In rare cases, certain species of termites live inside active ant colonies. C. formosanus is unusual for the family in that it can survive without direct soil contact as long as a moisture source is present. Arboreal termites nests can account for as much as 2% of above ground carbon storage in Puerto Rican mangrove swamps. As the towers heat up, the solar chimney effect (stack effect) creates an updraft of air within the mound. [189] One flower in particular, Rhizanthella gardneri, is regularly pollinated by foraging workers, and it is perhaps the only Orchidaceae flower in the world to be pollinated by termites. [241], This article is about social The latter characteristically do not have Pseudergate nymphs (many "lower termite" worker nymphs have the capacity to develop into reproductive castes: see below). [79] The number of termites in a colony also varies, with the larger species typically having 100–1,000 individuals. [215] Termites may attack trees whose resistance to damage is low but generally ignore fast-growing plants. [62] Termites can also communicate through mechanical cues, vibrations, and physical contact. In Central America and the West Indies, there are 17 pest species. [29] The folded wings of the fossil wood roach Pycnoblattina, arranged in a convex pattern between segments 1a and 2a, resemble those seen in Mastotermes, the only living insect with the same pattern. [124][125] Paltothyreus tarsatus is another termite-raiding species, with each individual stacking as many termites as possible in its mandibles before returning home, all the while recruiting additional nestmates to the raiding site through chemical trails. [69] In some species, the abdomen of the queen swells up dramatically to increase fecundity, a characteristic known as physogastrism. [80] The two mature ovaries may have some 2,000 ovarioles each. [110] The Malaysian basicerotine ants Eurhopalothrix heliscata uses a different strategy of termite hunting by pressing themselves into tight spaces, as they hunt through rotting wood housing termite colonies. The north–south orientation causes the internal temperature of a mound to increase rapidly during the morning while avoiding overheating from the midday sun.

Although only about 10 percent of the 2,750 known termite species have been reported as pests, many of these cause severe and extremely costly damage. The process of worker termites feeding other nestmates is known as trophallaxis. [157][182] Despite this, some termites and ants can coexist peacefully. These long-lived queens have a significantly lower level of oxidative damage, including oxidative DNA damage, than workers, soldiers and nymphs. When the swarming termites leave the nest, the nymph termites seal the holes. Coptotermes formosanus, widely distributed in Japan, Taiwan, and South China, has been introduced into Sri Lanka (Ceylon), the Pacific islands, South Africa, East Africa, Hawaii, California, and the southern United States. [42], Termites are usually small, measuring between 4 to 15 millimetres (0.16 to 0.59 in) in length. [221][222] Termite mounds are the main sources of soil consumption (geophagy) in many countries including Kenya, Tanzania, Zambia, Zimbabwe and South Africa. [110] Tetramorium uelense is a specialised predator species that feeds on small termites. [145], Termites can distinguish nestmates and non-nestmates through chemical communication and gut symbionts: chemicals consisting of hydrocarbons released from the cuticle allow the recognition of alien termite species. [71], The life cycle of a termite begins with an egg, but is different from that of a bee or ant in that it goes through a developmental process called incomplete metamorphosis, with egg, nymph and adult stages. This material disrupts normal formation of the exoskeleton (cuticle) of molting workers (the only caste capable of molting), resulting in death of the workers and, eventually, the rest of the colony. [47] Each segment contains a pair of legs. Termites Often mistaken as white ants, termites do differ from ants in terms of how they act and what they look like. Since they feed on wood nonstop, a termite For example, though they might block each other's passages, colonies of Macrotermes bellicosus and Macrotermes subhyalinus are not always aggressive towards each other. [200] Mounds located in areas with torrential and continuous rainfall are at risk of mound erosion due to their clay-rich construction. Several hundred species are economically significant as pests that can cause serious damage to buildings, crops, or plantation forests. [62], Termites are known to carry pollen and regularly visit flowers,[188] so are regarded as potential pollinators for a number of flowering plants. Another method is to place insecticide into small holes drilled into galleries of infested wood. [41] There are three ecological groups of termites: dampwood, drywood and subterranean. Termites occur also in the Cape region of South Africa, Australia, Tasmania, and New Zealand. [234] These robots work independently and can move by themselves on a tracked grid, capable of climbing and lifting up bricks. Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are the sister group to wood eating cockroaches of the genus Cryptocercus. [207], Cathedral mounds in the Northern Territory, Australia, Mounds of "compass" or "magnetic" termites (Amitermes) oriented north–south, thereby avoiding mid-day heat, Termites in a mound, Analamazoatra Reserve, Madagascar, Termites construct shelter tubes, also known as earthen tubes or mud tubes, that start from the ground. [40] In Asia, there are 435 species of termites, which are mainly distributed in China. In many parts of Africa, the alates are an important factor in the diets of native populations. Termites are infected by viruses including Entomopoxvirinae and the Nuclear Polyhedrosis Virus. Within China, termite species are restricted to mild tropical and subtropical habitats south of the Yangtze River. What do Drywood Termites Look Like? [201], Some species build complex nests called polycalic nests; this habitat is called polycalism. Termite droppings or commonly known as frass is one of the common signs of termite infestation in your house. [146] In one species, Nasutitermes costalis, there are three phases in a foraging expedition: first, soldiers scout an area. Lateral ocelli, however, are not found in all termites, absent in the families Hodotermitidae, Termopsidae, and Archotermopsidae. [61][62] Fontanelles, simple holes in the forehead that exude defensive secretions, are a feature of the family Rhinotermitidae. [115][116][117] Other predators include aardvarks, aardwolves, anteaters, bats, bears, bilbies, many birds, echidnas, foxes, galagos, numbats, mice and pangolins. In the Far East Reticulitermes speratus ranges as far north as South Korea, Peking, and northern Japan. These supplementary reproductives only mature into primary reproductives upon the death of a king or queen, or when the primary reproductives are separated from the colony. If it was a female, the body length would be far greater than 25 millimetres when mature. Nests and mounds protect the termites' soft bodies against desiccation, light, pathogens and parasites, as well as providing a fortification against predators. [209] Shelter tubes also provide high humidity and darkness and allow workers to collect food sources that cannot be accessed in any other way. These fights can cause mortality on both sides and, in some cases, the gain or loss of territory. [104][105] Molecular evidence suggests that the family Macrotermitinae developed agriculture about 31 million years ago. For example, Megaponera is a strictly termite-eating (termitophagous) genus that perform raiding activities, some lasting several hours. Specific structures or other objects such as pellets of soil or pillars cause termites to start building. Dry-wood termites nest in the wood on which they feed and do not invade a structure from the soil. Termite monitors made of wood or cellulose adjacent to a structure may also provide indication of termite foraging activity where it will be in conflict with humans. Thermites have diverse compositions. Nuptial flight time varies in each species. Cryptotermes brevis, the most widely introduced invasive termite species in the world, has been introduced to all the islands in the West Indies and to Australia. Instead, like juveniles, they are fed by workers. Originally living in the rainforest, fungus farming allowed them to colonise the African savannah and other new environments, eventually expanding into Asia. [81] The abdomen increases the queen's body length to several times more than before mating and reduces her ability to move freely; attendant workers provide assistance. A termite nest can be considered as being composed of two parts, the inanimate and the animate. Termites are found on all continents except Antarctica. Termite workers, by comparison, are transparent, light or creamy white in color, and they avoid light. [65] A wide variety of monoterpene hydrocarbon solvents have been identified in the liquids that nasutes secrete. The diversity of termite species is low in North America and Europe (10 species known in Europe and 50 in North America), but is high in South America, where over 400 species are known. Winged, reproductive termites are frequently mistaken for flying ants, but are smaller than ants and have straight, rather than bent, antennae. Males (drones) are haploid and develop from unfertilised eggs, while females (both workers and the queen) are diploid and develop from fertilised eggs. Termites are consumed in many regions globally, but this practice has only become popular in developed nations in recent years. [54], Unlike in ants, the hind-wings and fore-wings are of equal length. Termites that cause damage to Australian homes are subterranean termites. [154] Suicide cramming is known in Coptotermes formosanus. [58][61] Among certain termites, soldiers may use their globular (phragmotic) heads to block their narrow tunnels. Termite Facts for Kids. These Nasutitermes nests are mainly composed of partially biodegraded wood material from the stems and branches of mangrove trees, namely, Rhizophora mangle (red mangrove), Avicennia germinans (black mangrove) and Laguncularia racemose (white mangrove). Long Island is the most populated island in any US state. Subterranean termites are small, soft bodied insects that build large nests in soil or trees and have underground tunnels that can reach up to 100 metres away from the nest. Mounds may also provide shelter and warmth to birds, lizards, snakes and scorpions. These swarms attract a wide variety of predators. About 3,106 species are currently described, with a few hundred more left to be described. [221], In addition to Africa, termites are consumed in local or tribal areas in Asia and North and South America. [210], Drywood termites thrive in warm climates, and human activities can enable them to invade homes since they can be transported through contaminated goods, containers and ships. [56], Worker termites undertake the most labour within the colony, being responsible for foraging, food storage, and brood and nest maintenance. [185][186] Iridomyrmex also inhabits termite mounds although no evidence for any kind of relationship (other than a predatory one) is known. Termite baits are poison-filled traps placed strategically around your home’s perimeter. [9], Termites were formerly placed in the order Isoptera. The termite adds these objects onto existing structures, and such behaviour encourages building behaviour in other workers. [72] Nymphs resemble small adults, and go through a series of moults as they grow. Termites and the ecosystem must go together, even if the latter has started to become mainly artificial. Preventive measures include the use of chemically treated wood in building construction and the use of paint or other durable finish to seal cracks in wood surfaces. The most common traditional control used around a structure is to flood a shallow trench with an insecticide and cover it with soil. [83], Termites going through incomplete metamorphosis on the path to becoming alates form a subcaste in certain species of termite, functioning as potential supplementary reproductives. [49] The number of tibial spurs on an individual's leg varies. A trail can be identified by the faecal deposits or runways that are covered by objects. † Archeorhinotermitidae [184], 54 species of ants are known to inhabit Nasutitermes mounds, both occupied and abandoned ones. [187] Some invertebrate organisms such as beetles, caterpillars, flies and millipedes are termitophiles and dwell inside termite colonies (they are unable to survive independently). These small brown balls, known as "termite balls", rarely kill the eggs, and in some cases the workers tend to them. [214] Some termites are considered invasive species. [197] Species in the subfamily Apicotermitinae are good examples of subterranean nest builders, as they only dwell inside tunnels. [227], Termites can be major agricultural pests, particularly in East Africa and North Asia, where crop losses can be severe (3–100% in crop loss in Africa). [231], The development of autonomous robots capable of constructing intricate structures without human assistance has been inspired by the complex mounds that termites build. It is assumed that more than 90 percent of dry wood in the semiarid savannah ecosystems of Africa and Asia are reprocessed by these termites. [39] Of the 3,000 termite species currently classified, 1,000 are found in Africa, where mounds are extremely abundant in certain regions. The queen only lays 10–20 eggs in the very early stages of the colony, but lays as many as 1,000 a day when the colony is several years old. [220] These insects are particularly important in impoverished countries where malnutrition is common, as the protein from termites can help improve the human diet. The animate is all of the termites living inside the colony, and the inanimate part is the structure itself, which is constructed by the termites. Updates? Termites can also damage laminate flooring and even skirting boards. Subterranean termites prefer softwoods, but may invade most species of wood. Though harder to acquire, queens are regarded as a delicacy. [62] As a result, certain beetles and flies have evolved with their hosts. Coeditor of. [221], Alates are collected when the rainy season begins. the age of the carcass). Wear pattern analysis of bone tools used by the early hominin Paranthropus robustus suggests that they used these tools to dig into termite mounds. Termite antennae have a number of functions such as the sensing of touch, taste, odours (including pheromones), heat and vibration. Evolution, paleontology, and classification, https://www.britannica.com/animal/termite, termite - Children's Encyclopedia (Ages 8-11), termite - Student Encyclopedia (Ages 11 and up), Learn how termites use salivary secretions to cement debris to decaying wood nests in their rainforest habitat. The three basic segments of a termite antenna include a scape, a pedicel (typically shorter than the scape), and the flagellum (all segments beyond the scape and pedicel). Mastotermitidae Appearance. [217] The goal of termite control is to keep structures and susceptible ornamental plants free from termites. termite holes. When they do, they excavate a chamber big enough for both, close up the entrance and proceed to mate. When termites feed on the paper, they carry the remains to their colonies and thus continue feeding on it thus complete destruction. [196] A nest has many functions such as providing a protected living space and providing shelter against predators. Our editors will review what you’ve submitted and determine whether to revise the article. [15][16] Termites and Cryptocercus share similar morphological and social features: for example, most cockroaches do not exhibit social characteristics, but Cryptocercus takes care of its young and exhibits other social behaviour such as trophallaxis and allogrooming. [11] In 2008 DNA analysis from 16S rRNA sequences[12] supported the position of termites being nested within the evolutionary tree containing the order Blattodea, which included the cockroaches. [10] In the 1960s additional evidence supporting that hypothesis emerged when F. A. McKittrick noted similar morphological characteristics between some termites and Cryptocercus nymphs. [144] Foraging workers use semiochemicals to communicate with each other,[145] and workers who begin to forage outside of their nest release trail pheromones from their sternal glands. [50] There are ten tergites, of which nine are wide and one is elongated. [6] "Termite" derives from the Latin and Late Latin word termes ("woodworm, white ant"), altered by the influence of Latin terere ("to rub, wear, erode") from the earlier word tarmes. In the second phase, workers appear in large numbers at the site. All that damage because termites love wood and they’ll work their way up from your home’s foundation.This could lead to deadly structural damage. [92] Termites rely primarily upon symbiotic protozoa (metamonads) and other microbes such as flagellate protists in their guts to digest the cellulose for them, allowing them to absorb the end products for their own use. However, Mastotermitidae termites have multiflagellate sperm with limited motility. [25] The oldest termite nest discovered is believed to be from the Upper Cretaceous in West Texas, where the oldest known faecal pellets were also discovered. Some species, such as the West Indian drywood termite (Cryptotermes brevis), are regarded as invasive species. They are regarded as pleasant in taste, having a nut-like flavour after they are cooked. A damp and wet … Oil is not required as their bodies usually contain sufficient amounts of oil. Termiticide also works by spreading like a virus. [55] Studies show that in comparison to larger termites, smaller termites cannot fly long distances. When they find a food source, they communicate to other soldiers and a small force of workers starts to emerge. † Termopsidae[2] [141][142], Because the worker and soldier castes lack wings and thus never fly, and the reproductives use their wings for just a brief amount of time, termites predominantly rely upon their legs to move about. It is unknown whether the termite was female or male. [47] The mouth parts contain a maxillae, a labium, and a set of mandibles. They maintain a "garden" of specialised fungi of genus Termitomyces, which are nourished by the excrement of the insects. [59][100] Judging from closely related bacterial species, it is strongly presumed that the termites' and cockroach's gut microbiota derives from their dictyopteran ancestors. Termites are winged insects that feed on dead and decaying plant material. Not all nests are visible, as many nests in tropical forests are located underground. They have developed a gland that secrete a substance that attracts the workers by licking them. Termites are less likely to be attacked by parasites than bees, wasps and ants, as they are usually well protected in their mounds. [62] Additionally, an alarmed termite bumps into other termites which causes them to be alarmed and to leave pheromone trails to the disturbed area, which is also a way to recruit extra workers. Meanwhile, the higher termites consume a wide variety of materials, including faeces, humus, grass, leaves and roots. [241] Abandoned mounds are viewed as structures created by spirits, believing a local guardian dwells within the mound; this is known as Keramat and Datok Kong. [91] Termites are considered to be a major source (11%) of atmospheric methane, one of the prime greenhouse gases, produced from the breakdown of cellulose. [194] Nests can be broadly separated into three main categories: subterranean (completely below ground), epigeal (protruding above the soil surface), and arboreal (built above ground, but always connected to the ground via shelter tubes). [87] The form of parthenogenesis likely employed maintains heterozygosity in the passage of the genome from mother to daughter, thus avoiding inbreeding depression.
