[221], Alates are collected when the rainy season begins. termite holes. [157][182] Despite this, some termites and ants can coexist peacefully. [77] The lower levels of damage appear to be due to increased catalase, an enzyme that protects against oxidative stress. [145][158], When termites construct their nests, they use predominantly indirect communication. Termites are among the most successful groups of insects on Earth, colonising most landmasses except Antarctica. In Europe the northern limit of natural distribution is reached by Reticulitermes lucifugus on the Atlantic coast of France, although an introduced species, Reticulitermes flavipes, occurs as far north as Hamburg, Germany. [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. [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. [137] Fungal pathogens such as Aspergillus nomius and Metarhizium anisopliae are, however, major threats to a termite colony as they are not host-specific and may infect large portions of the colony;[138][139] transmission usually occurs via direct physical contact. [9], Termites were formerly placed in the order Isoptera. Regular and thorough inspections by a trained professional may be necessary to detect termite activity in the absence of more obvious signs like termite swarmers or alates inside or adjacent to a structure. [176], A species of fungus is known to mimic termite eggs, successfully avoiding its natural predators. A commercial product, "Blockaid", has been developed in Australia that uses a range of plant extracts to create a paint-on nontoxic termite barrier for buildings. [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. Colonies are described as superorganisms because the termites form part of a self-regulating entity: the colony itself.[5]. [197] Primitive termites of today nest in wooden structures such as logs, stumps and the dead parts of trees, as did termites millions of years ago. [212] Of the 3,106 species known, only 183 species cause damage; 83 species cause significant damage to wooden structures. Termite workers, by comparison, are transparent, light or creamy white in color, and they avoid light. This odour is a result of genetic and environmental factors such as the termites' diet and the composition of the bacteria within the termites' intestines. [123], Among all predators, ants are the greatest enemy to termites. For example, Cubitermes colonies build narrow tunnels used as strong points, as the diameter of the tunnels is small enough for soldiers to block. [130], Ants are not the only invertebrates that perform raids. [61] Many soldiers have large heads with highly modified powerful jaws so enlarged they cannot feed themselves. [216], 43 termite species are used as food by humans or are fed to livestock. Termite swarmers have four wings that are all the same size. In contrast, worker termites, which constitute the majority in a colony, are diploid individuals of both sexes and develop from fertilised eggs. There are three distinct groups into which termites are divided: subterranean, drywood, and dampwood. The infraorder Isoptera is divided into the following clade and family groups, showing the subfamilies in their respective classification:[30]. The other termite stages cannot survive long outside the protective humid atmosphere of their … [183] The earliest known association between Azteca ants and Nasutitermes termites date back to the Oligocene to Miocene period. Meanwhile, the higher termites consume a wide variety of materials, including faeces, humus, grass, leaves and roots. These long-lived queens have a significantly lower level of oxidative damage, including oxidative DNA damage, than workers, soldiers and nymphs. [202], Nests are considered mounds if they protrude from the earth's surface. They are destructive when they feed upon, and often destroy, wooden structures or vegetable matter valuable to humans. Most varieties are not explosive, but can create brief bursts of heat and high temperature in a small area. [198] Certain areas in mounds are used as strong points in case of a breach. Dampwood termites are found only in coniferous forests, and drywood termites are found in hardwood forests; subterranean termites live in widely diverse areas. [231], The development of autonomous robots capable of constructing intricate structures without human assistance has been inspired by the complex mounds that termites build. Omissions? Termites are one of the most destructive wood destroying insects that homeowners commonly have to deal with. Nuptial flight time varies in each species. [118] The termite genera Apicotermes and Trinervitermes are known to have polycalic species. [201], Some species build complex nests called polycalic nests; this habitat is called polycalism. [195] Epigeal nests (mounds) protrude from the earth with ground contact and are made out of earth and mud. [21] Termites can be beneficial to agriculture, such as by boosting crop yields and enriching the soil. [235], Termites use sophisticated means to control the temperatures of their mounds. [19] Termites have long been accepted to be closely related to cockroaches and mantids, and they are classified in the same superorder (Dictyoptera). Termite shields (also called ant caps) don't prevent termite activity but bring it into the open, as it's easier to detect their mud shelter tubes on the metal caps. [200], Species in the genus Macrotermes arguably build the most complex structures in the insect world, constructing enormous mounds. [20][21], The oldest unambiguous termite fossils date to the early Cretaceous, but given the diversity of Cretaceous termites and early fossil records showing mutualism between microorganisms and these insects, they possibly originated earlier in the Jurassic or Triassic. [177] This fungus mimics these eggs by producing a cellulose-digesting enzyme known as glucosidases. Termites and the ecosystem must go together, even if the latter has started to become mainly artificial. Rhinotermitidae [145][163], In some species, some soldiers block tunnels to prevent their enemies from entering the nest, and they may deliberately rupture themselves as an act of defence. [155], Among the reproductive caste, neotenic queens may compete with each other to become the dominant queen when there are no primary reproductives. [118][110][129] In contrast to all these ant species, and despite their enormous diversity of prey, Dorylus ants rarely consume termites. Dampwood termites generally stay close to the ground, but will choose moist, decaying wood anywhere it is found. A social insect, the termite is closely related to both the mantis and the cockroach , and will follow the rest of its colony, which can number in the millions, to a location that has an abundance of food. When they find a food source, they communicate to other soldiers and a small force of workers starts to emerge. [64] Different sorts of soldiers include minor and major soldiers, and nasutes, which have a horn-like nozzle frontal projection (a nasus).

Cellulose digestion in "higher termites" has co-evolved with eukaryotic gut microbiota[38] and many genera have symbiotic relationships with fungi such as Termitomyces; in contrast, "lower termites" typically have flagellates and prokaryotes in their hindguts. The mesothorax and metathorax have well-developed exoskeletal plates; the prothorax has smaller plates. [56], Worker termites undertake the most labour within the colony, being responsible for foraging, food storage, and brood and nest maintenance. This is a darling to the termites. Not all nests are visible, as many nests in tropical forests are located underground. In particular, ants that prey on termites usually have a negative impact on arboreal nesting species. [179] The developed appendages on the physogastric abdomen of Austrospirachtha mimetes allows the beetle to mimic a termite worker. [87] The form of parthenogenesis likely employed maintains heterozygosity in the passage of the genome from mother to daughter, thus avoiding inbreeding depression. Termites are infected by viruses including Entomopoxvirinae and the Nuclear Polyhedrosis Virus. [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. Ants: ants are scavengers, with different species foraging for different foods. [173][174][175] To avoid pathogens, termites occasionally engage in necrophoresis, in which a nestmate carries away a corpse from the colony to dispose of it elsewhere. [156], Ants and termites may compete with each other for nesting space. [17] Termites are thought to be the descendants of the genus Cryptocercus. C. formosanus is unusual for the family in that it can survive without direct soil contact as long as a moisture source is present. [197] Species in the subfamily Apicotermitinae are good examples of subterranean nest builders, as they only dwell inside tunnels. In addition to naturally occurring termites, many species have been inadvertently transported by humans from their native habitats to new parts of the world. Termites Often mistaken as white ants, termites do differ from ants in terms of how they act and what they look like. [176] Which strategy is used depends on the nature of the corpse a worker is dealing with (i.e. [58][61] Among certain termites, soldiers may use their globular (phragmotic) heads to block their narrow tunnels. Its form of action is similar to that of other fuel-oxidizer mixtures, such as black powder. [136] Under imminent threat of an attack by parasites, a colony may migrate to a new location. 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). These fights can cause mortality on both sides and, in some cases, the gain or loss of territory. 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. The third phase is marked by a decrease in the number of soldiers present and an increase in the number of workers. The most common traditional control used around a structure is to flood a shallow trench with an insecticide and cover it with soil. [231] Genetic engineering may enable hydrogen to be generated in bioreactors from woody biomass. [93][94]The microbial ecosystem present in the termite gut contains many species found nowhere else on Earth. Some termite species may rely on nymphs to perform work without differentiating as a separate caste. [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. [62] Another termite species, Amitermes meridionalis, can build nests 3 to 4 metres (9 to 13 feet) high and 2.5 metres (8 feet) wide. [236], Few zoos hold termites, due to the difficulty in keeping them captive and to the reluctance of authorities to permit potential pests. [62] As a result, certain beetles and flies have evolved with their hosts. What do Drywood Termites Look Like? Termites are less likely to be attacked by parasites than bees, wasps and ants, as they are usually well protected in their mounds. When kept close to the extract, they become disoriented and eventually die.[192]. The presence of nests in fields enables larger amounts of rainwater to soak into the ground and increases the amount of nitrogen in the soil, both essential for the growth of crops. Termites occur also in the Cape region of South Africa, Australia, Tasmania, and New Zealand. Some species of termite, including Nasutitermes corniger, form associations with certain ant species to keep away predatory ant species. Cryptotermes spp. Termites can be controlled by application of Bordeaux mixture or other substances that contain copper such as chromated copper arsenate. [221][222] Termite mounds are the main sources of soil consumption (geophagy) in many countries including Kenya, Tanzania, Zambia, Zimbabwe and South Africa. [178] A unique mimicking behaviour exists between various species of Trichopsenius beetles and certain termite species within Reticulitermes. Infection with A. nomius only occurs when a colony is under great stress. For other uses, see. [159][160] Each colony has its own distinct odour. 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. [40] In Asia, there are 435 species of termites, which are mainly distributed in China. Drywood Termites Facts, Identification & Control Latin Name. [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. [221] Groups have different ways of collecting or cultivating insects; sometimes collecting soldiers from several species. The solar chimney effect has been in use for centuries in the Middle East and Near East for passive cooling, as well as in Europe by the Romans. For example, Formica nigra captures termites, and those who try to escape are immediately seized and driven underground. [153] Conflict between two competitors does not always occur. The termites digest the cellulose in the board for food. [145] Alarm pheromones can be released when the nest has been breached or is being attacked by enemies or potential pathogens. [88][89][90] Many species eat cellulose, having a specialised midgut that breaks down the fibre. Several hundred species are economically significant as pests that can cause serious damage to buildings, crops, or plantation forests. [121][122] Sloth bears break open mounds to consume the nestmates, while chimpanzees have developed tools to "fish" termites from their nest. [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. Termites are found on all continents except Antarctica. [202] Polycalic nests appear to be less frequent in mound-building species although polycalic arboreal nests have been observed in a few species of Nasutitermes. A termite nest can be considered as being composed of two parts, the inanimate and the animate. [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). [28] Krishna et al., though, consider that all of the Paleozoic and Triassic insects tentatively classified as termites are in fact unrelated to termites and should be excluded from the Isoptera. 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. [181] Certain species of ants in the subfamily Ponerinae conduct these raids although other ant species go in alone to steal the eggs or nymphs. [104][105] Molecular evidence suggests that the family Macrotermitinae developed agriculture about 31 million years ago. [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. Which of these insects includes a “slave-maker” that bites the head off the resident queen? When a termite is in flight, its wings remain at a right angle, and when the termite is at rest, its wings remain parallel to the body. Because dry-wood termites (e.g., Cryptotermes species) live in small colonies in wood and tolerate long periods of dryness, they can survive in seasoned wood and furniture and can easily be transported over long distances. [61][62] Fontanelles, simple holes in the forehead that exude defensive secretions, are a feature of the family Rhinotermitidae. [234] These robots work independently and can move by themselves on a tracked grid, capable of climbing and lifting up bricks. Some termites feed on living plant materials and can become serious crop pests. [49] The tenth abdominal segment has a pair of short cerci. Most termites construct underground colonies rather than multifunctional nests and mounds. [58][75] Pheromones regulate the caste system in termite colonies, preventing all but a very few of the termites from becoming fertile queens. [30] Other studies suggest that the origin of termites is more recent, having diverged from Cryptocercus sometime during the Early Cretaceous. Professor of Biology, City College and the Graduate School, City University of New York. 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. Termites are rich in vitamin A, vitamin C, fat while anti-nutrient components were low. Fipronil. Termites are eusocial insects that are classified at the taxonomic rank of infraorder Isoptera, or as epifamily Termitoidae within the order Blattodea (along with cockroaches). [195], To build their nests, termites primarily use faeces, which have many desirable properties as a construction material. The Neoisoptera, literally meaning "newer termites" (in an evolutionary sense), are a recently coined nanorder that include families commonly referred-to as "higher termites", although some authorities only apply this term to the largest family Termitidae. [199] Nests made out of carton are particularly weak, and so the inhabitants use counter-attack strategies against invading predators. Termites typically swarm early in spring on a warm, sunny day. Termites … [49] The appearance of the legs is similar in each caste, but the soldiers have larger and heavier legs. [69][75] If a queen is absent, a termite king produces pheromones which encourage the development of replacement termite queens. A scout recruits 10–30 workers to an area where termites are present, killing them by immobilising them with their stinger. [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. Please refer to the appropriate style manual or other sources if you have any questions. [53], The non-reproductive castes of termites are wingless and rely exclusively on their six legs for locomotion. [39] In Australia, all ecological groups of termites (dampwood, drywood, subterranean) are endemic to the country, with over 360 classified species. [96][97][98] Researches have found species of spirochetes living in termite guts capable of fixing atmospheric nitrogen to a form usable by the insect. Termites can be found in every state except for Alaska. Termite Characteristics. [161], Termites rely on alarm communication to defend a colony. The structure of the legs is consistent with other insects: the parts of a leg include a coxa, trochanter, femur, tibia and the tarsus. [39] Of the 3,000 termite species currently classified, 1,000 are found in Africa, where mounds are extremely abundant in certain regions. [50] There are ten tergites, of which nine are wide and one is elongated. Unlike in other termites, Mastotermitidae females have an ovipositor, a feature strikingly similar to that in female cockroaches. One termite species alone, Hodotermes mossambicus, was found in the stomach contents of 65 birds and 19 mammals. [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. Termite infestation is the infiltration of a termite colony which typically results in damage to the infested structure, whether it be a building, garden, or crop. They range from less than 1 cm to several cm in width, but may be dozens of metres in length. Termites will chew through lead, asphalt, plaster or mortar to find wood. [162] Other methods of defence include intense jerking and secretion of fluids from the frontal gland and defecating faeces containing alarm pheromones. Unlike ants, termites live off a strict diet of cellulose. [210] Less than 10% of drywood termites are pests, but they infect wooden structures and furniture in tropical, subtropical and other regions. Males (drones) are haploid and develop from unfertilised eggs, while females (both workers and the queen) are diploid and develop from fertilised eggs. Because their colonies are within the structure, they are difficult to control. Termite, (order Isoptera), any of a group of cellulose-eating insects, the social system of which shows remarkable parallels with those of ants and bees, although it has evolved independently.Even though termites are not closely related to ants, they are sometimes referred to as white ants. [63] Many species are readily identified using the characteristics of the soldiers' larger and darker head and large mandibles. [62], The pantropical subfamily Nasutitermitinae has a specialised caste of soldiers, known as nasutes, that have the ability to exude noxious liquids through a horn-like frontal projection that they use for defence. Termites can also attack other plants, including cassava, coffee, cotton, fruit trees, maize, peanuts, soybeans and vegetables. Originally living in the rainforest, fungus farming allowed them to colonise the African savannah and other new environments, eventually expanding into Asia. [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. Those made from carton can provide protection from the rain, and in fact can withstand high precipitation. Termite Inspection What Does Termite Inspection Entail A termite inspection is a visual inspection of the readily accessible areas of a home for evidence of wood-destroying insects. Termites are detritivores, consuming dead plants at any level of decomposition. Termites and ants can re-colonise untilled land that contains crop stubble, which colonies use for nourishment when they establish their nests. The alates fly only for a brief amount of time, so they also rely on their legs. Polycalic species of termites form multiple nests, or calies, connected by subterranean chambers. They also play a vital role in the ecosystem by recycling waste material such as dead wood, faeces and plants. Drywood termites are often found in attics and require little moisture in the wood they eat. Appearance. Such robots may be useful for future projects on Mars, or for building levees to prevent flooding. [210] Termites play an important role as decomposers of wood and vegetative material, and the conflict with humans occurs where structures and landscapes containing structural wood components, cellulose derived structural materials and ornamental vegetation provide termites with a reliable source of food and moisture. The process of worker termites feeding other nestmates is known as trophallaxis. [10] In the 1960s additional evidence supporting that hypothesis emerged when F. A. McKittrick noted similar morphological characteristics between some termites and Cryptocercus nymphs. When the swarming termites leave the nest, the nymph termites seal the holes. In Central America and the West Indies, there are 17 pest species. The size of these shelter tubes depends on the number of food sources that are available. The protein content of termites is higher than in beef. [200], Arboreal carton nests of mangrove swamp-dwelling Nasutitermes are enriched in lignin and depleted in cellulose and xylans. [13][14] The cockroach genus Cryptocercus shares the strongest phylogenetical similarity with termites and is considered to be a sister-group to termites. Which beetle is also known as the tumblebug and can eat its weight in 24 hours? Their colonies range in size from a few hundred individuals to enormous societies with several million individuals.
