[43] Another giant termite, the extinct Gyatermes styriensis, flourished in Austria during the Miocene and had a wingspan of 76 millimetres (3.0 in) and a body length of 25 millimetres (0.98 in). [69][75] If a queen is absent, a termite king produces pheromones which encourage the development of replacement termite queens. Does it refer to the average life-span of an insect or the amount of time a particular species of insect has existed? [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. They is no way to know for sure how long it takes for wood destroying insects to damage a home. [197] Species in the subfamily Apicotermitinae are good examples of subterranean nest builders, as they only dwell inside tunnels. They're Enemy Number One for woodworkers. Termites are less likely to be attacked by parasites than bees, wasps and ants, as they are usually well protected in their mounds. Once they have established themselves they can do considerable damage in a short period of time. This insect turns wood into fine flour like powder as it meanders through the timber in your home. [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. Some of these include dipteran flies,[134] Pyemotes mites, and a large number of nematode parasites. [74][84] Supplementaries have the ability to replace a dead primary reproductive, and there may also be more than a single supplementary within a colony. In some species, eggs go through four moulting stages and nymphs go through three. Most attacks occur at harvest time; crops and trees are attacked during the dry season. [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. [48], Termites have a ten-segmented abdomen with two plates, the tergites and the sternites. For example, though they might block each other's passages, colonies of Macrotermes bellicosus and Macrotermes subhyalinus are not always aggressive towards each other. [155], Among the reproductive caste, neotenic queens may compete with each other to become the dominant queen when there are no primary reproductives. The north–south orientation causes the internal temperature of a mound to increase rapidly during the morning while avoiding overheating from the midday sun. There's at least one species of long-horned beetle that beats out the cicada with its ability to survive in its larval form in dead wood for thirty-five to fifty years. [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. Termites hatch without these symbionts present in their guts, and develop them after fed a culture from other termites. [153] Conflict between two competitors does not always occur. The potential for damage from any of Email; The longest living insect in the world is Phobaeticus Chani, also known as Chan’s megastick.We showed you some giant insects in here before and knew that the record was hold by Borneo native Phobaeticus kirbyi, at more than 14 inches (35.6 cm), but not anymore. [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. [196] A nest has many functions such as providing a protected living space and providing shelter against predators. [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. [61][62] Fontanelles, simple holes in the forehead that exude defensive secretions, are a feature of the family Rhinotermitidae. [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. [231], The development of autonomous robots capable of constructing intricate structures without human assistance has been inspired by the complex mounds that termites build. Insects have been here on Earth long before humans, and they are here to stay. When kept close to the extract, they become disoriented and eventually die.[192]. [191] This reduces the ability of termites to efficiently digest the cellulose. [157], Most termites are blind, so communication primarily occurs through chemical, mechanical and pheromonal cues. Although these insects are often called "white ants",[4] they are not ants, and are not closely related to ants. Queen termites (Isoptera), previously thought to live 10 years or more, are now known to … [204], The sculptured mounds sometimes have elaborate and distinctive forms, such as those of the compass termite (Amitermes meridionalis and A. laurensis), which builds tall, wedge-shaped mounds with the long axis oriented approximately north–south, which gives them their common name. [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. [231][233] Through the action of unidentified enzymes in the termite gut, lignocellulose polymers are broken down into sugars and are transformed into hydrogen. [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. These include roundheaded wood borers, flatheaded wood borers, and shothole borers, also called powderpost beetles. [145] Alarm pheromones can be released when the nest has been breached or is being attacked by enemies or potential pathogens. The longest living insects are the Splendour beetles (Buprestidae), some of which remain in the larva stage for more than 30 years. [46] When termites go out to look for food, they forage in columns along the ground through vegetation. [102], Various woods differ in their susceptibility to termite attack; the differences are attributed to such factors as moisture content, hardness, and resin and lignin content. Some species of termite have an arolium, located between the claws, which is present in species that climb on smooth surfaces but is absent in most termites. Yet, some insects live comparatively really long lives. 3. Longhorned Beetles. A termite nest is also known as a termitary or termitarium (plural termitaria or termitariums). [87] The form of parthenogenesis likely employed maintains heterozygosity in the passage of the genome from mother to daughter, thus avoiding inbreeding depression. Also known as Buprestidae and part of the jewel beetle family, this beetle has quite the lifespan, though not all of it is productive. [62][145] These signals are frequently used for alarm communication or for evaluating a food source. [99] Scientists' understanding of the relationship between the termite digestive tract and the microbial endosymbionts is still rudimentary; what is true in all termite species, however, is that the workers feed the other members of the colony with substances derived from the digestion of plant material, either from the mouth or anus. This chemical mimicry allows the beetles to integrate themselves within the termite colonies. [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. [191] An extract of a species of Australian figwort, Eremophila, has been shown to repel termites;[192] tests have shown that termites are strongly repelled by the toxic material to the extent that they will starve rather than consume the food. [31] It has been proposed that the Isoptera and Cryptocercidae be grouped in the clade "Xylophagodea". The size of these shelter tubes depends on the number of food sources that are available. We will look at both here, but first is a list of the former. Wood wasps also leave holes in Sheetrock. [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. [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. [154] Suicide cramming is known in Coptotermes formosanus. Termites mostly feed on dead plant material and cellulose, generally in the form of wood, leaf litter, soil, or animal dung. Dampwood termites are found only in coniferous forests, and drywood termites are found in hardwood forests; subterranean termites live in widely diverse areas. These termites are known in part for the large mounds they build. [176], A species of fungus is known to mimic termite eggs, successfully avoiding its natural predators. [229] In South America, cultivated plants such as eucalyptus, upland rice and sugarcane can be severely damaged by termite infestations, with attacks on leaves, roots and woody tissue. They are reddish-brown to black in color and can grow up to 3/4” long and can be a … In Central America and the West Indies, there are 17 pest species. When they find a food source, they communicate to other soldiers and a small force of workers starts to emerge. [198] These mounds are among the largest in the world, reaching a height of 8 to 9 metres (26 to 29 feet), and consist of chimneys, pinnacles and ridges. Some do live much longer, though, and my guess is that the periodic cicada holds the record. For other uses, see. When they finally do rise from under the ground, their adult lives are over before they've hardly begun. ;[218] Structures may be homes or business, or elements such as wooden fence posts and telephone poles. [145][158], When termites construct their nests, they use predominantly indirect communication. [230], The termite gut has inspired various research efforts aimed at replacing fossil fuels with cleaner, renewable energy sources. [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. For example, alates in certain species emerge during the day in summer while others emerge during the winter. [10] In the 1960s additional evidence supporting that hypothesis emerged when F. A. McKittrick noted similar morphological characteristics between some termites and Cryptocercus nymphs. During that time of the year where ants start flying around, ants are mating. They vary from 0.25 to 3 inches in length. [198] Certain areas in mounds are used as strong points in case of a breach. [205][206] This orientation has been experimentally shown to assist thermoregulation. 5.The longest living insect that eats up all the wood. A scout recruits 10–30 workers to an area where termites are present, killing them by immobilising them with their stinger. The neotropical termite Embiratermes neotenicus and several other related species produce colonies that contain a primary king accompanied by a primary queen or by up to 200 neotenic queens that had originated through thelytokous parthenogenesis of a founding primary queen. [66] Soldiers are usually sterile but some species of Archotermopsidae are known to have neotenic forms with soldier-like heads while also having sexual organs. [140] M. anisopliae is known to weaken the termite immune system. Chameleon . Termite queens have the longest known lifespan of any insect, with some queens reportedly living up to 30 to 50 years. The larvae then bore large galleries deep into the wood. Termites are major detritivores, particularly in the subtropical and tropical regions, and their recycling of wood and plant matter is of considerable ecological importance. [171] The soldiers of the neotropical termite family Serritermitidae have a defence strategy which involves front gland autothysis, with the body rupturing between the head and abdomen. Beetles are the most common group found developing in firewood. Stolotermitidae Deathwatch beetles. [235], Termites use sophisticated means to control the temperatures of their mounds. termites, both subterranean termitesand drywood termites, carpenter antsand certain powderpost beetlesare the primary insects that can destroy wood. † Termopsidae[2] [149][150] "Cemetery pits" may be present, where the bodies of dead termites are buried. [220], Termites are consumed by people in many different cultures around the world. These long-lived queens have a significantly lower level of oxidative damage, including oxidative DNA damage, than workers, soldiers and nymphs. [237] It is only relatively recently, however, that climate responsive construction techniques have become incorporated into modern architecture. [168], Soldiers of the species Globitermes sulphureus commit suicide by autothysis – rupturing a large gland just beneath the surface of their cuticles. However, some termite colonies, including those with many individuals, can number in the millions.[44]. [104][105] Molecular evidence suggests that the family Macrotermitinae developed agriculture about 31 million years ago. [123], Among all predators, ants are the greatest enemy to termites. One termite species alone, Hodotermes mossambicus, was found in the stomach contents of 65 birds and 19 mammals. Sterile workers are sometimes termed as true workers while those that are fertile, as in the wood-nesting Archotermopsidae, are termed as false workers. [63] Many species are readily identified using the characteristics of the soldiers' larger and darker head and large mandibles. [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. They have developed a gland that secrete a substance that attracts the workers by licking them. The third phase is marked by a decrease in the number of soldiers present and an increase in the number of workers. [202], Nests are considered mounds if they protrude from the earth's surface. The termite adds these objects onto existing structures, and such behaviour encourages building behaviour in other workers. 2. Kalotermitidae Check out this list of some of the weirdest (and coolest) ones we could find. When soldiers guarding nest entrances are attacked by intruders, they engage in autothysis, creating a block that denies entry to any attacker. [88][89][90] Many species eat cellulose, having a specialised midgut that breaks down the fibre. When the fungi are eaten, their spores pass undamaged through the intestines of the termites to complete the cycle by germinating in the fresh faecal pellets. They maintain a "garden" of specialised fungi of genus Termitomyces, which are nourished by the excrement of the insects. A Brazilian study investigated the termite assemblages of three sites of Caatinga under different levels of anthropogenic disturbance in the semi-arid region of northeastern Brazil were sampled using 65 x 2 m transects. [62] As a result, certain beetles and flies have evolved with their hosts. [28] It is even possible that the first termites emerged during the Carboniferous. The mesothorax and metathorax have well-developed exoskeletal plates; the prothorax has smaller plates. No evidence for any kind of relationship (other than a predatory one) is known. Studies show that while termite queens mate with the king to produce colony workers, the queens reproduce their replacements (neotenic queens) parthenogenetically.[85][86]. [217] The goal of termite control is to keep structures and susceptible ornamental plants free from termites. The maxillae and labium have palps that help termites sense food and handling. The thick, yellow fluid in the gland becomes very sticky on contact with the air, entangling ants or other insects that are trying to invade the nest. Specific structures or other objects such as pellets of soil or pillars cause termites to start building. [145] A number of pheromones are known, including contact pheromones (which are transmitted when workers are engaged in trophallaxis or grooming) and alarm, trail and sex pheromones. Some termite queens live longer than sixty years. Many bats, and almost all in the United States, thrive on an insect diet. [62], Termites are known to carry pollen and regularly visit flowers,[188] so are regarded as potential pollinators for a number of flowering plants. Termites always avoid nestmates infected with Metarhizium anisopliae spores, through vibrational signals released by infected nestmates. [210] Colonies of termites have been seen thriving in warm buildings located in cold regions. [95] Gut protozoa, such as Trichonympha, in turn, rely on symbiotic bacteria embedded on their surfaces to produce some of the necessary digestive enzymes. [64] Different sorts of soldiers include minor and major soldiers, and nasutes, which have a horn-like nozzle frontal projection (a nasus). Hope it helps :) lisha48 lisha48 (1) Kiwi bird (2) peacock (3) chameleons (4) polar bear (5) termite queen (or) Queens of termite. These beetles grow to 1/2 to 1 inch long and only attack softwoods, primarily pine. [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). [209], Owing to their wood-eating habits, many termite species can do significant damage to unprotected buildings and other wooden structures. Hodotermitidae These preferences may in part have represented conditioned or learned behaviour. Since C. formosanus colonies may get into physical conflict, some termites squeeze tightly into foraging tunnels and die, successfully blocking the tunnel and ending all agonistic activities. 1. Identification. [58][61] Among certain termites, soldiers may use their globular (phragmotic) heads to block their narrow tunnels. [210] In North America, 18 subterranean species are pests;[213] in Australia, 16 species have an economic impact; in the Indian subcontinent 26 species are considered pests, and in tropical Africa, 24. [58] Some queens have the ability to switch from sexual reproduction to asexual reproduction. Individual termites react rather than think, but at a group level, they exhibit a sort of collective cognition. Termites are consumed in many regions globally, but this practice has only become popular in developed nations in recent years. Infection with A. nomius only occurs when a colony is under great stress. Termites and ants can re-colonise untilled land that contains crop stubble, which colonies use for nourishment when they establish their nests. A black flying insect that burrows into wood is the carpenter bee. 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). [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. Colonies are described as superorganisms because the termites form part of a self-regulating entity: the colony itself.[5]. Dampwood termites only attack lumber material exposed to rainfall or soil. [79] The number of termites in a colony also varies, with the larger species typically having 100–1,000 individuals. Some scientists think they may live even longer than that. Termites are usually the most well-known when it comes to wood-eating insects because of the havoc they can wreak on a home. Polycalic species of termites form multiple nests, or calies, connected by subterranean chambers. 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. They can live for a whopping seventeen years. They also play a vital role in the ecosystem by recycling waste material such as dead wood, faeces and plants. They look something like haystacks, but more solid, like stone. [39] In Australia, all ecological groups of termites (dampwood, drywood, subterranean) are endemic to the country, with over 360 classified 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. [195] Epigeal nests (mounds) protrude from the earth with ground contact and are made out of earth and mud. In the eusocial Hymenoptera, the workers are exclusively female. [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. [30] Other studies suggest that the origin of termites is more recent, having diverged from Cryptocercus sometime during the Early Cretaceous. Termites collected from the field could be tested for the rabbit-IgG markers using a rabbit-IgG-specific assay. Aphids secrete honeydew as they feed, which attracts ants and causes a black sooty mold to grow on the leaves. The worker termites and the male termites do not live so long. Serritermitidae Pill bugs and sow bugs are generally herbivores, feeding on the fungi and bacteria that infest dead and rotting vegetation. The beetles bore into the wood to lay eggs. [103], Some species of termite practice fungiculture. [167] Similarly, Formosan subterranean termites have been known to secrete naphthalene to protect their nests. [17] Termites are thought to be the descendants of the genus Cryptocercus. 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). Millipedes, such as the one shown here, as well as centipedes are known as myriapods. The time when nuptial flight begins depends on the environmental conditions, the time of day, moisture, wind speed and precipitation. These fights can cause mortality on both sides and, in some cases, the gain or loss of territory. 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. [61] Many soldiers have large heads with highly modified powerful jaws so enlarged they cannot feed themselves. This Queen termite lives for about 50 to 70 yrs if it is left safe in its mound. 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. [157] Ants such as Megaponera analis attack the outside of mounds and Dorylinae ants attack underground. Wood Infesting Insects. [148], Competition between two colonies always results in agonistic behaviour towards each other, resulting in fights. [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. About 3,106 species are currently described, with a few hundred more left to be described. [39], Due to their soft cuticles, termites do not inhabit cool or cold habitats.

For example, the intromittent organ is not present in male alates, and the sperm is either immotile or aflagellate. [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. The beetles share the same cuticle hydrocarbons as the termites and even biosynthesize them. This variety of beetle is attracted to dying or freshly cut trees. [211] Their habit of remaining concealed often results in their presence being undetected until the timbers are severely damaged, with only a thin exterior layer of wood remaining, which protects them from the environment. The temperature then remains at a plateau for the rest of the day until the evening. [203] A highly protected chamber, known as the "queens cell", houses the queen and king and is used as a last line of defence. [219], To better control the population of termites, various methods have been developed to track termite movements. [241], This article is about social insects. [159][160] Each colony has its own distinct odour. Termites are infected by viruses including Entomopoxvirinae and the Nuclear Polyhedrosis Virus. Like ants and some bees and wasps from the separate order Hymenoptera, termites divide as "workers" and "soldiers" that are usually sterile.
