Subterranean termites construct tunnels and galleries to look for food, and workers who manage to find food sources recruit additional nestmates by depositing a phagostimulant pheromone that attracts workers. They vary from 0.25 to 3 inches in length. 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.  It is only relatively recently, however, that climate responsive construction techniques have become incorporated into modern architecture. † Cratomastotermitidae 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. Approximately 1.1 million active termite mounds can be found in the northern Kruger National Park alone. Old house borers. Cockroaches are generalized insects, with few special adaptations, and may be among the most primitive living Neopteran insects. These beetles grow to 1/2 to 1 inch long and only attack softwoods, primarily pine.  The alates (winged males and females) have eyes along with lateral ocelli. , 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. , The Eastgate Centre is a shopping centre and office block in central Harare, Zimbabwe, whose architect, Mick Pearce, used passive cooling inspired by that used by the local termites. Termites. Kiwi . The alates fly only for a brief amount of time, so they also rely on their legs. A new species of stick insect in southern China has been declared the world's longest bug, state media announced on Thursday. Termite antennae have a number of functions such as the sensing of touch, taste, odours (including pheromones), heat and vibration. For example, the intromittent organ is not present in male alates, and the sperm is either immotile or aflagellate. † Archeorhinotermitidae Yet, some insects live comparatively really long lives. Dampwood termites are found only in coniferous forests, and drywood termites are found in hardwood forests; subterranean termites live in widely diverse areas. Pill bugs are less than an inch long.  Termites can be beneficial to agriculture, such as by boosting crop yields and enriching the soil. Some species of termite, including Nasutitermes corniger, form associations with certain ant species to keep away predatory ant species.  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). 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. Termites mostly feed on dead plant material and cellulose, generally in the form of wood, leaf litter, soil, or animal dung. Termites hatch without these symbionts present in their guts, and develop them after fed a culture from other termites.  Termites may attack trees whose resistance to damage is low but generally ignore fast-growing plants. Cellulose digestion in "higher termites" has co-evolved with eukaryotic gut microbiota and many genera have symbiotic relationships with fungi such as Termitomyces; in contrast, "lower termites" typically have flagellates and prokaryotes in their hindguts. Arboreal termites nests can account for as much as 2% of above ground carbon storage in Puerto Rican mangrove swamps. These shelter tubes can be found on walls and other structures. They are reddish-brown to black in color and can grow up to 3/4” long and can be a … For example, F. M. Weesner indicated that the Mastotermitidae termites may go back to the Late Permian, 251 million years ago, and fossil wings that have a close resemblance to the wings of Mastotermes of the Mastotermitidae, the most primitive living termite, have been discovered in the Permian layers in Kansas. Termites are major detritivores, particularly in the subtropical and tropical regions, and their recycling of wood and plant matter is of considerable ecological importance. They look something like haystacks, but more solid, like stone. , Many plants have developed effective defences against termites.  If an invasion carried out by Megaponera analis is successful, an entire colony may be destroyed, although this scenario is rare. The third phase is marked by a decrease in the number of soldiers present and an increase in the number of workers. In the second phase, workers appear in large numbers at the site. Some of these include dipteran flies, Pyemotes mites, and a large number of nematode parasites.  As the queen and king are monogamous, sperm competition does not occur. , A species of fungus is known to mimic termite eggs, successfully avoiding its natural predators. Some termite species may rely on nymphs to perform work without differentiating as a separate caste. , Foraging behaviour depends on the type of termite. behavioral responses depend on the nature of the carcasses", "Termite-egg mimicry by a sclerotium-forming fungus", "The First Ant-Termite Syninclusion in Amber with CT-Scan Analysis of Taphonomy", "Orchid Pollination: exploring a fascinating world", "Trophic interactions among invertebrates in termitaria in the African savanna: a stable isotope approach", "Degradation of mangrove tissues by arboreal termites (, "Some Consequences of the Shape and Orientation of 'magnetic' Termite Mounds", "New Assay Helps Track Termites, Other Insects", "Economically important termites in the United States and their control", "Edible and medicinal termites: a global overview", "Entomophagy: A key to space agriculture", "Termites as pests of crops, forestry, rangeland and structures in Southern Africa and their control", "Landform development and bioturbation on the Khorat plateau, Northeast Thailand", "Ants and termites increase crop yield in a dry climate", "Termites' gut reaction set for biofuels", "Termite Power: Can Pests' Guts Create New Fuel?  Termites are widely used in traditional popular medicine; they are used as treatments for diseases and other conditions such as asthma, bronchitis, hoarseness, influenza, sinusitis, tonsillitis and whooping cough. Long Finned Eel. This happened in September 2008, when thousands of male termites left their mound each night, died, and covered the floors and water pits of the house holding their exhibit. Especially in Africa, the stack effect has become a popular means to achieve natural ventilation and passive cooling in modern buildings. Termites collected from the field could be tested for the rabbit-IgG markers using a rabbit-IgG-specific assay. What is the longest living insect?  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.  Most of the time, the alates are poor flyers; their technique is to launch themselves in the air and fly in a random direction.  These passageways are made from soil and faeces and are normally brown in colour.  It has been proposed that the Isoptera and Cryptocercidae be grouped in the clade "Xylophagodea". Millipedes, such as the one shown here, as well as centipedes are known as myriapods. Hodotermitidae  As a result, certain beetles and flies have evolved with their hosts.  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. Sterile workers are sometimes termed as true workers while those that are fertile, as in the wood-nesting Archotermopsidae, are termed as false workers. Termites can destroy support beams and while they cannot harm concrete or brick foundations, wood supports that are buried in the earth may be vulnerable. Trophallaxis is an effective nutritional tactic to convert and recycle nitrogenous components. This is one of the most common pests that are found in log homes. The result is a self-organised process whereby the information that directs termite activity results from changes in the environment rather than from direct contact among individuals. 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. Dampwood termites only attack lumber material exposed to rainfall or soil. One of the few that do, the Zoo Basel in Switzerland, has two thriving Macrotermes bellicosus populations – resulting in an event very rare in captivity: the mass migrations of young flying termites. This Queen termite lives for about 50 to 70 yrs if it is left safe in its mound. As wood is difficult to digest, termites prefer to consume fungus-infected wood because it is easier to digest and the fungi are high in protein. , Certain species such as Gnathamitermes tubiformans have seasonal food habits. Other such buildings include the Learning Resource Center at the Catholic University of Eastern Africa and the Council House 2 building in Melbourne, Australia.  There are ten tergites, of which nine are wide and one is elongated.  These unique soldiers are able to spray noxious, sticky secretions containing diterpenes at their enemies. The termite adds these objects onto existing structures, and such behaviour encourages building behaviour in other workers.  Nymphs first moult into workers, and then some workers go through further moulting and become soldiers or alates; workers become alates only by moulting into alate nymphs. Their colonies range in size from a few hundred individuals to enormous societies with several million individuals.  Less than 10% of drywood termites are pests, but they infect wooden structures and furniture in tropical, subtropical and other regions. Ambrosia beetles damage hardwoods and softwoods The pin holes up to 1 ⁄ 8 " in diameter often seen in oak and other woods are signs left by the ambrosia beetle or other anobiid beetles. Beetles are the most common group found developing in firewood. , This article is about social insects. 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. Rhinotermitidae However, some species, such as Hodotermes mossambicus, have compound eyes which they use for orientation and to distinguish sunlight from moonlight. , The soldier caste has anatomical and behavioural specialisations, and their sole purpose is to defend the colony. Peacock .  A nest has many functions such as providing a protected living space and providing shelter against predators. If termites are not controlled, damage will continue to accrue. termites, both subterranean termitesand drywood termites, carpenter antsand certain powderpost beetlesare the primary insects that can destroy wood.  In 2008 DNA analysis from 16S rRNA sequences supported the position of termites being nested within the evolutionary tree containing the order Blattodea, which included the cockroaches.  Each colony has its own distinct odour. , African tribes in several countries have termites as totems, and for this reason tribe members are forbidden to eat the reproductive alates.  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). 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 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.  Constructed by termites during the night, a time of higher humidity, these tubes provide protection to termites from potential predators, especially ants.  Termite alates are high in nutrition with adequate levels of fat and protein.  Certain species of ants in the subfamily Ponerinae conduct these raids although other ant species go in alone to steal the eggs or nymphs.  Termites are sometimes called "white ants" but the only resemblance to the ants is due to their sociality which is due to convergent evolution with termites being the first social insects to evolve a caste system more than 100 million years ago.  It was the first major building exploiting termite-inspired cooling techniques to attract international attention. Horntails. , Species in the genus Macrotermes arguably build the most complex structures in the insect world, constructing enormous mounds.  The appearance of the legs is similar in each caste, but the soldiers have larger and heavier legs. Also known as Buprestidae and part of the jewel beetle family, this beetle has quite the lifespan, though not all of it is productive. When termites detect a potential breach, the soldiers usually bang their heads, apparently to attract other soldiers for defence and to recruit additional workers to repair any breach. , Owing to their wood-eating habits, many termite species can do significant damage to unprotected buildings and other wooden structures. , 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.  Nests made out of carton are particularly weak, and so the inhabitants use counter-attack strategies against invading predators. , The development of nymphs into adults can take months; the time period depends on food availability, temperature, and the general population of the colony. Termites are less likely to be attacked by parasites than bees, wasps and ants, as they are usually well protected in their mounds. For example, though they might block each other's passages, colonies of Macrotermes bellicosus and Macrotermes subhyalinus are not always aggressive towards each other. The lower termites predominately feed on wood. Most termites construct underground colonies rather than multifunctional nests and mounds.  Of the 3,106 species known, only 183 species cause damage; 83 species cause significant damage to wooden structures. Colonies are described as superorganisms because the termites form part of a self-regulating entity: the colony itself.. This chemical mimicry allows the beetles to integrate themselves within the termite colonies.  One species in the drywood group is the West Indian drywood termite (Cryptotermes brevis), which is an invasive species in Australia. ", "Termites Green Architecture in the Tropics", "Termites and human society in Southeast Asia", Jared Leadbetter seminar: Termites and Their Symbiotic Gut Microbes, https://en.wikipedia.org/w/index.php?title=Termite&oldid=991899240, Pages containing links to subscription-only content, Creative Commons Attribution-ShareAlike License, This page was last edited on 2 December 2020, at 11:37. , Termites are known to carry pollen and regularly visit flowers, so are regarded as potential pollinators for a number of flowering plants.  Similarly, Formosan subterranean termites have been known to secrete naphthalene to protect their nests.  A mound provides termites the same protection as a nest but is stronger.  Many soldiers have large heads with highly modified powerful jaws so enlarged they cannot feed themselves. , Consistent with all insects, the anatomy of the termite thorax consists of three segments: the prothorax, the mesothorax and the metathorax. 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.  Another termite species, Amitermes meridionalis, can build nests 3 to 4 metres (9 to 13 feet) high and 2.5 metres (8 feet) wide. However, Mastotermitidae termites have multiflagellate sperm with limited motility.  Through the action of unidentified enzymes in the termite gut, lignocellulose polymers are broken down into sugars and are transformed into hydrogen. 5. , Termites are consumed by people in many different cultures around the world.  In the 1960s additional evidence supporting that hypothesis emerged when F. A. McKittrick noted similar morphological characteristics between some termites and Cryptocercus nymphs. Polycalic species of termites form multiple nests, or calies, connected by subterranean chambers. , Few zoos hold termites, due to the difficulty in keeping them captive and to the reluctance of authorities to permit potential pests. 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. Bostrichid Powderpost Beetle The larvae of Bostrichid beetles live and feed in wood. 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. Serritermitidae  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. , Arboreal carton nests of mangrove swamp-dwelling Nasutitermes are enriched in lignin and depleted in cellulose and xylans.  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; transmission usually occurs via direct physical contact. The insect group that they belong to … The beetles share the same cuticle hydrocarbons as the termites and even biosynthesize them. These termites are known in part for the large mounds they build. Insects have been here on Earth long before humans, and they are here to stay. The best result comes when they are lightly roasted on a hot plate or fried until crisp. , Termites are consumed by a wide variety of predators. Red Sea Urchin. , 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. The beetles bore into the wood to lay eggs. For example, alates in certain species emerge during the day in summer while others emerge during the winter. Within China, termite species are restricted to mild tropical and subtropical habitats south of the Yangtze River.  In one species, Nasutitermes costalis, there are three phases in a foraging expedition: first, soldiers scout an area.  In North America, 18 subterranean species are pests; in Australia, 16 species have an economic impact; in the Indian subcontinent 26 species are considered pests, and in tropical Africa, 24. , Most termites are blind, so communication primarily occurs through chemical, mechanical and pheromonal cues.  Mounds located in areas with torrential and continuous rainfall are at risk of mound erosion due to their clay-rich construction. , 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).  Other studies suggest that the origin of termites is more recent, having diverged from Cryptocercus sometime during the Early Cretaceous.  Nymphs resemble small adults, and go through a series of moults as they grow. No single termite would be in charge of any particular construction project. , Worker termites undertake the most labour within the colony, being responsible for foraging, food storage, and brood and nest maintenance.  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.  Among the termite genera, Coptotermes has the highest number of pest species of any genus, with 28 species known to cause damage. The flagellates have been lost in Termitidae. ; Body Carpenter ants have six legs and a single, narrow segment connects a bulbous abdomen and a smooth, evenly-rounded thorax.  The largest of all extant termites are the queens of the species Macrotermes bellicosus, measuring up to over 10 centimetres (4 in) in length. 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. , 54 species of ants are known to inhabit Nasutitermes mounds, both occupied and abandoned ones. For example, they may preferentially consume Red three-awn (Aristida longiseta) during the summer, Buffalograss (Buchloe dactyloides) from May to August, and blue grama Bouteloua gracilis during spring, summer and autumn. The phrase longest-living insect is a little ambiguous. Longest-Living Insects.  Many species are readily identified using the characteristics of the soldiers' larger and darker head and large mandibles. The size of these shelter tubes depends on the number of food sources that are available.  Shelter tubes also provide high humidity and darkness and allow workers to collect food sources that cannot be accessed in any other way. Termites are among the most successful groups of insects on Earth, colonising most landmasses except Antarctica. Termite colonies generally take around 3 to 5 years to reach maturity.  Researchers have suggested that termites are suitable candidates for human consumption and space agriculture, as they are high in protein and can be used to convert inedible waste to consumable products for humans. After a female deposits eggs on a host tree, the larva hatch and tunnel into the wood where they can stay for 25 to 30 years. In particular, ants that prey on termites usually have a negative impact on arboreal nesting species. Many phasmids, however, have been in culture a long time and many people have them, despite the regulations. Moisture and wet wood will attract pests like pillbugs , house centipedes , cockroaches , earwigs , and even ladybugs , so it’s important to keep the wood off the ground. , To better control the population of termites, various methods have been developed to track termite movements.  Possible evidence of a Jurassic origin is the assumption that the extinct Fruitafossor consumed termites, judging from its morphological similarity to modern termite-eating mammals. The longest living insects are the Splendour beetles (Buprestidae), some of which remain in the larva stage for more than 30 years. , In addition to causing damage to buildings, termites can also damage food crops. Identification. Termitidae. , Some species of termite practice fungiculture. Many sphecoid wasps and several species including Polybia and Angiopolybia are known to raid termite mounds during the termites' nuptial flight.. A black flying insect that burrows into wood is the carpenter bee.  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. They also play a vital role in the ecosystem by recycling waste material such as dead wood, faeces and plants. For example, certain species feed on the wood structures they inhabit, and others harvest food that is near the nest. The potential for damage from any of One thing's for sure, she's not lying around watching television all those long years. Instead, like juveniles, they are fed by workers. Termites are a delicacy in the diet of some human cultures and are used in many traditional medicines. 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). , Alates are collected when the rainy season begins. Termite populations can be substantially impacted by environmental changes including those caused by human intervention.  The nuptial flight may also begin at dusk, when the alates swarm around areas with many lights. , Termites have a ten-segmented abdomen with two plates, the tergites and the sternites. Termites and ants can re-colonise untilled land that contains crop stubble, which colonies use for nourishment when they establish their nests. Once they have established themselves they can do considerable damage in a short period of time. The wood-feeders were the most severely affected feeding group. In one study, the drywood termite Cryptotermes brevis strongly preferred poplar and maple woods to other woods that were generally rejected by the termite colony. Like ants and some bees and wasps from the separate order Hymenoptera, termites divide as "workers" and "soldiers" that are usually sterile. Since nymphs are unable to feed themselves, workers must feed them, but workers also take part in the social life of the colony and have certain other tasks to accomplish such as foraging, building or maintaining the nest or tending to the queen.  Suicide cramming is known in Coptotermes formosanus.  Termites are considered to be a major source (11%) of atmospheric methane, one of the prime greenhouse gases, produced from the breakdown of cellulose. Trail pheromones are secreted from the sternal gland, and sex pheromones derive from two glandular sources: the sternal and tergal glands.
