Odontotermes Formosanus
''Odontotermes formosanus'' is a species of fungus-growing termite in the family Termitidae. It is native to southeastern Asia and was first described from Taiwan (then called ''Formosa''). This termite cultivates a symbiotic fungus in a special chamber in the nest. Workers and soldiers gather vegetable detritus which they bring back to the colony, chewing the material to a pulp to make a suitable substrate on which to grow the fungus. Distribution and habitat ''Odontotermes formosanus'' has a widespread distribution in southeastern Asia, its range including Japan, Taiwan, China, Vietnam, Thailand, Myanmar and India. It is a common subterranean species and is a pest of forests, plantations and crops. It also forms nests in earthen dams, and can cause dams and dykes to collapse, as well as doing damage to the pipework. It should not be confused with the worldwide invasive species ''Coptotermes formosanus''. The colony A colony of ''Odontotermes formosanus'' consists of a numbe ...

Termite
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood eating cockroaches of the genus ''Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees a ...

Termitidae
Termitidae is the largest family of termites whose members are commonly known as the higher termites. They are evolutionarily the most specialised termite group, with their highly compartmentalized hindgut lacking the flagellated protozoans common to "lower termites". Whereas lower termites are restricted mostly to woody tissue, higher termites have diverse diets consisting of wood, grass, leaf litter, fungi, lichen, faeces, humus and soil. Subfamilies The family contains the following subfamilies: *Termitidae Latreille, 1802 **Subfamily Apicotermitinae Grassé & Noirot, 1954 955/small> (synonym: Indotermitidae Roonwal & Sen Sarma in Roonwal, 1958) **Subfamily Cubitermitinae Weidner, 1956 **Subfamily Foraminitermitinae Holmgren, 1912 (synonym: Pseudomicrotermitinae Holmgren, 1912) **Subfamily Macrotermitinae Kemner, 1934, nomen protectum CZN 2003/small> (synonyms: Acanthotermitinae Sjöstedt, 1926, nomen rejiciendum CZN 2003/small>; Odontotermitini Weidner, 1956 **Subfamily ...

Taiwan
Taiwan, officially the Republic of China (ROC), is a country in East Asia, at the junction of the East and South China Seas in the northwestern Pacific Ocean, with the People's Republic of China (PRC) to the northwest, Japan to the northeast, and the Philippines to the south. The territories controlled by the ROC consist of 168 islands, with a combined area of . The main island of Taiwan, also known as ''Formosa'', has an area of , with mountain ranges dominating the eastern two-thirds and plains in the western third, where its highly urbanised population is concentrated. The capital, Taipei, forms along with New Taipei City and Keelung the largest metropolitan area of Taiwan. Other major cities include Taoyuan, Taichung, Tainan, and Kaohsiung. With around 23.9 million inhabitants, Taiwan is among the most densely populated countries in the world. Taiwan has been settled for at least 25,000 years. Ancestors of Taiwanese indigenous peoples settled the isla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symbiosis
Symbiosis (from Greek , , "living together", from , , "together", and , bíōsis, "living") is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, must be of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms". The term was subject to a century-long debate about whether it should specifically denote mutualism, as in lichens. Biologists have now abandoned that restriction. Symbiosis can be obligatory, which means that one or more of the symbionts depend on each other for survival, or facultative (optional), when they can generally live independently. Symbiosis is also classified by physical attachment. When symbionts form a single body it is called conjunctive symbiosis, while all other arrangements are called disjunctive symbiosis."symbiosis."

Detritus
In biology, detritus () is dead particulate organic material, as distinguished from dissolved organic material. Detritus typically includes the bodies or fragments of bodies of dead organisms, and fecal material. Detritus typically hosts communities of microorganisms that colonize and decompose (i.e. remineralize) it. In terrestrial ecosystems it is present as leaf litter and other organic matter that is intermixed with soil, which is denominated " soil organic matter". The detritus of aquatic ecosystems is organic material that is suspended in the water and accumulates in depositions on the floor of the body of water; when this floor is a seabed, such a deposition is denominated "marine snow". Theory The corpses of dead plants or animals, material derived from animal tissues (e.g. molted skin), and fecal matter gradually lose their form due to physical processes and the action of decomposers, including grazers, bacteria, and fungi. Decomposition, the process by which or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pest (organism)
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; snake Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales. Ma ...s, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food, beetles, which tunnel into the woodwor ...

Formosan Subterranean Termite
The Formosan termite (''Coptotermes formosanus'') is a species of termite local to southern China and introduced to Taiwan (formerly known as Formosa, where it gets its name), Japan, South Africa, Sri Lanka, Hawaii, and the continental United States. The Formosan termite is often nicknamed the super-termite because of its destructive habits due to the large size of its colonies and its ability to consume wood at a rapid rate. Populations of these termites have become large enough to appear on New Orleans' weather radars. A mature Formosan colony can consume as much as 13 ounces of wood a day (about 400 g) and can severely damage a structure in as little as three months. Formosan termites infest a wide variety of structures (including boats and high-rise condominiums) and can damage trees. In the United States, along with another species, ''Coptotermes gestroi'', introduced from Southeast Asia, they are responsible for tremendous damage to property resulting in large treatment ...

Major Components Of Odontotermes Formosanus Agriculture
Major ( commandant in certain jurisdictions) is a military rank of commissioned officer status, with corresponding ranks existing in many military forces throughout the world. When used unhyphenated and in conjunction with no other indicators, major is one rank above captain, and one rank below lieutenant colonel. It is considered the most junior of the field officer ranks. Background Majors are typically assigned as specialised executive or operations officers for battalion-sized units of 300 to 1,200 soldiers while in some nations, like Germany, majors are often in command of a company. When used in hyphenated or combined fashion, the term can also imply seniority at other levels of rank, including ''general-major'' or ''major general'', denoting a low-level general officer, and '' sergeant major'', denoting the most senior non-commissioned officer (NCO) of a military unit. The term ''major'' can also be used with a hyphen to denote the leader of a military band such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Termitomyces
''Termitomyces'' is a genus of basidiomycete fungi belonging to the family Lyophyllaceae. There are 30-40 species in the genus, all of which are completely dependent on termites to survive. They are the food source for a subfamily of termites, the Macrotermitinae, who enjoy an obligate symbiosis with the genus similar to that between '' Atta'' ants and '' Attamyces'' mushrooms. Despite this relationship, spore transfer is still accomplished mainly by shedding from mushrooms, which protrude from the termite mounds. Characteristics These mushrooms are edible for most people, and the larger species are a popular wild food where they occur. They include the largest edible mushroom in the world, '' Termitomyces titanicus'' of West Africa and Zambia, whose cap reaches 1 metre (3.28ft) in diameter. These fungi grow on 'combs' which are formed from the termites' excreta, dominated by tough woody fragments. ''Termitomyces'' was described by Roger Heim in 1942. From 1955 to 1969 Arthur Fr ...

Substrate (biology)
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives. A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae. Inert substrates are used as growing support materials in the hydroponic cultivation of plants. In biology substrates are often activated by the nanoscopic process of substrate presentation. In agriculture and horticulture * Cellulose substrate * Expanded clay aggregate (LECA) * Rock wool * Potting soil * Soil In animal biotechnology Requirements for animal cell and tissue culture Requirements for animal cell and tissue culture are the same as described for plant cell, tissue and organ culture (In Vitro Culture Techniques: The Biotechnological Principles).
