Prorhinotermes Simplex
''Prorhinotermes simplex'', the Cuban subterranean termite, is a species of lower termite in the genus ''Prorhinotermes''. It is found in Colombia. Like others in its genus, it is a single-site nesting termite that moves to a new food source when theirs is gone, and it lacks a true worker caste. Caste Like all other members of ''Prorhinotermes'', ''P. simplex'' lacks a true worker caste (meaning permanently sterile workers) and has a linear ontogenetical pathway with a single Nymph (biology), nymphal instar. Soldiers typically arise from the late larval stage in mature colonies and can be identified from their marked wing rudiments. Each of their two molts from larva to soldier adds an antennae segment, and they contain a lot of the chemicals (E)-1-nitropentadec-1-ene, (E)-1-nitropentadecene and (''Z'',''E'')-α-Farnesene. They make up from 7-22% of each colony's population. They typically guard inside the nest, but they will come out as defenders if the nest is moved. Soldiers ...

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 ...

Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments and the Capital District of Bogotá, the country's largest city. It covers an area of 1,141,748 square kilometers (440,831 sq mi), and has a population of 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Amerindian civilizations that predate colonization.

Ontogenetic
Ontogeny (also ontogenesis) is the origination and development of an organism (both physical and psychological, e.g., moral development), usually from the time of fertilization of the egg to adult. The term can also be used to refer to the study of the entirety of an organism's lifespan. Ontogeny is the developmental history of an organism within its own lifetime, as distinct from phylogeny, which refers to the evolutionary history of a species. Another way to think of ontogeny is that it is the process of an organism going through all of the developmental stages over its lifetime. The developmental history includes all the developmental events that occur during the existence of an organism, beginning with the changes in the egg at the time of fertilization and events from the time of birth or hatching and afterward (i.e., growth, remolding of body shape, development of secondary sexual characteristics, etc.). While developmental (i.e., ontogenetic) processes can influence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nymph (biology)
In biology, a nymph is the immature form of some invertebrates, particularly insects, which undergoes gradual metamorphosis ( hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph's overall form already resembles that of the adult, except for a lack of wings (in winged species). In addition, while a nymph moults, it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars. This is the case, for example, in Orthoptera ( crickets, grasshoppers and locusts), Hemiptera (cicadas, shield bugs, whiteflies, aphids, leafhoppers, froghoppers, treehoppers etc.), mayflies, termites, cockroaches, mantises, stoneflies and Odonata ( dragonflies and damselflies). Nymphs of aquatic insects, as in the Odonata, Ephemeroptera, and Plecoptera, are also called naiads, an Ancient Greek name for mythological water nymphs. Usage of the term 'naiad' is no longer popular among en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal ...

(E)-1-nitropentadec-1-ene
Nitropentadecene, or more precisely (''E'')-1-nitropentadec-1-ene, is a highly toxic unsaturated nitroalkene, the only aliphatic nitro compound known to be synthesized by insects. It is produced by termite soldiers of genus ''Prorhinotermes'' (Isoptera, Rhinotermitidae Rhinotermitidae is a family of termites (Isoptera). They feed on wood and can cause extensive damage to buildings or other wooden structures. About 345 species are recognized, among these are severe pests such as '' Coptotermes formosanus'', ''Co ...) as a defensive chemical. Nitropentadecene is biosynthesized and stored in one of the exocrine glands, a frontal gland, of termite soldiers, and it is released upon attack of enemy.

Farnesene
The term farnesene refers to a set of six closely related chemical compounds which all are sesquiterpenes. α-Farnesene and β-farnesene are isomers, differing by the location of one double bond. α-Farnesene is 3,7,11-trimethyl-1,3,6,10-dodecatetraene and β-farnesene is 7,11-dimethyl-3-methylene-1,6,10-dodecatriene. The alpha form can exist as four stereoisomers that differ about the geometry of two of its three internal double bonds (the stereoisomers of the third internal double bond are identical). The beta isomer exists as two stereoisomers about the geometry of its central double bond. Two of the α-farnesene stereoisomers are reported to occur in nature. (''E'',''E'')-α-Farnesene is the most common isomer. It is found in the coating of apples, and other fruits, and it is responsible for the characteristic green apple odour. Its oxidation by air forms compounds that are damaging to the fruit. The oxidation products injure cell membranes which eventually causes cell dea ...

Cthulhu Macrofasciculumque
''Cthulhu macrofasciculumque'' is a species of excavates. It lives in the guts of termites. Habitat It lives in the hindgut of ''Prorhinotermes simplex'' (Cuban subterranean termite) and helps them to digest wood. Appearance The microbe's length is about a fifth of the width of a human hair, in the range of 10 to 20 µm, and it has around 20 flagella. ''Cthylla'' is slightly smaller, with only five flagella. Naming The octopus-like movements and appearance of ''Cthulhu macrofasciculumque'' (as well as another protist that assists in the digestion of wood by termites) reminded researcher Erick James of Cthulhu, H. P. Lovecraft's fictional cosmic entity. James named the other protist, ''Cthylla microfasciculumque'', after Cthulhu's "daughter" Cthylla. See also *Eastern subterranean termite ''Reticulitermes flavipes'', the eastern subterranean termite, is the most common termite found in North America.

Cthulhu
Cthulhu is a fictional cosmic entity created by writer H. P. Lovecraft. It was first introduced in his short story "The Call of Cthulhu", published by the American pulp magazine ''Weird Tales'' in 1928. Considered a Great Old One within the pantheon of Lovecraftian cosmic entities, this creature has since been featured in numerous popular culture references. Lovecraft depicts it as a gigantic entity worshipped by cultists, in the shape of a green octopus, dragon, and a caricature of human form. The Lovecraft-inspired universe, the Cthulhu Mythos, where it exists with its fellow entities, is named after it. Etymology, spelling, and pronunciation Invented by Lovecraft in 1928, the name Cthulhu was probably chosen to echo the word ''chthonic'' (Ancient Greek "of the earth"), as apparently suggested by Lovecraft himself at the end of his 1923 tale "The Rats in the Walls". The chthonic, or earth-dwelling, spirit has precedents in numerous ancient and medieval mythologies, often guard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digestion Of Wood
Xylophagy is a term used in ecology to describe the habits of an herbivorous animal whose diet consists primarily (often solely) of wood. The word derives from Greek ''ξυλοφάγος'' (''xulophagos'') "eating wood", from ''ξύλον'' (') "wood" and ''φαγεῖν'' (') "to eat", an ancient Greek name for a kind of a worm-eating bird. Animals feeding only on dead wood are called sapro-xylophagous or saproxylic. Xylophagous insects Most such animals are arthropods, primarily insects of various kinds, in which the behavior is quite common, and found in many different orders. It is not uncommon for insects to specialize to various degrees; in some cases, they limit themselves to certain plant groups (a taxonomic specialization), and in others, it is the physical characteristics of the wood itself (e.g., state of decay, hardness, whether the wood is alive or dead, or the choice of heartwood versus sapwood versus bark). Many xylophagous insects have symbiotic protozoa and/o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
