Bissetia Steniellus
''Bissetia steniellus'' is a moth in the family Crambidae. It was first described by the British entomologist George Hampson in 1899. It is found in India and Vietnam where it is commonly known as the Gurdaspur borer because the larvae bore their way into and feed on the stems of sugarcane. Description The adult ''Bissetia steniellus'' has a wingspan of . It is generally drab brown, and there are seven darker brown spots arranged between the veins on the outer margins of the forewings. The larva is creamy-white with four narrow, longitudinal, reddish stripes along the body, and an orange head. Distribution ''B. steniellus'' is found in India, Pakistan and Vietnam. Its range in India includes the states of Haryana, Punjab, Uttar Pradesh and Rajasthan. Life cycle The only known host plant for ''B. steniellus'' is the sugarcane. The female moth lays a batch of 100 to 300 eggs on the midrib of a sugarcane leaf. The larvae hatch out after about a week and make their way into the st ...

George Hampson
Sir George Francis Hampson, 10th Baronet (14 January 1860 – 15 October 1936) was an English entomologist. Hampson studied at Charterhouse School and Exeter College, Oxford. He travelled to India to become a tea-planter in the Nilgiri Hills of the Madras presidency (now Tamil Nadu), where he became interested in moths and butterflies. When he returned to England he became a voluntary worker at the Natural History Museum, where he wrote ''The Lepidoptera of the Nilgiri District'' (1891) and ''The Lepidoptera Heterocera of Ceylon'' (1893) as parts 8 and 9 of ''Illustrations of Typical Specimens of Lepidoptera Heterocera of the British Museum''. He then commenced work on ''The Fauna of British India, Including Ceylon and Burma: Moths'' (four volumes, 1892–1896). Albert C. L. G. Günther offered him a position as assistant at the museum in March 1895, and, after succeeding to his baronetcy A baronet ( or ; abbreviated Bart or Bt) or the female equivalent, a baronetess (, ...

Organochloride
An organochloride, organochlorine compound, chlorocarbon, or chlorinated hydrocarbon is an organic compound containing at least one covalent bond, covalently bonded atom of chlorine. The chloroalkane class (alkanes with one or more hydrogens substituted by chlorine) provides common examples. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties. Organochlorine compounds have wide use in many applications, though some are of profound environmental concern, with 2,3,7,8-Tetrachlorodibenzodioxin, TCDD being one of the most notorious. Physical and chemical properties Chlorination reaction, Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular dam ...

Agricultural Pest Insects
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; snakes, 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 woodwork, and other animals that scuttle about on the floor at night, like cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being insects, mite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moths Of Asia
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order.

Haimbachiini
Crambinae is a large subfamily of the lepidopteran family Crambidae, the crambid snout moths. It currently includes over 1,800 species worldwide. The larvae are root feeders or stem borers, mostly on grasses. A few species are pests of sod grasses, maize, sugar cane, rice, and other Poaceae. The monophyly of this group is supported by the structure of the tympanal organs and the phallus attached medially to the juxta, as well as genetic analyses. Taxonomists' opinions differ as to the correct placement of the Crambidae, some authorities treating them as a subfamily of the family Pyralidae. If this is done, the present group would be demoted to tribe status, as Crambini.

Biological Pest Control
Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitoid
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host (biology), host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionarily stable strategy, evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation. Among parasitoids, strategies range from living inside the host (''endoparasitism''), allowing it to continue growing before emerging as an adult, to Paralysis, paralysing the host and living outside it (''ectoparasitism''). Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible. Some parasitoids Behavior-altering parasite, influence their host's behaviour in ways that favour the propagation of the parasitoid. Parasitoids are found in a variety of Taxon, taxa across the insect superorder Endopterygota, whose compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sturmiopsis Inferens
''Sturmiopsis inferens'' is a species of fly in the family Tachinidae. It is native to Asia and is a parasitoid of various moth species whose larvae feed inside the stems of sugarcane, rice and other large grasses, including the Gurdaspur borer (''Bissetia steniellus'') and the sugarcane shoot borer (''Chilo infuscatellus'').

Endrin
Endrin is an organochloride with the chemical formula C12H8Cl6O that was first produced in 1950 by Shell and Velsicol Chemical Corporation. It was primarily used as an insecticide, as well as a rodenticide and piscicide. It is a colourless, odorless solid, although commercial samples are often off-white. Endrin was manufactured as an emulsifiable solution known commercially as Endrex. The compound became infamous as a persistent organic pollutant and for this reason it is banned in many countries. In the environment endrin exists as either endrin aldehyde or endrin ketone and can be found mainly in bottom sediments of bodies of water. Exposure to endrin can occur by inhalation, ingestion of substances containing the compound, or skin contact. Upon entering the body, it can be stored in body fats and can act as a neurotoxin on the central nervous system, which can cause convulsions, seizures, or even death. Although endrin is not currently classified as a mutagen, nor as a human c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
