Gonipterinae
Gonipterini is a tribe (biology), tribe of weevils in the subfamily Curculioninae. The larvae and adults are usually found on eucalyptus trees, where they feed upon the foliage. The larvae are legless and slug-like in appearance. The adults have a broad body, and short stout rostrum. ''Gonipterus gibberus'' and ''Gonipterus scutellatus'' (eucalyptus weevil) were introduced from Australia to South America, where they became pest species in eucalypt plantations. Control of ''Gonipterus'' in South America was largely achieved following the introduction from Australia of a small parasitic wasp that attacks the weevil's eggs, providing an example of biological control.

Weevil
Weevils are beetles belonging to the Taxonomic rank, superfamily Curculionoidea, known for their elongated snouts. They are usually small, less than in length, and Herbivore, herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae (the true weevils). It also includes Bark beetle, bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the Drugstore beetle, biscuit weevil (''Stegobium paniceum''), which belongs to the family Ptinidae. Many weevils are considered pests because of their ability to damage and kill crops. The grain or wheat weevil (''Sitophilus granarius'') damages stored cereal, grain, as does the maize weevil (''Sitophilus zeamais'') among others. The boll weevil (''Anthonomus grandis'') attacks cotton crops; it lays its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gonipterus Gibberus
''Gonipterus gibberus'' is a species of weevil in the family Curculionidae. It is commonly known as the eucalyptus snout beetle, the eucalyptus weevil or the gum tree weevil. It feeds and breeds on ''Eucalyptus'' trees and is endemic to Australia.European and Mediterranean Plant Protection Organization. Data sheets on quarantine pests''Gonipterus gibberus'' and ''Gonipterus scutellatus'' Description This weevil is greyish-brown with a light coloured transverse band. It is about thirteen millimetres long and not readily distinguishable from the closely related weevil, '' Gonipterus scutellatus'', which shares the same common names. The larvae are yellowish-green with dark markings and no green stripes on the abdomen, which distinguishes them from larvae of ''G. scutellatus''. Host plants ''Eucalyptus'' trees are the only hosts for the gum tree weevil.

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological 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] |
South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grow ...

Curculioninae
The beetle subfamily Curculioninae is part of the weevil family Curculionidae. It contains over 23,500 described species in 2,200 genera, and is therefore the largest weevil subfamily. Given that the beetle order (Coleoptera) contains about one-quarter of all known organisms, the Curculioninae represent one of the – if not ''the'' – most successful radiations of terrestrial Metazoa. Many weevils of this group are commonly known as flower weevils or acorn and nut weevils, after a food commonly eaten by Curculioninae larvae and imagines — the reproductive organs of plants. Systematics This large subfamily is divided into around 30 tribes. Delimitation of the Curculioninae is fairly robust considering its enormous size; there is some dispute, however, in their exact boundary with the Molytinae. The Phrynixini and Trypetidini are also included in the Curculioninae by some authors, but more often they are considered Molytinae; conversely, the Itini are usuall ...
