Anthonomus Chaos
''Anthonomus'' is a genus of weevils. This genus includes major agricultural pests such as the boll weevil, strawberry blossom weevil, and pepper weevil, as well as promising biological pest control agents such as ''Anthonomus santacruzi''. Taxonomy The taxonomy of the genus is still under revision. It is unclear whether '' Cnemocyllus'' should be a genus or a subgenus within ''Anthonomus''. Research suggests that the genus '' Hampea'' in the mallow family was the original host plant for the ''A. grandis'' species group.

Anthonomus Grandis
The boll weevil (''Anthonomus grandis'') is a beetle that feeds on cotton buds and flowers. Thought to be native to Central Mexico, it migrated into the United States from Mexico in the late 19th century and had infested all U.S. cotton-growing areas by the 1920s, devastating the industry and the people working in the American South. During the late 20th century, it became a serious pest in South America as well. Since 1978, the Boll Weevil Eradication Program in the U.S. allowed full-scale cultivation to resume in many regions. Description The adult insect has a long snout, a grayish color, and is usually less than in length. Lifecycle 1) Back view of adult; 2) side view of adult; 3) egg; 4) side view of larva; 5) ventral view of pupa; 6) adult, with wings spread Adult weevils overwinter in well-drained areas in or near cotton fields, and farms after diapause. They emerge and enter cotton fields from early spring through midsummer, with peak emergence in late spring, and fee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |

Anthonomus Rubi
''Anthonomus rubi'', the strawberry-blossom weevil or strawberry blossom weevil, is a species of weevil found in Europe and western Asia. It feeds on plants of the family Rosaceae and is an important pest of strawberry (''Fragaria'' × ''ananassa'' Duchesne) and raspberry (''Rubus idaeus'' L.). This insect is a particularly problematic pest of strawberry in Europe, in some cases responsible for up to 80% loss of the berry crop. Ecology and description Adults are long and dull black, covered with a fine grey pubescence. The larvae are long, curved, and white with brown head. Adults feed on strawberry foliage, and females lay eggs inside unopened flower buds (one egg per bud) before partially or totally severing the stalk; larvae develop inside the severed buds, feeding on the wilting tissue. Role of pheromones Adults are thought to be attracted to strawberries by chemicals released by the plants. Monoterpenes, sesquiterpenes, and aromatic compounds acted as odorants (attracto ...

Anthonomus Eugenii
''Anthonomus eugenii'' is known as the pepper weevil. This beetle feeds and lays eggs on plants in the genus ''Capsicum'' and a few species in the genus '' Solanum''. ''A. eugenii'' is native to Mexico, however, it is an important pest of ''Capsicum'' in Florida, Puerto Rico, and Central America. Identification Adult ''A. eugenii'' are dark brown in colour with cream coloured scales covering their bodies. They are approximately 3 millimetres in length and have an oval-shaped body. ''A. eugenii'' have a curved rostrum, which is characteristic of the genus ''Anthonomus''. Female ''A. eugenii'' have a greater length between the antennae and mandibles on the rostrum, which is thought to aid in burrowing into host plants for oviposition. Distribution ''A. eugenii'' are predominately found throughout Mexico, Central America, the Caribbean, and the southernmost states of the United States of America. The northern range of ''A. eugenii'' is limited by cold temperatures and the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Anthonomus Santacruzi
''Anthonomus santacruzi'' is a weevil that is a promising biocontrol agent for ''Solanum mauritianum'' Scopoli, which is a major ecological weed in high-rainfall regions of South Africa. The weevil exhibited a preference for ''S. mauritianum'' and possibly two South African native species of ''Solanum'', namely ''Solanum linnaeanum, S. linnaeanum'' and ''S. tomentosum''.

Malvaceae
Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao and durian. There are also some genera containing familiar ornamentals, such as ''Alcea'' (hollyhock), ''Malva'' (mallow), and ''Tilia'' (lime or linden tree). The largest genera in terms of number of species include ''Hibiscus'' (300 species), ''Sterculia'' (250 species), ''Dombeya'' (250 species), '' Pavonia'' (200 species) and '' Sida'' (200 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae '' sensu stricto'' comprise a very homogeneous and cladistically monophyletic group. Another major circumscription, Malvaceae ''sensu lato'', has been more recently defined on the basis that genetics studies have shown the commonly recognised families Bombacaceae, Tiliaceae, and Sterculiaceae, which have always been considered closely allie ...
