Anthonomus Eugenii 2510021
''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.

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] |
