Anthonomus

E.F. Germar, 1817

Anthonomus is a large of () described by Germar in 1817. The genus includes numerous , many of significant economic importance. Several members are major agricultural pests, including the cotton (A. grandis), blossom weevil (A. signatus), and (A. eugenii). Conversely, some species such as A. santacruzi are utilized as agents against . The of the genus remains under revision, particularly regarding the status of Cnemocyllus as either a distinct genus or subgenus.

Identification

-level identification of Anthonomus relies on characters typical of the tribe Anthonomini within Curculioninae. -level identification requires detailed examination of morphological features including the shape of fore and fore , structure of the male , and coloration of body . Some species groups, such as the A. squamosus group, show distinctive rostral scaling patterns with elongate present beyond the point of antennal insertion. The genus is taxonomically complex and identification to species often requires knowledge and reference to original descriptions.

Human Relevance

Anthonomus have substantial economic impact through both negative and positive effects. Several species are major agricultural pests causing significant damage: A. grandis (cotton ) historically devastated cotton production in the Americas; A. signatus ( blossom ) damages strawberry crops; A. eugenii () affects pepper and solanaceous crops. These pests are subject to regulation and measures in multiple countries. Conversely, A. santacruzi has been developed as a agent against , demonstrating the dual agricultural significance of the .
