bean weevils
seed beetles
bruchinae latin

Bean weevils are generally compact and oval in shape, with small heads somewhat bent under.

This morphology may have been an evolutionary defense against seed predators such as bean weevils (Bruchinae).

For example, male bean weevils (Callosobruchus maculatus) have spiny genitalia.

Acanthoscelides is a genus of bean weevils.

In 1922 he received a PhD from the University of Cape Town for his research on bean weevils or Bruchids.

The bean weevils or seed beetles are a subfamily (Bruchinae) of beetles, now placed in the family Chrysomelidae, though they have historically been treated as a separate family.

They found the protein arcelin, at about the same time that researchers at the Centro Internacional de Agricultura Tropical (CIAT) of Cali, Colombia, published their discovery of wild beans that resist bean weevils.

In seed beetles, populations differed in development time and growth rate between sexes.

In seed beetles (Coleoptera: Bruchidae), males possess sclerotized spines on their genitalia.

Male seed beetles (Coleoptera: Bruchidae) have sclerotized spine on their genitalia, which penetrate the female and leave melanized scars.

The bean weevils or seed beetles are a subfamily (Bruchinae) of beetles, now placed in the family Chrysomelidae, though they have historically been treated as a separate family.

In seed beetles, a positive correlation exists between the degree of harmfulness of the male's genitalia and the thickness or reinforcement of the wall of the bursa copulatrix in the female's reproductive tract.

Stator is a genus of Bruchinae.

Spermophagus is a genus of beetles belonging to the family Chrysomelidae subfamily Bruchinae.

In those days they were regarded as comprising the family Bruchidae, though currently they are classified as the subfamily Bruchinae of the family Chrysomelidae.

While most members of the beetle subfamily Bruchinae (sometimes called the "pea and bean weevils") feed on legumes, Caryobruchus and its relatives in the tribe Pachymerini feed on palm trees and are known as "palm seed weevils".

Other beetles with spectacularly muscular hind femora may not be saltatorial at all, but very clumsy; for example, particular species of Bruchinae use their swollen hind legs for forcing their way out of the hard-shelled seeds of plants such as Erythrina in which they grew to adulthood.
