Assessing common bean genotypes for resistance to (Coleoptera: Chrysomelidae).

(Germar) (Coleoptera: Chrysomelidae) is a major pest of common bean ( L.; Fabales: Fabaceae), and adults can defoliate plants during the whole crop cycle. This study was conducted to evaluate the resistance to in 16 common bean genotypes (14 landraces and 2 cultivars), through three different experiments.

Biological aspects and mating behavior of Leucothyreus albopilosus (Coleoptera: Scarabaeidae).

The genus Leucothyreus has been linked to some commercial plant crop pests. Eventhough several species have been described for this genus, information about this group is still scarce. This study investigated some biological aspects and mating behavior in Leucothyreus albopilosus.

Sexual dimorphism and mating behavior in Anomala testaceipennis.

The beetle, Anomala testaceipennis Blanchard (Coleoptera: Scarabaeidae), occurs in central-western Brazil where larvae feed on the roots of plants causing damage. This research aimed to study sexual dimorphism and mating behavior of A. testaceipennis.
