Khapra beetle, Trogoderma granarium (Coleoptera: Dermestidae), is among the world’s most invasive and destructive pests of stored agricultural products. Its pest status is enhanced by the ability of the larvae to undergo diapause, which increases their tolerance to adverse conditions including insecticides and extreme temperatures. The ability of insects to tolerate extreme conditions can be influenced...
Wolbachia are intracellular bacteria that infect numerous and diverse arthropod species including economic pests of crops and disease vectors affecting livestock and humans. Research on these symbionts has identified profound effects of Wolbachia on their hosts with possible application in pest control. Such research often requires methods to cure infections. To facilitate future research on these...
AbstractWe examined the potential of a common herbivore to indirectly influence other diverse community members by providing habitat. Larvae of the leafroller Anacampsis niveopulvella commonly construct shelters by rolling leaves of cottonwood trees. These leaf rolls are later colonized by other arthropods. We first documented 4 times greater species richness and 7 times greater abundance on cottonwood...
Altica carduorumandAltica cirsicolaare two species of leaf-feeding beetle (Coleoptera: Chrysomelidae) which appear to be morphologically indistinguishable and reportedly hybridize in the laboratory. A European population ofA. carduorumwas previously screened for host-plant specificity and released in North America for the control of Canada thistle,Cirsium arvense.A population ofA. cirsicolafrom China...
