Kevin Douglas Floate is a research
scientist with broad interests in insect community ecology.
He has examined the role of ground beetles (Carabidae) as natural
enemies of pests affecting wheat, and the response of gall-forming
arthropods to the hybridization of their cottonwood (Populus)
host species. He currently studies the biology and ecology of
parasitic wasps for use as biocontrol agents against flies affecting
livestock. He has expanded this research to include studies
of Wolbachia bacteria, which have profound effects
on the reproduction of their arthropod hosts and which affect
an estimated 20-80 percent of arthropod species.
Kevin's specific interest in Scarabaeidae derives from their
membership in the community of insects associated with livestock
dung, and how this community is affected by parasiticides applied
to cattle. This information is being used to develop guidelines
to minimize the adverse effects of pesticide use on non-target
species.
