Research Interests:

Population and community ecology of insects; biology of parasitoids; parasitoid-host interactions; predator-prey interactions; plant-insect interactions; agroecosystem ecology; landscape ecology; effects of habitat fragmentation on insect populations.

Research in my laboratory is focused on insect population and community ecology. We are examining the effects of vegetational diversity in annual agroecosystems on insect herbivores and their natural enemies, particularly predaceous insects and parasitoids. The purpose of this research is to discover ways to design agroecosystems to achieve the greatest biological control of insect pests. We are also interested in the influences of noncrop habitats adjacent to annual agroecosystems on herbivore and natural enemy populations associated with those agroecosystems, as well as habitat fragmentation effects on arthropods.
