Tooker Lab

Plant-Insect Interactions in Agroecosystems -- We study relationships among plants, insect herbivores, and natural enemies to understand factors that regulate populations of herbivorous insects. We are interested in both plant- and natural-enemy-mediated factors and how they influence insect behavior, community composition, and herbivore mortality. Our long-term goal is to exploit the ecology/biology of our study organisms to provide strategies and tactics for more sustainable insect pest management.
