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.

This summer has been full of insects, corn, soy, and so much dirt! I am Dan Wisniewski a rising sophomore majoring in Plant Science with a minor in Environmental Resource Management at Penn State.
Podcast: Collateral Neonic Impacts
July 11, 2017
Neonicotinoids (neonics) are a class of insecticides based on natural plant compounds that disrupt the insect nervous system. They are used because they have relatively low toxicity on non-insects. They are applied as seed coatings, so when a seed germinates the water-soluble insecticides are taken up and mobilized throughout the plant, providing protection against insects that feed on it. The strategy decreases the need for aerial spraying of broad-spectrum insecticides.
