Research and/or project statements

Damage from pest insects can reduce yield or even devastate crop yields. Control methods such as insecticide can kill pest insects, but also harm the many beneficial predacious insects that provide free and natural pest control. My research program contributes to sustainable crop production through reducing losses to pest damage and lowering input (pesticide) costs. Integrated pest management techniques are achieved through studying basic pest biology, identifying threshold levels of pest abundance that warrant insecticide use, understanding how and when beneficial insects contribute to pest control, understanding how agronomy affects insect communities, and working with plant breeders to develop insect resistant crop varieties.
