The western corn rootworm, Diabrotica virgifera virgifera LeConte (shown above) and the northern corn rootworm, Diabrotica barberi Smith and Lawrence, are both important pests of corn in the Midwest. We study various tools for integrated pest management of rootworm.
integrated pest management
My research interests are in the areas of plant-insect and tritrophic interactions, with s focus on insects that attack corn Zea mays L. General themes include applications of ecological and evolutionary principles to improve integrated pest management and insect resistance management. Most of my work addresses questions concerning adaptation by pests to genetically modified crops that produce insecticidal toxins derived from the bacterium Bacillus thuringiensis (Bt), and tritrophic interactions among insects, plants and entomopathogens.
