rootworm

David Ingber

M.S. student

My research interests lie in the examination of plant-insect interactions. My current research focus is examining the resistance of the western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte, to transgenic corn plants producing the Bt toxin Cry3Bb1. I am determining the genetic dominance and fitness costs of Bt resistance in several laboratory strains of WCR with field-derived alleles.

Assistant Professor

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.
