I am characterizing the genetics of western corn rootworm strains that have been selected for survival on maize expressing the Cry34/35Ab1 insecticidal proteins. I also work full time for DuPont-Pioneer.
I conduct field trials testing both commercial and pre-commercial products for management of insect pests of corn. Much of my work focuses on western and northern corn rootworm, but I also have studied products targeting corn earworm, European corn borer, fall armyworm, seedcorn maggot and wireworm. I conduct trials on Iowa State University Research farms and in farmers' fields.
