Josh completed a Masters in Seed Technology and Business while working full time at DuPont Pioneer. His project was a literature review covering cases of field-evolved resistance to Bt crops (corn and cotton).
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.
