Dr. Doudna studied the distribution of Bt-resistant western corn rootworm (WCR) (Diabrotica virgifera virgifera) throughout Iowa, and how the evolution and spread of resistance are impacted by field management and landscape characteristics. He sampled sites throughout Iowa and used GIS to evaluate landscape and management parameters associated with the presence of resistance.
Julie completed a Master of Agriculture in professional agriculture while working full time at BASF. Her research tested novel products for management of twospotted spider mites in greenhouses.
Dr. Hannon conducted postdoctoral research on fitness costs of resistance to Bt toxin Cry1Ac in pink bollworm, Pectinophora gossypiella, and how these fitness costs were affected by entomopathogenic nematodes.
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.
Dr. Deitloff's postdoctoral research tested how non-Bt refuges affected the evolution of resistance to Bt corn by western corn rootworm. She also conducted research on the potential for assortative mating among Bt-resistant and Bt-susceptible insects.
Robert completed an M.S. in entomology that tested whether soybean varieties with resistance to soybean aphid affected defoliating insect pests.
For her master's degree, Amanda tested whether the ecological important variables of host-plant resistance and entomopathogens could affect the magnitude and dominance of fitness costs associated with resistance to Cry3Bb1 in western corn rootworm.
During her time as a postdoctoral scientist at Iowa State University, Dr. Maxwell studied a diversity of topics, including fitness costs of Bt resistance in western corn rootworm and European corn borer, tritrophic interactions among soil-borne entomopathogens, corn and western corn rootworm, and the application of integrated refuges and Bt pyramids to manage the evolution of resistance.
Melissa completed a master's degree in entomology. She studied tritrophic interactions among western corn rootworm, soil-borne entomopathogens and Bt corn.
Dr. Jakka's research focused on Bt resistance monitoring, characterization of Bt resistance and cross-resistance patterns among Bt toxins for western corn rootworm (Diabrotica virgifera virgifera).
