Develop colonies with resistance to Cry34/35Ab1 and test the effectiveness of two refuge types to delay resistance. Test the dominance and fitness costs of resistance to Bt corn.
Western corn rootworm colonies will be selected for resistance to Cry34/35Ab1-expressing transgenic maize and resistance levels will be compared to control colonies and colonies designed to simulate a refuge. In addition, dominance of resistance will be tested by crossing resistant and susceptible colonies and evaluating progeny and fitness costs associated with resistance will also be evaluated.
