Abstract: The European corn borer (Ostrinia nubilalis; ECB) is a primary pest that is now largely managed with transgenic Bt corn. We investigated the gene flow and genetic structure within and between ECB populations in the northeastern US, where the varied topography and the sympatric populations of partly reproductively isolated pheromone races (E and Z) may restrict gene flow and allow resistance to evolve more quickly. The higher than expected hybridization between pheromone races found by a novel screen method may also affect the rate of resistance development and spread.
