Technical Abstract: Managing resistance of corn insect to Bt corn is necessary. Bt corn is valuable and all stakeholders want to preserve its efficacy. Currently, the high-dose/refuge strategy is the resistance management strategy of choice. There are, however, potential problems with this strategy. Research is underway to try to better define these problems and to offer solutions. A resistance management forum, like the NC-205 Resistance Management meeting, greatly facilitates cooperation among all stakeholders and expedites solutions to possible problems. Genetic factors identified as high research priorities for managing corn insect resistance include gene frequency, number of resistance genes, functional dominance, and fitness of resistant insects. Developing efficient techniques to monitor for resistance is a high priority. Biological factors identified as high research priorities include larval movement, adult mating, migration, and refuge.
