Technical Abstract:
Growers in some regions of North America have rapidly adopted Bacillus thuringiensis (Bt) transgenic maize for controlling lepidopteran pests. Dramatic control of European corn borer, Ostrinia nubilalis, on these plants has many scientists concerned about high selection pressure to toxins in these plants and subsequent adaptation.In cotton-growing regions there are concerns about corn earworm, also called cotton bollworm, Helicoverpa zea, resistance to these plants. There are many complexities with Bt corn insect resistance management (IRM) that are being considered by scientists, regulators, and growers. Within a few years IRM may become even more complex as transgenic maize for coleopteran pests become available.This talk will emphasize current IRM issues including refuge management, educating growers, monitoring for resistance, remedial plans, and alternatives to current practices.
