We modified an existing model for European corn borer, Ostrinia nubilalis (Hübner), population dynamics and genetics to evaluate resistance management when there was oviposition deterrence to the transgenic fields. Oviposition deterrence was clearly effective in extending the time to resistance to transgenic corn (R allele) in the European corn borer, particularly when 80% or more of the eggs were deterred from being oviposited on the transgenic plants. With 90% of eggs deterred, the time required to reach 50% R-allele frequency increased 3.7- to 5.5-fold compared to the no-deterrence scenario.
