Abstract
The evolution of insecticide resistance amongst insect pests is a world-wide problem. Of particular concern is the recent use of transgenic crops expressing Bt toxins. Current resistance management strategies rely on the dispersal of susceptible insects from areas free of insecticide use. There is an urgent need for the effectiveness of this strategy to be tested, with few previous studies using models based on empirical systems. This study aims to combine empirically measured gene flow data with spatial genetic models. New mathematical techniques will be developed for studying genetic variability and gene flow within metapopulations. Genetic markers for Bt resistance will be used to test predictions of the model in the field.
