Abstract

BACKGROUND: Tools with the potential to predict risks of insecticide resistance and aid the evaluation and design of resistance management tactics are of value to all sectors of the pest management community. Here we describe use of a versatile individual-basedmodel of resistance evolution to simulate howstrategies employing single and multiple insecticides influence resistance development in the pollen beetle, Meligethes aeneus. RESULTS: Under repeated exposure to a single insecticide, resistance evolved faster to a pyrethroid (lambda-cyhalothrin) than to a pyridine azomethane (pymetrozine), due to difference in initial efficacy. A mixture of these compounds delayed resistance compared to use of single products. The effectiveness of rotations depended on the sequence inwhich compoundswere applied in response to pest density thresholds. Effectiveness of a mixture strategy declined with reductions in grower compliance. At least 50\% compliance was needed to cause some delay in resistance development. CONCLUSION: No single strategymeets all requirements for managing resistance. It is important to evaluate factors that prevail under particular pest management scenarios. The model used here provides operators with a valuable means for evaluating and extending sound resistance management advice, aswell as understanding needs and opportunities offered by newcontrol techniques.
