农药抗性的产生对害虫防治效果有重要影响。农药抗性发展对害虫综合管理（IPM）策略和害虫控制结果的影响的定量描述具有挑战性。为了解决这一问题，提出并分析了具有农药抗性发展和IPM策略的离散寄主-寄生蜂模型。提出并分析了揭示害虫抗性发展与天敌释放率之间关系的消灭害虫阈值条件，并在此阈值条件下得到了最优天敌释放率。此外，为了减少农药对天敌的不良影响，将模型扩展到考虑不同时间的农药喷洒和天敌释放。讨论了动态复杂性和不同阻力发展方程对主要结果的影响。
ABSTRACT The development of pesticide resistance significantly affects the outcomes of pest control. A quantitative depiction of the effects of pesticide resistance development on integrated pest management (IPM) strategies and pest control outcomes is challenging. To address this problem, a discrete host-parasitoid model with pesticide resistance development and IPM strategies is proposed and analyzed. The threshold condition of pest eradication which reveals the relationship between the development of pest resistance and the rate of natural enemy releases is provided and analyzed, and the optimal rate for releasing natural enemies was obtained based on this threshold condition. Furthermore, in order to reduce adverse effects of the pesticide on natural enemies, the model has been extended to consider the spraying of pesticide and releases of natural enemies at different times. The effects of the dynamic complexity and different resistance development equations on the main results are also discussed.
