摘要
将害虫对杀虫剂的抗性发展及周期性轮换使用杀虫剂引入具有不同时刻脉冲作用的综合害虫治理模型,利用脉冲微分方程的基本理论和分析方法给出害虫根除周期解存在及全局吸引的充分条件.
An integrated pest control model with impulsive effects at different fixed time was proposed by introdu -cing resistant development and periodic using pesticides in rotation .The sufficient conditions of the existence and glob-al attractiveness of pest-eradication periodic solution were given by using the basic theory and analysis methods of im -pulsive differential equation .
