摘要 研究了一个关于害虫防治的有脉冲效应以及年龄结构和时滞的捕食-被捕食模型,得到了害虫根除的周期解全局吸引以及系统持久的充分条件,同时证明了系统所有的解是一致最终有界的.这些结果能为害虫防治的实际操作提供一定的理论依据. We investigate a delayed stage-structured predator-prey model with mutual interference and impulsive perturbations on predator. Sufficient conditions of the global attractivity of prey-extinction periodic solution and the permanence of the system are obtained. We also prove that all solutions of the system are uniformly ultimately bounded. Our results provide reliable tactical basis for the practical pest management.
