A Mutual Interference Stage-Structured Predator-Prey Model with Time Delay and Impulsive Perturbations on Predators
捕食者具脉冲扰动与相互干扰的阶段结构时滞捕食-食饵模型

A mutual interference stage-structured predator-prey model is considered with time delay and impulsive perturbation on predators. Sufficient conditions are obtained, which guarantee the global attractivity of pest-extinction periodic solution and permanence of the system. It is shown that all solutions of the system are uniformly ultimately bounded. The obtained results can be helpful for the practical pest management.
