A stage-structured Holling mass defence predator–prey model with impulsive perturbations on predators

摘要

In this work, we consider a stage-structured Holling mass defence predator–prey model with time delay and impulsive transmitting on predators. Sufficient conditions which guarantee the global attractivity of pest-extinction periodic solution and permanence of the system are obtained. We also prove that all solutions of the system are uniformly ultimately bounded. Our results provide reliable tactic basis for the practical pest management.
