Dynamics behaviors of a delayed stage-structured predator–prey model with impulsive effect

In this paper, we analyzed a delayed stage-structured predator–prey model with impulsive stocking on prey and continuous harvesting on predator. Sufficient conditions for the global attractivity of ‘predator-eradication’ periodic solution and permanence of the system are obtained. The results show that the behavior of impulsive stocking on prey plays an important role for the permanence of the system.
