A Delayed Stage-structured Predator-Prey Model with Impulsive Stocking on Prey

In this work, we investigate a delayed stage-structured Holling II predator-prey model with impulsive stocking on prey. Sufficient conditions of the global attractivity of predator -extinction periodic solution of the system are obtained. These results show that the behavior of impulsive stocking on prey plays an important role for the global attractivity of the system. Our results provide reliable tactical basis for the biological resource management.
