| Abstract: | Based on integrated pest management strategy,a stage-structured and delayed predator-prey system with impulsive effect is proposed and analyzed.The positive solutions are ultimately bounded.Sufficient conditions are derived for the global attractivity of the pest-eradication periodic solution and the permanence of the system. |

| Keywords: | stage-structure delay impulses permanence pest extinction |
