| Abstract: | The predator-prey system with periodic impulsive intervention at different time points, is investigated, With releases natural enemies either more or less frequent than harvests, a stability threshold condition for pest eradication periodic solution is provided, and the periodic of releases effects was studied on integrated pest management （IPM）. The results provide tactical basis for the practical pest management. |

| Keywords: | biological control periodic impulsive periodic solution predator-prey model |
