| Abstract: | By using a continuation theorem based on coincidence degree theory,some sufficient conditions are obtained for the existence of positive periodic solution for a class of a delay predator-prey system with monotonic functional response and impulsive effect. Finally,three examples are given to illustrate the effectiveness of our results. |
