| Abstract: | In this paper, we consider the periodic predator - prey system with time delays and impulsive effects to prey. By using the method of coincidence degree, some sufficient conditions are obtained for the existence of at least one strictly positive periodic solution. |

| Keywords: | impulsive periodic solution delay predator-prey system coincidence degree |
