| Abstract: | In this paper,by using the comparing theorem and V-function method,we consider a nonautonomous tow-preys one-perdator system with stage stucture and time-delay.We get the sufficient conditions for the uniform persistence and the solutions global sttractivity of this system.And we obtain the existence and uniqueness of a positive periodic solution of this system. |

| Keywords: | periodic solution global attractivity uniform persistence |
