| Abstract: | In this paper,we consider a cooperative model,which has a discrete delay,stage structure and cannibalism.By using the continuation theorem of coincidence degree theory,a sufficient condition is obtained for the existence of a positive periodic solution of this system. |

| Keywords: | staged structure coincidence degree delay cannibalism periodic solution |
