Abstract
In this paper, a non-autonomous predator-prey system with ratio-dependence type functional response and stage structure for predator and time delay in patch circumstances is investigated. By using Gaines and Mawhin´s continuation theorem of coincidence degree theory, a set of easily verifiable sufficient conditions to guarantee the existence of positive periodic solutions of the system are obtained. Some new results are obtained.
