摘要：

By using a continuation theorem based on Gaines and Mawhin's coincidence degree, we study the global existence of positive periodic solutions of a delayed predator-prey system with ratio-dependent functional response and stage structure for predator. A set of easily verifiable sufficient conditions are obtained, which improve some known results.
