| Abstract: | In this paper,the author study the existence of periodic solutions for a delayed stage-structure predator-prey system with harvesting rate,by developing some technique of analysis and using continuation theorem baser on Mawhin's coincidence degree,a set of easily verifiable sufficient conditions are derived which this systems has at least two positive periodic solutions. |
| Keywords: | harvesting rate stage-structure predator-prey system positive periodic solutions coincidence degree |
