| Abstract: | In this paper,a non-autonomous dispersal-delay predator-prey system with Beddington-DeAngelis functional response is studied.By using the coincidence degree theory,a set of easily verifiable sufficient conditions are derived for the existence of positive periodic solutions of the proposed model. |
