In this paper, a nonautonomous predator-prey dispersion delay models with functional response is studied. By using the continuation theorem of coincidence degree theory, the existence of a positive periodic solution for above models is established.
Keywords: positive periodic solution, predator-prey dispersion delay model, functional response, the continuation theorem of coincidence degree theory
