Summary: A delayed ratio-dependent predator-prey discrete-time model with non-monotone functional response is investigated. By using the continuation theorem of Mawhins coincidence degree theory, some new sufficient conditions are obtained for the existence of multiple positive periodic solutions of the discrete model. An example is given to illustrate the feasibility of the obtained result.
