Abstract
In this paper, we consider a three-species ratio-dependent predator-prey model governed by difference equations with periodic coefficients and discrete time, in which two cooperative preys are preyed by one predator. By using the method of coincidence degree, we discuss the existence of positive periodic solutions of this system; a set of easily verifiable sufficient conditions is obtained.
