摘要：

In this paper, by using the continuation theorem of coincidence degree theory, we obtain the existence condition of at least four periodic solutions for a delayed ratio-dependent predator-prey system. An example is represented to illustrate the feasibility of our main result. (C) 2014 Elsevier Inc. All rights reserved.
