This paper is concerned with a non-autonomous stage-structured predator-prey model with harvesting terms. By means of the coincidence degree theory, we establish the existence of at least eight positive periodic solutions for the system under consideration. An example is given to illustrate the effe
## a b s t r a c t In this paper, by employing the continuation theorem of coincidence degree theory, we establish an easily verifiable criteria for the existence of at least four positive periodic solutions for a discrete time delayed predator-prey system with nonmonotonic functional response and
