摘要：

Using Mawhin's continuation theorem of coincidence degree theory, we establish the existence of 2(n+m) positive periodic solutions for a non-autonomous Lotka-Volterra network-like predator-prey system with harvesting terms. Here n and m denote the number of prey and predator species respectively. An example is given to illustrate our results.
