In this paper, the existence of 2n positive periodic solutions for n species nonautonomous LotkaVolterra cooperative systems with harvesting terms is established by using Mawhins continuation theorem of coincidence degree theory and matrix inequality. An example is given to illustrate the effectiveness of our results.
