摘要：
In this paper, a delayed predator-prey system with Beddington-DeAngelis functional response and harvesting terms is studied. By using Mawhin's continuation theorem, the sufficient conditions are established for the existence of at least four positive periodic solutions. Finally, an example is presented to illustrate the effectiveness of the results.
