| Abstract: | In this paper, a delayed predator-prey systems with Holling-II type functional response and Harvesting Terms has been investigated. With the generalized continuation theorem and differential inequality skills, the existence of four positive periodic solutions has been established for delayed predator-prey systems with Holling-II type functional response and Harvesting Terms. |
