摘　　要：研究了具有反馈控制和时滞周期单种群Kolmogorov系统的周期解问题.应用迭合度理论,得到了判别系统正周期解存在的充分条件.In this paper, we consider a periodic single-species Kolmogorov type system with delays and feedback controls. Applying the continuous theorem of coincidence degree, a criterion on the existence of the positive periodic solution to the system is obtained.
