Abstract: We first establish the periodic difference model with feedback controls and delay, then with the help of a continuation theorem based on Gains and Mawhin coincidence degree, easily verifiable criteria are obtained for the existence of positive periodic solutions of a periodic difference model with periodic delays and feedback controls.
