| Abstract: | A non-autonomous food-chain system with infinite delay and feedback control is studied.By applying the comparative theorem and constructing a suitable Lyapunov functional,some sufficient conditions are obtained for guaranteeing that the system is permanent and global attractivity. |

| Keywords: | infinite delay feedback control food-chain permanent global attractivity |
