摘　　要：A non-autonomous predator-prey delay system with Beddington-DeAngelis functional response and impulsive controls is established. A set of sufficient conditions which guarantee the prey and the predator to be permanent are obtained.A non-autonomous predator-prey delay system with Beddington-DeAngelis functional response and impulsive controls is established.
