For a class of Holling type II food chain systems with biological and chemical controls, we give conditions of the local stability of prey-free periodic solutions and of the permanence of the system. Further, we show the system is uniformly bounded.
Keywords: Holling type II food chain system, biological and chemical controls, impulsive differential equation, Floquet theory
