Abstract: This paper studies a mutual interference stage structured predator-prey system with varying delay. By using the comparison principle of differential inequations and an iteration scheme, a set of sufficient conditions are obtained for the global attractivity of a unique positive equilibrium of the system. An example with its numerical simulations shows the feasibility of the main results.

Key words: stage structure, mutual interference, global attractivity, predator-prey, varying delay
