文摘In this paper, a predator -prey model with stage structure and double time delays in pollution environment is modeled. By using comparison theorem of impulsive differential equation, dynamics behaviors of the system is analysised. We prove that the pest-extinction solution of the system is the globally attractive for R 1 <1.
