| Abstract: | Persistence and stability of a nonautonomous two-species n-patches predator-prey dispersal system with time varying delay and multiple infinite delays and Holling type-II functional response were studied.By using of the comparison theorem and constructing suitable Lyapunov functional,sufficient conditions were obtained for guaranteeing the permanence of the system and the globally asymptotic stability of any positive solution. |

| Keywords: | time varying and infinite delays dispersion permanence globally asymptotic stability |
