Abstract

Abstract:

A non-autonomous multiple species Lotka-Volterra cooperative system with delayed biocontrols was investigated. With the aid of comparability theorem, constructing Lyapunov function and continuation theorem, a set of easily verifiable sufficient conditions were obtained to guarantee the permanent and positive periodic solution to be global attractivity of the system.

Key words: cooperative system, biocontrol, permanent, positive periodic solution, global attractivity
