Abstract

This paper extends a three-species competitive-cooperative model appeared in the literature to a system not only included discrete delays, but also included distributed delays. The instability of the solutions is concerned. Computer simulation is provided to verify the criteria.

Keywords: Competitive-cooperative model, delay, instability, positive periodic solution
