Abstract

In this paper, a novel West Nile Virus model looking upon the infected birds as monitoring threshold, for the mosquitoes and birds with impulsive state feedback control is considered. We obtain sufficient conditions of the global asymptotical stability of the system without impulsive state feedback control via comprehensively qualitative analysis. By using the Poincar\'e map, we obtain that the system with impulsive state feedback control has a positive periodic solution of order-1 or order-2 which is asymptotical stability due to the analogue of Poincar\'e criterion, theory of differential inequalities, differential equation geometry and so on. What's more, sufficient conditions for existence and stability of the order one periodic solution are given by the existence and uniqueness of the limit. Our results show that the control measure is effective and feasible by means of numerical simulations.
