摘要
According to biological and chemical control strategy for pest, we investigate the dynamic behavior of a Lotka-Volterra predator-prey state-dependent impulsive system by releasing natural enemies and spraying pesticide at different thresholds. By using Poincare map and the properties of the Lambert W function, we prove that the sufficient conditions for the existence and stability of semi-trivial solution and positive periodic Solution. Numerical Simulations are carried Out to illustrate the feasibility Of Our main results. (c) 2008 Elsevier B.V. All rights reserved.
