摘要

研究了食饵受病毒感染且捕食者具有Beddington-DeAngelis功能性反应的生态流行病模型,
此模型考虑的是脉冲释放病毒颗粒和自然天敌. 利用Floquet乘子理论、小振幅扰动技巧和比较定理证明了害虫根除周期解的全局渐近稳定性以及系统持续生存的充分条件.结论为现实的害虫管理提供了有效的策略依据.

Abstract

In this paper, a pest management viral infection model with impulsive releases of viral particles and natural enemies is proposed and investigated. The sufficient
conditions of globally asymptotic stability of pest-eradication periodic solution and the permanence of the model are obtained by using Floquet's theorem, small-amplitude perturbation skills and comparison theorem. The results provide effective tactic basis for the practical pest management.
