摘要
基于害虫综合治理策略,建立了具有Monod-Haldance功能性反应的不同固定时刻分别投放染病害虫、天敌和喷洒化学农药的传染病模型.通过脉冲微分方程的小振动技巧、Floquet定理和比较定理,得到传染病模型中易感害虫灭绝周期解渐近稳定(局部和全局)的条件.并且利用Matlab软件通过调节相应的参数进行验证,得到模型的正确性.同时接下来可以继续深入研究的方向和课题.此模型的适用性很强,在农林业中可以用来指导实践.
In the paper,we establish the pest-epidemic model with the Monod-Haldance functional response topresent the process of periodic spraying pesticide and releasing natural enemies and infected insect at different fixed moments.The sufficient conditions for the local stability and the globally stability of prey eradication periodic solution are obtained by using the Comparison theorem and Floquet theorem.Finally,we use numerical simulations to verify the feasibility of the obtained results by Matlab.At the same time,the problems that can be further studied in this paper are given.This model has strong applicability,which can be used to guide practices.
