摘要
建立了一类被捕食者具有幼虫阶段的率依赖捕食-被捕食模型,通过对其平衡点稳定性的研究,得到其平衡点稳定的条件,为以虫治虫策略提供理论参考.并通过与无捕食模型稳态解进行比较,论证了"以虫治虫"策略的合理性.
A ratio-dependent predator-prey model on controlling Anoplophora chinensis by using Sclerodermus is established. By investigating the stability of the equilibria, the conditions on which the equilibira are stable are obtained. The results maybe provide some theoretical references for controlling Anoplophora chinensis. By comparing with the steady state solution of the model without prey, the rationality of the control method is discussed.
