摘要 讨论了一类具有Leslie形式且捕食带有寄生虫感染的捕食系统,得到了该系统持续生存在的条件,给出了系统平衡点局部渐近稳定的条件,并分析了相应的时滞捕食系统正平衡点局部Hopf分支存在的条件. We mainly study the dynamical behaviors of a predator-prey system with Leslic type and predators infected by microparasitc.We prove the persistent existence of the system and conclude the sufficent condisions of local asymptotically stability about equilibriums.It is found that there is stability switch for time delay,and Hopf bifurcation occurs when time delay crosses through a critical value.
