Stability and Hopf Bifurcation of a Predator-Prey Model with Dual Time-Delay
A dual time-delay predator-prey model with B-D functional response and different refuge behav-iors is established,and the stability and Hopf bifurcation of the positive equilibrium of the model with different time-delays are analyzed.The research shows that when the time-delay is equal to the corre-sponding critical value,Hopf bifurcation occurs at the positive equilibrium of the model,and the stability of the positive equilibrium changes.
