内容介绍：In this paper, we mainly investigate a delayed predator–prey model with stage structure for prey and Ivlev-type functional response. The stability of equilibria and existence of Hopf bifurcation are studied by discussing the different cases of time delays for the model. Meanwhile, we derive explicit formulae to determine the properties of Hopf bifurcation such as the direction of Hopf bifurcation and the stability of periodic solutions. Numerical simulations of all theoretical analyses are given for verifying our theoretical results. These results may be helpful to further understand the role of the critical values of time delays in stabilizing the predator–prey model.
