Abstract:

In this paper, we study a stage-structured predator-prey model incorporating time delay with prey growth subject to a strong Allee effect. By analyzing the characteristic equation of the corresponding linearized system, we investigate the local asymptotic stability of the system according to the change of birth rate in prey. Using the delay as a bifurcation parameter, the model undergoes a Hopf bifurcation at the positive equilibrium when the delay crosses some critical values. On the other hand, we show that both predators and prey will go extinct if the birth rate is small or the Allee effect is large. © 2019, International Association of Engineers.
