摘要
In this paper,we have considered a prey-predator system with selective harvesting of predator species.The stability of the three equilibria and the existence of Hopf bifurcation are investiateed.It is found that tree are Hopf bifurcations occur when the delay τ passes through a sequence of critical values.
