We consider a delayed predator-prey system with Holling II functional re-sponse. Firstly, the paper considers the stability and local Hopf bifurcation for a delayed prey dator model using the basic theorem on zeros of general transcendental function, hich was established by Cook etc.. Secondly, special attention is paid to the global existence of periodic solutions bifurcating from Hopf bifurcations. By using a global Hopf bifurcation result due to Wu , we show that the local Hopf bifurcation implies the global Hopf bifurcation after the second critical value of delay. Finally, several numerical simulations supporting the theoretical analysis are given.
