By means of the coincidence degree theory and its related continuation theorem, the existence of periodic solutions of nonautonomous predator-prey model controlled by impulse are investigated in this paper. The results extend earlier ones where impulses are absent. Further, using numerical simulation method the influences of the impulsive perturbations on the inherent oscillation are investigated. The numerical simulation shows that our models can occur in many forms of complexities including periodic oscillation and Gui strange attractor.
