The model of a kind of predator-parasite-pest system is built in t his paper in which the parasite population is controlled by predator in such a way that it preys upon the pest individuals parasitized. A disgusty of predator for preying upon the pest individuals parasited is introduced in the model to measure the intensity that the parasite population was controlled by the predator.The persistence and the stability are studied for this system mathematically. And the influence of the disgusty on the persistence of the system is also noticed in biology.
