This paper introduces the systematic model for the pulse population, which is applied to the reseach of predator release and plantation of trees at fixed moment, based on the biological control strategy of injurious insects. By means of Floquer theory and comparison principle, this paper studies the existence of the periodic solution to injurious insect extinction as well as the overall asymptotic stability. Meanwhile, the condition of the system constant existence is given.
