中文摘要：
讨论了具有非线性传染率与脉冲控制的害虫管理S-I传染病模型，此模型考虑的是脉冲投放病虫和喷洒农药．不但得到了系统的所有解的一致完全有界，而且得到了害虫灭绝的边界周期解的全局渐进稳定和系统的一致持久的条件．为实际的害虫管理提供了可靠的理论依据．
英文摘要：
A pest management S-I model with impulsive releases of infective pests and spraying pesticides is proposed and investigated.it was proved that all solutions of the model are uniformly ultimately bounded.The sufficient conditions of globally asymptotic stability periodic solution of pest-extinction and permanence of the model were also obtained.The approach of combining impulsive releasing infective pests with impulsive spraying pesticides provides reliable tactical basis for the practical pest management.
