摘要
研究一类害虫管理SI传染病模型,考虑脉冲投放病虫和人工捕杀相结合,得到系统的灭绝周期解,给出此周期解的全局吸引性,并获得了系统一致持续生存的条件.给出了害虫管理综合防治策略.
In this work, we consider an SI epidemic disease model for pest management, and concern about pulse releasing infective pest and killing pest by hands. The 'susceptible pest- exterminate' periodic solution is obtained, and the global attractivity of the 'susceptible pest- exterminate' periodic solution is given. Furthermore, the sufficient condition for'permanence of the system is obtained. The integrated control strategies for pest management are given.
