| 摘 要： | 研究了一类具有阶段结构的害虫-天敌系统。当使用杀虫剂消灭害虫时,研究脉冲形式的控制,得到了无天敌时系统存在稳定的周期解。然后利用分支理论,讨论害虫-天敌模型的非平凡周期解,周期解由稳定变成不稳定的。

| Abstract: | This paper studied a class of pest-natural enemy model with stage structure.The impulsive control strategies was investigated when pesticides were used to kill pest.The stable periodic solution was obtained for the natural enemy-free system.Furthermore,the existence of nontrivial periodic solution of pest-natural enemy model was considered by using bifurcation theory.The stable nontrivial periodic solution becomes unstable. |
