| 摘 要： | 研究了与害虫管理相关的一类捕食者(益虫)具有脉冲扰动,食饵(害虫)具有化学控制的阶段结构时滞捕食-食饵模型,根据生物资源管理的实际,改进了原有捕食者-食饵模型,得到了害虫灭绝周期解全局吸引和系统持久的充分条件。得出的结论为现实的害虫治理提供了可靠的策略依据。

| Abstract: | A stage structured delayed pest management predator prey model with impulsive transmitting on predators (beneficial insect) and chemical control on prey (pests) concern was considered. According to the living resources managements reality, improved the predator prey model, sufficient condition of the global attractivity of pest exterminate periodic solution and permanence of the system were obtained. The results provide reliable tactical basis for the practical pest management. |
