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。

关键词: 阶段结构, 脉冲, 时滞, 害虫管理, 全局吸引, 一致持久

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 managements 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.

Key words: stagestructured, impulsive, delayed, pestextinction, global attractivity, permanence
