摘要
本文讨论了一类杀虫剂具有残留效应的害虫治理模型的动力学性质.假设释放天敌周期内等周期喷洒杀虫剂,利用污染模型模拟喷洒杀虫剂过程建立害虫治理模型,给出了一嵌套系统,并利用原系统的极限系统给出害虫灭绝周期解全局吸引的充分条件.
In this paper,we study on the dynamic property of an pest control model with Dose response to pesticides.We suppose pesticides are sprayed several times in a periodic of natural enemy releases,by pollution model simulating the spraying process,establish a nested system and by the limit system of original system obtain the sufficient condition of the global attractiveness on the trivial periodic pest-eradication solution.
