摘要
考虑到杀虫剂在进入害虫体内产生的滞后及残留效应等因素,本文引入杀虫剂剂量反应函数,建立了相应的单种群害虫治理模型,讨论了以害虫灭绝为控制目的的化学控制策略,得到了害虫灭绝临界条件及害虫灭绝或爆发的关键因素.
In this paper,concerning the delayed effects and residual effects after pesticides entering pests and other factors,a pollutant discharge model is suggested to simulate pesticide spraying,and we introduce successfully the dose-response function to the single species pest control model.We discuss the chemical control strategy to eradicate pests and obtain the critical condition of pest-eradication and the key parameter affecting pest outbreak or extinction.
