有害生物综合防治体系中,人们主要通过生境控制或者使用选择性杀虫剂来保护天敌,从而增加天敌的数量,控制害虫。杀虫剂的选择性可以由生态的或者生理的方法实现,生态的方法主要是指在使用杀虫剂地区减少天敌接触药剂,生理的方法主要是指使用那些对害虫有效而对天敌相对安全的杀虫剂。不论生态的还是生理的方法,他们的最终目的都是要使生物防治更加有效。使用选择性杀虫剂
In integrated pest management system, people control the natural enemies mainly through habitat control or selective insecticides, so as to increase the number of natural enemies and control pests. The insecticide selectivity can be achieved ecologically or physiologically. The ecological approach mainly refers to reducing the exposure of natural enemies to pesticides in areas where the insecticide is used. The physiological method mainly refers to the use of insecticides that are relatively safe to natural enemies Pesticide. Their ultimate goal, both ecologically and physiologically, is to make biological control more effective. Use selective insecticides
