昆虫对杀虫剂发生抗性是化学防治中一个重要的问题,近年来许多人在研究防止抗性发生以及延缓抗性发展的方法与策略。许多方法及策略曾被试验应用过,多数并不十分成功,其原因或是没有实际应用价值(例如增效剂或解毒酶的抑制剂,像“抗DDT”这一剂型就没有能应用);或是根本上这个方法或策略是行不通的,不能起作用,因为它的理论基础是错误的(例如,混用几种杀虫剂,尽管它们的作用机制并不相同)。 Insect resistance to insecticides is an important chemical control problem. In recent years, many people are studying methods and strategies to prevent the occurrence of resistance and delay the development of resistance. Many methods and strategies have been tested and most have not been very successful due to their lack of practical utility (eg, inhibitors of synergistic or detoxifying enzymes such as the “anti-DDT” formulation). Or, fundamentally, this method or strategy will not work and will not work because its rationale is wrong (for example, mixing several pesticides, even though their mechanism of action is not the same).
