利用天敌防治害虫是害虫综合防治的一个重要内容,尤其对害螨的防治,效果更为突出。但是,在害虫综合防治中,不能排除化学农药的作用。而这些化学农药在消灭害虫的同时,也消灭了大量的天敌。人们为了协调生物防治和化学防治的矛盾,达到既消灭害虫,又保护天敌,把防治对象控制在经济允许为害水平以下的目的,便把希望寄托在抗药性天敌的开发和利用上。近年来进展很快,研究的重点是抗药性捕食螨的应用,这项研究在许多国家和地区已获得成功,并有专著予以综述。
The use of natural enemies to control pests is an important aspect of comprehensive pest control, especially for the prevention and treatment of harmful mites, the effect is more prominent. However, the role of chemical pesticides can not be ruled out in the integrated pest management. While these chemical pesticides in the elimination of pests, but also eliminated a large number of natural enemies. In order to coordinate the contradictions between biological control and chemical control, people can not only eliminate pests but also protect their natural enemies and control their targets below the level permitted by the economy, placing their hopes on the development and utilization of resistant natural enemies. Progress has been made rapidly in recent years. The research focus has been on the use of drug-resistant predatory mites. This study has been successful in many countries and regions and has been reviewed by monographs.
