天敌是害虫生物防治的资源之一。摸清天敌与害虫、环境条件、耕作制度、人为措施的相互关系,着手保护利用,进而达到以益灭害的目的。我站从1976年开始对棉田蜘蛛类天敌进行系统调查。1979年以来,又对棉田内天敌群落,越冬场所、主要种类的消长规律进行了调查,并通过采集饲养,观察天敌的种类及寄生率,同时对保护利用自然天敌,对棉虫综防的措施、效果进行了考查。
Natural enemies are one of the resources for pest biological control. To find out the relationship between natural enemies and pests, environmental conditions, farming systems and man-made measures and proceed with the protection and utilization so as to achieve the goal of exterminating benefits. I started from 1976 on a systematic investigation of spiders in cotton fields. Since 1979, the laws of the growth and decline of predators, overwintering places and main species in cotton fields have been investigated. Through the collection and rearing, the species and parasitism of natural enemies were observed. At the same time, the measures to prevent and control natural enemies, , The effect has been examined.
