摘　　要：茶园适期释放胡瓜钝绥螨可以有效降低茶园害螨的危害,在茶园害螨危害盛期前按照每亩6~7万头总量释放捕食螨,放螨20 d后,对茶园跗线螨的防治效果为76.13%。在茶园茶橙瘿螨发生期,释放捕食螨10 d后,防治效果52.50%,释放捕食螨20 d后,防治效果81.76%。Efficacy of releasing predatory Amblyseius cucumeris Oudemans in tea plantations to mitigate damages brought about by phytophagous mites was evaluated. Predatory A. cucumeris were released at a rate of 60000 ~ 70000 mites/667 m2 before peak infestation period at a tea plantation. Twenty days after the release, the control on Polyphagotarsonemus latus reached 76.13%. Comparatively, the same biological control measure produced an efficacy of 52.50% in 10 d and 81.76% in 20 d on Acaphylla theae Watt.
