摘　　要：对广东省农业科学院茶叶研究所英德实验茶场进行调查,共有螨类10科,12属,17种。其中捕食性螨类6科,13种,捕食螨优势种为江原钝绥螨Amblyseius eharai。植食性螨类4科,4种,植食性螨类主要为卵形短须螨Brevipalpus obovatus。茶园释放胡瓜钝绥螨Amblyseius cucumeris释放后10～50d,对卵形短须螨的防治效果达23.30%～81.31%,可有效控制卵形短须螨的为害。并建议在应用中,每株茶树释放一袋胡瓜钝绥螨。There are 10 families, 12 genera, 17 species of mite in the Yingde Experimental Tea Plantation, Tea Research Institute, Guangdong Academy of Agriculture Science. 6 families, 13 species belong to predatory mites, and 4 families,4 species belong to the phytophagy ones.Amblyseius eharai dominates the predatory mites according to the species we collected, and Brevipalpus obovatus dominates the phytophagy ones. The effectiveness of releases of the predatory mite, Amblyseius cucumeris, for control of B. obovatus was evaluated. 10～50 days after the releasing of A. cucumeris, the control effect of B. obovatus ranged from 23.30% to 81.31%. As a result, the phytophagy mite, B. obovatus, was controlled sustainablely by A. cucumeris. It was suggested that releasing of one sachet of A. cucumeris by hanging the sachet in the tea canopy is enough to control the phytophagy mite B. obovatus.
