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。
Investigation of Yingde Experiment Tea Plantation of Tea Research Institute of Guangdong Academy of Agricultural Sciences included 10 families, 12 genera and 17 species of mites. Among them, 6 families and 13 species of predatory mites and Amblyseius eharai were the predominant species of predatory mites. There are 4 families and 4 species of phytophagous mites, and Brevipalpus obovatus mainly belongs to phytophagous mites. The control effect of Amblyseius cucumeris released from tea plantation Amblyseius cucumeris was 23.30% ~ 81.31% after 10 ~ 50d release, which could effectively control the damage of ovoid short-fiber mites. It is also suggested that in the application, a bag of cucumber Amblyseius spp. Be released per plant.
