摘　　要：为摸清海南橡胶园捕食螨种类及其优势种,本研究于2015—2016年,采用五点取样法进行捕食螨种类的调查采集,采用优势度和频度等指标进行优势种评价。结果表明:海南橡胶园的捕食螨有植绥螨科、囊螨科和吸螨科等3个科,其中,植绥螨科的数量最多,占样本总数的85.05%,其次是囊螨科,占样本总数的14.71%,吸螨科捕食螨的数量最少,占样本总数的0.24%。对植绥螨科的4属13种捕食螨进行综合评价表明邻近钱绥螨(Chanteius contiguus)、普通真绥螨(Euseius vulgaris)、海南钝绥螨(Amblyseius hainanensis)是海南南部橡胶园的优势种捕食螨,而卵圆真绥螨(Euseius ovalis)是海南北部橡胶园的优势种捕食螨,南部和北部橡胶园的优势种捕食螨种类及数量存在较大差异。本研究结果可为进一步利用捕食螨防治六点始叶螨(Eotetranychus sexmaculatus)、东方真叶螨(Eutetranychus orientalis)等橡胶叶螨的生物防治提供理论依据。In order to find out the species of predatory mites and the dominant species of predatory mites in rubber trees in Hainan.We investigated the species by a five-point sampling method from 2015 to 2016,and evaluated the dominant species through dominance and frequency.The results showed that there were three families of predatory mites which were Phytoseiidae,Ascidae and Bdellidae,and Phytoseiidae as the most abundant species,constituting 85.05%of the total samples,followed by Ascidae,14.71%,and Bdellidae the least abundant species,0.24%.A comprehensive analysis of 13 species of predatory mites belonging to 4 genera in the family of Phytoseiidae was conducted through dominance and frequency.The results showed that the dominant species of the predatory mites in rubber trees in southern Hainan included Chanteius contiguus,Euseius vulgaris and Amblyseius hainanensis,with C.contiguus as the dominant species in rubber trees in southern Hainan,while Euseius ovalis as the dominant species in rubber trees in northern Hainan.The species and quantity of the dominant species in rubber trees in southern and northern Hainan differed greatly.This study would provide a theoretical basis for the further utilization of predatory mites in the biological control of Eotetranychus sexmaculatus and Eutetranychus orientalis in rubber trees.
