摘要
2010-2012年通过对西双版纳州橡胶林的害螨及其天敌进行2年多的调查。结果表明：西双版纳州橡胶树害螨主要有2种，分别为六点始叶螨（EotetranychussexmaculatusRiley）和海南小爪螨（Oligonychus hainanensisMa，YuanetLin）；并详细记述了2种害螨的形态特征、为害特点及发生数量：初步调查到六点始叶螨的天敌19种，隶属2个纲、7个目、10个科，采用优势度指数评价法得m优势种群为草蛉、食螨瓢虫和捕食螨．三者都具有较好的应用前景；初步摸清六点始叶螨主要天敌发生消长及其自然控制作用．
Main mites and natural enemies of the dominant mite on rubber trees in Xishuangbanna were surveyed from 2010 to 2012. The results indicated that there were two species of main mites which were Eotetranychus sexmaculatus Riley and Oligonychus hainanensis Ma, Yuan et Lin. The morphological characteristics, damage characteristics and quantities of the two species of harmful mites were recorded. There were about 19 species of natural enemies on E. sexmaculatus Riley, which could be divided into 10 families, 7 orders and 2 classes. The most abundant species were green lacewing, ladybug and predatory mite which were evaluated with dominance index. They all may be used to control E. sexmaculatus Riley. Population dynamics of master natural enemies and natural control effects on E. sexmaculatus Riley were primarily found out.
