柚子树上的捕食螨 Predatory mites on grapefruit leaves [图文 Text with pictures]

We found many predatory mites on almost every leaf of grapefruit trees in our campus, 15 individuals per leaf at most. There might be phytoseiid mites and Anystid mites. The predatory mites occured mostly near the main vein since the hairs can provide shelter and the eggs and adults of citrus red mite also distribute there.  

由于没有打药,校园22棵柚子树上捕食螨较多,几乎每片叶子都有,最多可发现15只。拍到了植绥螨科、大赤螨科等成螨及卵的照片,发现捕食螨多喜欢在主脉活动,上面多毛,提供了隐蔽所,另外一个原因是柑橘红蜘蛛的卵和成虫也多在主脉。

经蜱螨实验室QQ群的金平初步确定有植绥螨

Preliminary identification by Jin Ping @ Acari Lab QQ Group to confirm the present of Phytoseiidae.

If you can help to identify the mite species, please tell me, thanks. 如能帮助鉴定捕食螨种类,非常感谢!
