荔枝(Litchi chinensis)害螨仅记述过荔枝毛瘿螨(Eriophyes litchii)和比哈小爪螨(Oligonychus biharensis)两种。最近笔者在漳州、龙海九湖和南安县农科所等地荔枝园中采集到另一种叶螨,初步鉴定为海南小爪螨(Oligonychus hainan-ensis)。 一、为害情况 目前仅发现该虫幼螨、若螨和成螨为害荔枝叶片,受害叶片正面呈现许多灰白色小斑点,严重发生时常导致叶片脱落。1986年9月间第一次秋梢曾因被害而引起严重落叶。

Recently, the author collected a variety of spider mites in the litchi garden of Zhangzhou, Longhai Jihu and Nanan Agricultural Institute, and was initially identified as Oligonychus hainan-ensis. First, the damage situation Currently only found the larvae larvae, if the mites and adult mites damage lychee leaves, the victim leaves showed many small white spots on the positive, often lead to serious leaves off. In September 1986, the first autumn shoot was severely defoliated due to the victimization.
