我场地处东南沿海,常年温湿多雨,山上松、竹、杂林茂密,利于各种害虫繁殖,特别是危害茶树的蚧类、螨类近几年来危害猖獗,山上下互相传染,如龟腊蚧、红腊蚧、茶梨蚧等在山上栀子树、十大功劳、山渣、栗类等都有危害,和茶树互相寄生。 1970年以来,我场在先锋工区、红卫工区、向阳工区、东方红工区茶树上先后发现蛇眼蚧危害,面积占全场茶园9％。近百亩先锋工区第二队危害极其严重,该队1971年早春把被害的茶树枯枝、虫枝剪下共有34担,严重地影响了当年产量。由于虫体小.不易发现,加上此虫第一代孵化期正值水蜜桃套袋、夏收夏种大忙季节,茶叶生产与其他生产劳动力比较紧张,容易疏忽,因此1970～1974年在先锋、红卫二个工区蔓延较快,对我场茶叶生产威胁很大。在场党委的领导下,我们从1970年开始.对蛇眼蚧进行了观察防治试验,现把七年来的观察及防治情况简报如下: 一、形态特征 My field is located in the southeast coast, all the year round warm, humid and rainy, mountain pine, bamboo, miscellaneous forest dense, conducive to the breeding of various pests, especially the harm of tea tree scale, mites rampant rampant in recent years, mountain up and down each other, such as turtle Scales, red larvae, tea pear scales and other gardenia tree in the mountains, the top ten merit, mountain residue, chestnuts and so have a hazard, and tea tree parasitic. Since 1970, our field has discovered snakes and coccids on tea plantations in Pioneer Work Area, Hongwei Work Area, Xiangyang Work Area and Dongfang Red Working Area, accounting for 9% of the total. Nearly a hundred acres of pioneer work area second team is extremely serious harm, the team in 1971 the victimized tea tree dead branches, cut off a total of 34 worms, seriously affecting the current production. Due to the small insect body is not easy to find, coupled with the pest of the first generation of hatching period when the peach bagging summer harvest summer busy season, the production of tea and other production labor more nervous and easy to neglect, so from 1970 to 1974 in Pioneer, Hongwei two work areas spread rapidly, a threat to my field of tea production. Under the leadership of the party committees present, we started from 1970. Observed on the snake eye scale prevention and control test, now seven years of observation and prevention and control briefings are as follows: First, the morphological characteristics
