摘　　要：茶小绿叶蝉为广布性昆虫,分布遍及全国各大茶区,是对我国茶树为害最严重的害虫之一。为了探讨茶小绿叶蝉的防治措施,研究了机动和电动2种机型喷雾结合5%鱼藤酮乳油、5%云菊天然除虫菊素乳油、0.2%苦皮藤素乳油和0.6%苦参碱内酯水剂对茶小绿叶蝉的田间防治效果。结果表明:4种药剂对茶小绿叶蝉有较强杀伤力,能迅速降低害虫田间虫口数,药后1~21 d平均防效为77.69%~85.39%;4种药剂中以0.6%苦参碱内酯水剂防治效果最好,且机动喷雾防治效果较电动喷雾好;选择机动喷雾器交替使用0.6%苦参碱内酯水剂、0.2%苦皮藤素乳油、5%云菊天然除虫菊素乳油3种植物源药剂可有效、可持续性防治茶小绿叶蝉。Tea green leafhopper is a widely distributed insect, which is distributed throughout the major tea areas in China. It is one of the most serious pests to tea trees in China. In order to explore the control measures of tea green leafhopper, the field control effects of mobile and electric spray combined with 5% rotenone EC, 5% natural pyrethrin EC, 0.2% celastrin EC and 0.6% matrine internal fat agent on tea green leafhopper were studied. The results showed that the four insecticides had strong lethality to the tea green leafhopper, and could rapidly reduce the number of insect pests in the field. The average control effect was 77.69%~85.39%from 1 day to 21 days after the application.Among the four insecticides, 0.6% matrine was the best, and the control effect of mobile spray was better than that of electric spray.The alternative use of 0.6% matrine internal fat agent, 0.2% celastrin EC and 5% natural pyrethrin EC in mobile spray can effectively and sustainably control tea green leafhopper.
