摘　　要：茶小绿叶蝉(Empoasca pirisuga Matumura)是茶园中,特别是绿色食品茶园及有机茶园中危害较重且难以防控的害虫。为了筛选出绿色食品茶园及有机茶园中适合防治茶小绿叶蝉的生物农药,笔者选择了30%茶皂素AS、0.5%苦参碱AS、0.5%印楝素EC(力胜)、400亿个孢子/g茶将军WP(球孢白僵菌)四种生物农药进行单剂或复混剂共五个处理进行试验,结果表明:各处理对茶小绿叶蝉的防治效果均较好,最佳防效达100%,A与C及C与D药后21 d在P<0.05的显著水平上均存在差异显著性。Tea green leafhopper is a serious pest that is difficult to control in tea plantation, especially in pollution - free tea garden and organic tea garden. In order to screen a suitable biological pesticide against green leafhopper for pollution- free tea garden and organic tea plantation, four biological pesticides, 30% tea saponin AS, 0.5% matrine AS, 0.5% neem EC （Li Sheng） and 40 billion conidia/g chajiangjun WP （Beauveria bassiana）, were used as single or mixed agents for five treatments to carry out the experiment. The results showed that there was a good control effect on the green leafhopper for all the treatments, and the optimum control effect had reached 100%. A significant difference was observed using A and C after 2 ldays, while there was a significant difference using C and D after 21 days.
