摘　　要：假眼小绿叶蝉是小绿叶蝉的优势种群,也是陕西茶叶主要的害虫之一。笔者研究了0.6%苦参碱水剂、1.3%苦参碱水剂、1.5%除虫菊素水乳剂、茶蝉净和0.5%藜芦碱可溶性液剂等5种植物源农药对假眼小绿叶蝉的田间防效。结果表明,0.6%苦参碱水剂、1.3%苦参碱水剂和1.5%除虫菊素水乳剂3种药剂对假眼小绿叶蝉几乎无防治效果。茶蝉净和0.5%藜芦碱可溶性液剂对假眼小绿叶蝉表现出了良好的防效,施药1 d后的防效分别为57.0%和32.4%,施药3 d后的防效分别为63.2%和60.2%,施药7 d后的防效分别为86.9%和70.6%。研究结果为田间防治茶叶主要虫害假眼小绿叶蝉提供了新的药剂选择。Empoasca vitis Gothe is the dominant population of the Empoasca flavescens Fab. It is also the main pest infesting tea trees in Shaanxi Province. Five plant-derived pesticides including 0.6% matrine aqueous solution (AS), 1.3% matrine aqueous solution (AS), 1.5% pyrethrin emulsion in water (EW), tea cicada killer and 0.5% veratrine soluble liquid agent (SL) were used to treat tea trees infested with . E.vitis to observe their field efficiency against E.vitis . The result indicated that 0.6% matrine AS, 1.3% matrine AS and 1.5% pyrethrin EW almost had no control effect against E.vitis . Tea cicada killer and 0.5% veratrine (SL) showed a good control effect against the pest, and had respective control effects of 57.0% and 32.4% after 1 day of treatment, 63.2% and 60.2% after 3 days of treatment, and 86.9% and 70.6% after 7 days of treatment. These results provide a new choice of bioinsecticide for the prevention and control of the main insect pest E.vitis in the field.
