摘　　要： 利用4种入侵植物的水提取液及其与农药的混合液对假眼小绿叶蝉进行趋避和毒杀试验,结果表明,生药量为1g/mL的薇甘菊水提取液和马樱丹水提液对假眼小绿叶蝉趋避效最好;1 g/mL的薇甘菊水提取液与2.5%联苯菊酯20 mL 900倍液混合液对假眼小绿叶蝉的毒杀效果与2.5%联苯菊酯35 mL 900倍液的杀虫效果相当。4种入侵植物水提液对假眼小绿叶蝉的防治效果强弱依次为薇甘菊>马缨丹>南美蟛蜞菊>五爪金龙。 Insecticidal test on Empoasca vitis was carried out by using water-extracts of four invasive plants （Mikania micrantho, Lantana camara, Trilobate Wedelia and Ipomoea cairica） and their mixtures with biphenyl chrysanthemum ester in the tea gardens. Results showed that water extracts of 1 g/mL water extract from M. micrantha and L. camara had the best expulsive effects on E. vitis, and control effect of mixed liquor with 1 g/mL M. micrantha water-extract and 20 mL 2.5% biphenyl chrysanthemum ester （diluted 900 times） was equal to that of 35 mL 2.5% biphenyl chrysanthemum ester （diluted 900 times）. Control effects of four water-extracts on E. vitis from strong to weak was as follows： M. micrantha, L. camara, T. wedelia, 1. cairica.
