摘　　要：研究了黄皮种子甲醇提取物对茶黄蓟马(Scirtothrips dorsalis Hood)的驱避和触杀作用。结果表明:黄皮种子甲醇提取物对茶黄蓟马有较强的驱避活性,在浓度为20 g/L时,12 h和24 h对茶黄蓟马的驱避率分别为92.86%和89.91%;另外,提取物对茶黄蓟马有一定的触杀作用,处理后12 h和24 h对茶黄蓟马的致死中浓度(LC50)分别为16.60 g/L和12.85 g/L。各萃取相中石油醚相的活性最高,质量浓度为5 g/L时,石油醚萃取物对茶黄蓟马24 h后的校正死亡率为49.37%。The repelling and contact actions of the methanol extract from Clausena lansium （Lour.） Skeels  seeds against Scirtothrips dorsalis were investigated. The results showed that the methanol extract had an extremely strong repelling activity. The percentages of repellency of the extract against S. dorsalis at 20 g/L were 92.86% and 89.91% after 12 and 24 h, respectively. In addition, the extract displayed contact activity to some extent. The medium lethal concentrations （LC50） of the extracts to S. dorsalis were 16.60 g/L and 12.85 g/L after 12 h and 24 h, respectively. The bioactivity of petroleum ether phase of C. lansium seeds was the highest, with an adjusted mortality of 49.37% after 24 h.
