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%。

摘  要:
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(LC50) 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.
