摘　　要：本文研究了川滇无患子果实不同部位提取物对小菜蛾、甘蓝蚜的生物活性,以及川滇无患子果皮提取物与吡虫啉、阿维菌素复配后的混合物对甘蓝蚜、小菜蛾的生物活性。研究结果表明:川滇无患子果皮提取物对小菜蛾幼虫有较好的致死率,而且对其化蛹和羽化也有较好的抑制作用;在对蚜虫致死作用上,川滇无患子果皮、果仁提取物对甘蓝蚜都有较好的生物活性。川滇无患子果皮提取物与吡虫啉复配后能明显提高吡虫啉对甘蓝蚜的生物活性,但对提高阿维菌素对小菜蛾的生物活性不明显。In this experiment, the bioactivity of the extracts from different parts of Sapindus delavayi fruits to Plutella xylostella and Brevicoryne brassicae and the bioactivity of imidacloprid or abamectin to P. xylostella and B. brassicae when mixed up with the extractions of S. delavayi ＇ s pericarp were studied. The findings indicated that the pericarp extraction had a good lethal rate to P. xylostella larvae and also had a good inhibitory action to its pupation and eclosion. Both the pericarp and kernel extractions of S. delavayi had good lethal bioactivity to B. brassicae. The bioactivity of imidacloprid to B. brassicae could be significantly enhanced when the S. delavayi pericarp extraction mixed up with imidacloprid, which did not obviously improve the bioactivity of abamectin to P. xylostella.
