| 摘 要： | 以苦豆子（Sophora alopecuroids L．）种子的甲醇提取物、水提取物及其7种生物碱单体和小菜蛾（Plutella xylostella）幼虫为试材，对生物源杀虫剂埃玛菌素进行增效作用研究。结果表明，7种生物碱单体对埃玛菌素增效比值为1．013～1．565。其中，苦豆碱和槐胺碱的增效作用最为明显，增效比值分别为1．565和1．413；而苦参碱和槐定碱对埃玛菌素的增效作用较差，增效比值仅为1．138和1．013，这2种生物碱单体对埃玛菌素仅表现出联合作用。苦豆子甲醇提取物和水提取物对埃玛菌素增效活性大于各生物碱单体，增效比值分别为3．443和2．027。

| Abstract: | Investigation on synergism action to emamectin against Plutella xylostella with extracts and alkaloids from seeds of Sophora alopecuroids L.was carried out.The results showed that synergistic ratio(SR) of seven alkaloids was from 1.013 to 1.563.And aloperine and sophoramin represented more obviously synergismaction whencombined withemamectin thanother alkaloidswith SR of 1.565 and 1.413 respectively,while SR of matrine and sophoradine was only 1.138 and 1.013 respectively.Both methanol and water extracts of S.alopecuroids exhibited a more significant synergism action than whole alkaloids with SR of 3.443 and 2.027 respectively. |
