摘 要：
将苦豆子甲醇和水提取物分别与埃玛菌素混合,在室内测定了两混合物对小菜蛾生长发育和繁殖的影响.结果表明:苦豆子甲醇提取物+埃玛菌素和苦豆子水提取物+埃玛菌素对小菜蛾3龄幼虫口服毒力明显高于埃玛菌素,其LC50值分别为0.19、0.32和0.51 mg.L-1;用两混合物以及埃玛菌素亚致死剂量处理3龄幼虫,试虫化蛹率、羽化率和成虫的繁殖力均呈现明显不良影响.

摘 要：
In this paper,the methanol-and water extracts of Sophora alopecuroids were applied respectively with emamectin,to study their effects on the growth,development,and fecundity of diamondback moth Plutella xylostella.The results showed that the oral toxicity of the mixtures to the 3rd larvae of P.xylostella was much higher than that of emamectin,with the medium lethal concentration(LC50) of methanol extract plus emamectin,water extract plus emamectin,and emamectin being 0.19,0.32 and 0.51 mg·L-1,respectively.The pupated percentage,emergence percentage,and fecundity of P.xylotella were obviously negatively affected after treated the 3rd larvae with sub-lethal dosage of the mixtures and emamectin.
