摘要
以苦豆子 7种生物碱单体和小菜蛾 Plutella xylostella幼虫为试材 ,对分属于有机磷酸酯、氨基甲酸酯和生物源杀虫剂 (阿维菌素 )的 4种杀虫剂进行了增效作用测定。结果表明 :7种生物碱对辛硫磷的增效比值为 0 .82～ 1.96倍 ;对丙溴磷的增效比值为 1.10～ 2 .15倍 ;对灭多威的增效比值为 1.2 3～ 1.84倍 ;对阿维菌素的增效比值为 1.6 3～ 5 .4 2倍 (72 h)及 0 .96～ 2 .96倍 (96 h)。
The synergism of 7 alkaloids from a leguminous plant , Sophora alopecuroids, to four insecticides which belong to organophosphorus compounds,carbamate insecticides and natural chemicals.The results showed that the synergic ratio of seven alkaloids to phoxim was the range of 0.82～1.96 folds,1.10～ 2.15 folds to profenofos,1.23～1.84 folds to methomyl and 1.63～5.42 folds (72 h), 0.96～2.96 folds(96 h) to abamectin respectively. The synergic mechanisms of the alkaloids to insecticides were discussed.
