Abstract: Electro-focusing PAGE was used to study esterase isozyme of 5 species of aphid that appeared frequently on vegetables, Aphis robiniae Zhang, Aphis gossypii Glover, Lipaphis erysimi (Kaltenbach), Semiaphis heraclei (Takakashi) and Myzus persicae (Sulzer). Each species of aphid had its characteristic electrophoretic pattern, according to which, a biochemical key was made. And a brief analysis of polymorphism that appeared in electrophoretic patterns of Lipaphis erysimi (Kaltenbach) was also made.

Key words: aphid, isozyme, biochemical key

摘要: 应用聚丙烯酰胺等电聚焦凝胶电泳分析了蔬菜上常见5种蚜虫的酯酶同工酶,即刀豆黑蚜(Aphis robiniae Zhang )、棉蚜(Aphis gossypii Glover)、萝卜蚜(Lipaphiserysimi(Kaltenbach) )、胡萝卜微管蚜 (Semiaphis heraclei (Takakashi) ) 和桃蚜(Myzus persicae (Sulzer))。5种蚜虫各有自己的特征酶谱,根据同工酶酶谱的差异,作出了5种蚜虫的生化检索表。萝卜蚜和刀豆黑蚜的酯酶酶谱表现为多态现象,对萝卜蚜的多态性进行了初步讨论分析。
