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.
