Abstract

Abstract: Using isoclcctric focusing elcctrophoresis with olyactylamide, we analyzed the hcmolymph csterasc zymograms with nine silkworm strains of different descent and generation number.The result shows that all of the strains detect similar zymogram on the forth day after the post-molt feeding of the fifth inslar.We observed eighteen isozymc band all together which can be dcvide into four regions(EST Ⅰ,Ⅱ,Ⅲ,Ⅳ).The numbers and activities of isozymc bands are different according to the strains.The Ⅲ-3 band of five strains and the Ⅱ-2 band of four strains appear the sex-lankcd phenomenon.The Ⅲ-3 band appears male phenomenon and the Ⅱ -2 band with female phenomenon.

Key words: Silkworm, Sex, Hcmolymph, Estcrase isozyme
