Abstract

The proteins and esterase isoenzymes from Anopheles stephensi were analyzed by polyacrylamide gel electrophoresis. Changes in proteins and esterase isoenzyme patterns during developmental stages were studied. A few specific protein bands were present esp. in the third instar larval stage. In most strains, eggs showed only one esterase band. During the larval development many bands were gradually formed and most anodal bands were lost upon pupation. The adults showed differences in intensity and mobility exhibiting sexual dimorphism. The protein and esterase isoenzyme patterns of organophosphate (fenthion, methyl parathion and malathion) resistant and susceptible strains during developmental stages were compared. The zymogram and relative mobility showed variation in the no. of intensity of proteins and esterase bands in the resistant strains as compared to the susceptible strains.
