Isozymes of alpha- and Beta-esterase were analyzed in four selected races of univoltine (B38P), bivoltine (NB18 and SF19) and multivoltine (C. michi) by employing polyacrylamide gel electrophoretic technique (PAGE). Racial differences as a reflection of ontogenic differentiation of the multi-banded system in the races under study were identified, although the trend of differential activity of the esterase(s) follows a specific pattern in all the races. Certain differences are also known between alpha- and Beta-esterases when Beta-esterase is more prominent and exhibits higher activity
