Racial Differentiation Of A- And B-Esterase Isozymes In Selected Races Of Silkworm Bombyx Mori L.

Rampoore S. Umakanth | Nidaghatta B. Krishnamurthy

Abstract:

Isozymes of a- and B-esterases were analyzed in four selected races of univoltine (B38P), bivoltine (NB and SF19) and multivoltine (C. nichi) by employing polyacrylamide gel electrophoretic technique (PAGE). Racial differences as a reflection of ontogenic differentiation ofthe 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 a- and ?-esterases where ?-esterase is more prominent and exhibits higher activity.
