STUDIES ON THE QUANTITATIVE ESTIMATION OF AMYLASE ACTIVITY IN SELECTED LARVAL MUTANTS OF SILK WORM BOMBYX MORI .L ON TWO MULBERRY VARIETY
Four larval mutant namely Knobbed, Zebra, Pere and Ursa were selected for the investigation. The digestive juice and haemolymph were collected from fifth instar larvae from 1stto6th day and the samples were subjected to spectrophotometric analysis for amylase activity.The recorded O.D. values (at 525 nm) were converted into maltose released .
Accordingly, the results clearly indicate that the amylase activity get enhanced with the increase in number of feedings along with the advancement of day wise. Zebra fared better than the other three mutants followed by Knobbed fared better and larvae fed with V1 performed better than those fed with S36 mulberry variety in both the samples.
