Abstract:
In the present study, quantitative and qualitative changes in protein profile of different tissue of larvae, pupae, adult and eggs of Tasar silkworm Antheraea mylitta Drury was investigated. Stage and age dependent variation in protein concentration and SDS-PAGE protein profile of 36 and 64 kDa protein was observed in different tissue. The concentration of protein was recorded higher in eggs laid by fresh moth than 3 days old moth and significant variation was also noticed in normal and depressed eggs. Interestingly, substantial changes in SDS-PAGE protein profile was observed in normal and depressed eggs and eggs laid by fresh moth than 3 days old moth. Haemolymph and midgut protein concentration was recorded higher in 3rd and 5th instar feeding larvae and in 4th instar mature larvae. Concentration of protein in the haemolymph of pupae before the brain window becomes opaque was higher in both the sexes than opaque stage. Fat body protein concentration in larvae showed increasing trend from 3rd to 5th instar larvae and it was higher in pupae after the brain window becomes opaque and fresh moth. In addition, higher protein concentration was recorded in gonads of pupae after the brain window becomes opaque and in reproductive organs of fresh moth. Present findings would promote to further understand the precise reason for depression of eggs and changes in protein profile in different tissue of A. mylitta.
