Abstract:
Fortification of silkworm host plant leaves is a technique of recent application in sericulture research to increase its economic value. In the present investigation, the silkworm bivoltine double hybrid FC₁ × FC₂ [(CSR₆ × CSR₂₆) × (CSR₂ × CSR₂₇)] was reared on mulberry leaves fortified with proteins namely drone brood, protinex and their combinations to study its effects on larval growth parameters and on economic growth parameter called Gland-Body Ratio. Protinex (10%) concentration caused the significant influence on larval body length, larval body weight and larval body perimeter of silkworm in terms of Overall Growth Rate by 46.56, 295 and 48.54 per cent with Compound Periodical Growth Rate of 6.32, 24.58 and 6.52 per cent, respectively. Moreover, in protinex (10%) and drone brood (6%) concentrations the impact on Gland-Body Ratio was found more pronounced when compared to other concentrations.
