Silkworm is a lepidopteran insect which produces the very important protein called silk, the “Queen of Textile” through the pro called sericulture. B. mori (L.) completes its life cycle through passing different stages of development following 1st, 2nd, 3rd, 4th & 5th instar, 5th instar is the final instar stage and it is the mature stage of larval period. Yellow coloured ripped 5th instar forms a cocoon from which adult B. mori comes out. Soon after adults start mating and after 24hrs of mating females start laying eggs which further hatched into 1st instar larvae and cycle goes on. In this study fortified mulberry leaves with Giloy and Ashwagandha extract were taken to observe the different biological activities of B. mori. Here Giloy and ashwagandha extracts were fed to B. mori which significantly enhanced various aspects of silkworm development & productivity. Silkworm, B. mori were reared and exhibited faster growth with notable shorter larval & pupal duration in comparison to control mulberry leaves. In addition, B. mori showed high moth emergence rate, increased fecundity & hatching % at 5% Giloy extract treatment in comparison to control and other extract treatments.
