Dietary supplementation of ascorbic acid was found to be effective in modifying the composition of essential biomolecules. A relative investigation on effects of exogenous dietary supplementation of 0.2% ascorbic acid on the fifth instar larvae of silkworm, Bombyx mori exposed to a high thermal stress of range 40 ± 2 °C was carried out in the lab-set conditions. The observed elevation in various biomolecules, viz., DNA, RNA, protein, lipids, and carbohydrates were quantified in both the thermal stress-induced test groups and in the control, set aside. The test results so obtained were proven to be statistically significant. The present study reveals that foliar supplementation of ascorbic acid has been effective in positively-modulating the biochemical performance in larvae exposed to thermal stress. Moreover, the study also uncovers the possibilities of ascorbic acid as a potential candidate, capable of facilitating the production of good quality cocoons, from larvae exposed to thermal stress.
