The sericulture industry relies on silk production from Bombyx mori L., with significant economic implications. Ascorbic acid, a natural antioxidant, is of interest for enhancing silk yield. We investigated its impact on silkworm development, examining body weight, hemolymph protein, cocoon traits, and correlations. Local silkworm strains received four ascorbic acid concentrations, with consistent weight gain across races and a positive correlation between body weight and hemolymph ascorbic acid. Cocoon and shell weights showed strong correlations. Multivoltine races displayed varied 5th instar durations. Analysis of variance revealed temporal and genetic influences. Correlation coefficients showed diverse responses to ascorbic acid. Foodstuff parameters offered insights, and corpora allata size analysis revealed temporal responses. This study uncovers ascorbic acid's multifaceted effects on silkworm development, highlighting the role of genetics and the environment.
