Assessing the Effects of Combined Industrial and Urban Sewage Water on Food Utilization in the Silkworm Bombyx mori L.

Aim/Background: Sericulture is a crucial agro-based sector affected by environmental conditions, especially the quality of mulberry leaves, which serve as the principal food supply for silkworms (Bombyx mori). Materials and Methods: This study evaluates the effects of combined industrial effluents and urban sewage water on silkworm food utilisation and metabolic efficiency. Mulberry plants (Morus alba) were grown in pots utilising different concentrations (25%, 50%, 75% and 100%) of wastewater, while control plants were watered with borewell water. FC1×FC2 bivoltine silkworm larvae were cultivated under regulated laboratory conditions and their nutritional characteristics were assessed by gravimetric methods. Results: Findings demonstrate that moderate effluent exposure (75%) augmented eating and metabolic activity, resulting in improved food intake, absorption and conversion rates. At 100% effluent concentration, metabolic stress resulted in prolonged larval duration, diminished digestive efficiency and decreased conversion rates, signifying hazardous consequences. The diminishing efficiency of food conversion underscores possible threats to silk output and quality. Conclusion: The results highlight the necessity for pollution regulation in sericulture areas to alleviate environmental strain and guarantee sustained silk production. Implementing pollution management measures is essential for maintaining silkworm health and ensuring industrial sustainability.
