Abstract: The present study is based on the impact of BmNPV infection on physiological and biochemical parameters of Bombyx mori administrated with botanicals (Plectranthus amboinicus and Psoralea corylifolia). The study result revealed that activities of alkaline phosphatase and amylase enzymes in multivoltine silkworm breeds in response to botanical, higher enzyme activity was recorded for untreated control in all the breeds, Nistari (7.10 μg/ 100 μl, 1471.52), C. Nichi (6.60μg/ 100μl, 1400.29), Tamil Nadu White (6.20μg/ 100μl,1190.20) followed by P. corylifolia for Nistari (5.00 μg/ 100 μl, 1190.28), C. Nichi (4.65μg/ 100μl,825.35), Tamil Nadu (5.25 μg/100μl, 900.12) and P. amboinicus for Nistari (5.23μg/ 100μl, 1201.99), C. Nichi (4.95 μg, 735.20), Tamil Nadu White (4.90 μg/100 μl, 885.11). Studies on biochemical parameters of multivoltine breeds to botanical treatment revealed that untreated control recorded the highest content of carbohydrates, protein, lipid, and uric acid in Nistari (9.90mg/ ml, 97.45mg/ ml, 5.12mg/ g, 4.70mg/ g of fresh excreta), C. Nichi (8.92, 90.00, 4.90, 4.90) and Tamil Nadu white (9.80, 93.11, 5.35, 4.60) followed by P. amboinicus and P. corylifolia and both were found on par.
