Studies were carried out on the impact of supplementation of Zea mays flour on silkworm Bombyx mori belonging to double hybrid variety (PFD). The 3 rd ,4 th 5 th instars larvae were feed with leaves supplemented with different concentrations of Zea mays flour. Maximum larval weight was observed in 5 th instar larvae in 10% Treatment (4.59±0.31g ) and 5% Treatment (3.98±0.23g ) as compared to the control (3.13± 0.14g ).Mulberry leaves treated with Zea mays flour protein (10%)fed larvae recorded a maximum cocoon weight (2.32±0.07g), pupal weight (1.53±0.12g) shell weight (0.42±0.02g) , shell ratio (24.55±0.62%) silk filament length (851.11±6.94m) silk filament weight (0.51±0.04g). Shell ratio in this treatment (10%) showed an increase of 18.38 % over control filament length 21.64% . Larvae fed with mulberry leaves enriched with Zea mays flour protein showed significant enchancement in economic characters of Bombyx mori was traced.
