Abstract: The experiment was conducted at Department of Agricultural Entomology, College of Agriculture Latur, during December- January 2012-2013, in randomized block design with ten treatments and three replications. Disease free layings of silkworm hybrid were utilized as experimental material.The treatments were leaves of S-13 (100%), V-l (100%), S-1635 (100%), S-13+V-1 (60 % +40%), S-13+V-1 (40% + 60%), S-1635+V-1 (60%+ 40%), S-1635+V-l (40 % +60%), S-13+S- 1635 (60 % + 40%), S-13+S-1635 (40% + 60%), S-13+V-1+S-1635 (in equal proportions). Out of ten treatments the highest weight of ten matured larvae, single cocoon weight, single shell weight, cocoon yield/ 10,000 larvae brushed, cocoon filament length, hatching percentage, fecundity and effective rate of rearing to the extent of 39.17g, 1.63g, 0.304g, 15.53kg, 970m, 93.77 per cent, 476 and 97.23 per cent, respectively were recorded by the larvae fed on 100 per cent leaves of mulberry variety V-1. The significantly lowest incidence of silkworm diseases was observed in the larvae fed on 100 per cent leaves of V-l (2.97 per cent) and highest incidence of disease (5.03 per cent) was observed in larvae fed on leavelT of S-13 (100%). The observations were recorded on the biology and different economic traits of bi x bivoltine silkworm hybrid. The biological parameters and all the economic traits of silkworm were found to be superior in the case of those larvae which were reared on 100% leaves of V-l, compared to 100 % leaves of S-13 (standard check).
