Evaluation of Different Bed Disinfectants on Economic Traits of Bivoltine Hybrid Mulberry Silkworm (SK6×SK7) in Kishanganj District of Bihar

The present experiment was carried out in the Kishanganj district of Bihar to assess the impact of various disinfectants on the bivoltine cross mulberry silkworm (SK6×SK7) reared on the C-2028 variety. The cross between SK6 and SK7 is considered a promising combination for silk production in East and North East region used for commercial silk production and egg production. Among the disinfectants tested, treating the mulberry silkworms with Vijetha @5g per square foot, half an hour before feeding, yielded the most favourable outcomes. This treatment resulted in higher measurements for parameters such as single cocoon weight (1.94 g), single shell weight (0.61 g), SR percentage (31.74%), filament length (987.7 m), NBFL (non-breakable filament length) (987.7 m), denier (2.56), raw silk filament weight (0.27 g), and renditta (2.90). In contrast, the control group exhibited lower values for these parameters. The results showed that Vijetha treatment had a positive impact on the quality and characteristics of the produced silk cocoons compared to the other disinfectants viz Labex, Sericillin, and Amla powder and the control group.
