Abstract

The experiment was conducted to study the impact of four bed disinfectants on mulberry silkworm multivoltine hybrid mulberry silkworm [NISTARI × (SK6×SK7)] reared on C2038 variety in Kishanganj district of Bihar. Mulberry silkworm treated with bed disinfectant Labex@ 5g/sq. ft. ½ an hour before feeding showed significantly higher result in terms of single cocoon weight ((1.56 g), single shell weight (0.62 g), SR percentage (39.74 %), filament length (790.67 m), NBFL (790.67 m), denier (2.54), raw silk filament weight (0.23 g), renditta (4.57), in comparison to Vijetha, Sericillin and Amla powder while lower values were recorded in control batch.

Conclusion

The success of sericulture industry depends upon several factors of which the impact of the environmental factors such as biotic and abiotic factors is of vital importance (Gautam et al., 2022). Among the abiotic factors, temperature plays a major role on growth and productivity of silkworm, as it is a poikilothermic (cold blooded) insect Benchamin and Jolly (1986). Mulberry silkworm treated with bed disinfectant Labex @ 5g/sq. ft. ½ an hour before feeding showed significantly higher result in terms of single cocoon weight, single shell weight, SR percentage, filament length, NBFL, denier, raw silk filament weight, renditta in comparison to Vijetha, Sericillin and Amla. So, it is recommended to follow the disinfection by Labex for better post cocoon parameters in Bihar and eastern part of India.
