Impact of reeling wastewater applicated Mulberry leaves on economic parameters of silkworm (Bombyx mori. L)

Abstract:

The rearing of silkworm was conducted by fed with wastewater irrigated Mulberry leaves at the Department of Sericulture, Forest College and Research Institute, Mettupalayam during 2018-19. Silkworm larvae fed with reeling wastewater irrigated leaves showed maximum larval weight of 3.70 g and highest effective rate of rearing of 97.78%. The more cocoon weight of 1.77 g, shell weight of 0.39 g and cocoon shell ratio of 22.03% was recorded at 25% concentration of wastewater. The reeling parameters like filament length of 1350.37 m, filament weight of 378 mg, denier of 2.59, raw silk percentage of 23.25% and silk productivity of 7.0 cg/day were also observed at 25% concentration of reeling wastewater application. Among the treatments, reeling wastewater was significantly different when compared to other treatments.
