Effect of different bed disinfectants on life-cycle of double hybrid mulberry silkworm (Bombyx mori L.)

Abstract

The significantly lowest pupal duration (10.07 days), highest moth emergence (96.5 per cent) and fecundity (565.94 eggs) were recorded in the use of bed disinfectant Vijetha @ 5g/ sq. ft. The lowest larval duration (22.03 days) and highest hatching per cent (96.31 per cent) also recorded in the use of bed disinfectant Vijetha @ 5g/ sq. ft. The significantly highest larval duration (24.43 days), pupal duration (11.65 days) and significantly lower moth emergence (85.95 per cent), hatching percentage (84.84 per cent) recorded in the untreated control. The lowest fecundity (439.17 eggs) were recorded in the untreated control.
