ABSTRACT
Effect of synthetic repellents in acceleration of natural mounting methods of the silkworm (Bombyx mori L.) was studied. Five synthetic repellents viz., Phenol, Benzaldehyde, Formic acid, Cuminaldehyde and Benzoic acid were tested on the CSR2 x CSR4 hybrid. Among the five repellents tested, viz., Phenol and Benzaldehyde at 0.1 and 0.05% concentrations showed more improvement in the percentage of larvae climbed and formed the cocoon on the mountages. Further, it was also observed that there was no bad effect on cocoon parameters.
Key words :
Bombyx mori, Natural-mounting, Spinning of cocoon, Synthetic repellents.
