ABSTRACT
Effect of synthetic repellents on acceleration of natural mounting in silkworm was studied. Natural mounting is a rational method of utilizing the negative geotaxis of the silkworm at the wandering stage. Five synthetic repellents viz., Phenol, Benzaldehyde, Formic acid, Cuminaldehyde and Benzoic acid were tested on silkworm bivoltine hybrid (CSR2 x CSR4). Among the five repellents tested viz., Phenol and Benzaldehyde at 0.10% & 0.05% concentrations showed 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 and post cocoon parameters. Thus, spraying of synthetic repellents at wandering stage accelerates mounting process in natural mounting without affecting cocoon and reeling characters.
Key words :
