ABSTRACT
The efficiency of synthetic repellents on natural mounting of silkworm, Bombyx mori L. was investigated. To improve the mounting process, five synthetic repellents viz., Phenol, benzaldehyde, Formic acid, Cuminaldehyde and Benzoic acid were tried on silkworm breed viz., PM × CSR2. The results revealed that, in benzaldehyde and formic acid at 0.50 and 0.05% treated batches, maximum number of larvae climbed on the mountages and built cocoons in the mountages. In turn, % of defective cocoon reduced and % of good cocoons were increased. Further, the synthetic repellents did not induce any detrimental affect on cocoon and post cocoon parameters.
Key words :
Bombyx mori , Self- mounting, Spinning of cocoon, Synthetic repellents.
