Artificial Hatching of Silkworm Eggs after chilling
Artificial Hatching of Silkworm Eggs after chilling
Mian Muhammad Muslim
ABSTRACT
The silkworm eggs of locally developed F1 hybrid were
laid in spring 1989 at 26°C, stored at a temperature of
22 to 26°C for a period of 61 days and refrigerated at a
temperature of 4 to 6°C for 93 days. These were treated
subsequently with HCL solution of different
concentrations at 48°C for a period of 6 minutes for
their artificial hatching in autumn. Treatment with 20%
HCL solution was found to be most suitable for obtaining maximum useful hatchability of 92.3% under local
conditions.
