Silkworm Which Does Not Make Cocoons
A silkworm breed was developed and given a name of `Hachojam'. This breed does not make the usual cocoons. Pupae yield per 10,000 individuals of the breed was on average 24% higher than that of cocoon-producing breeds. Because the effort for cocoon cutting was not required with this breed, the labor of producing Paecilomyces japonica could be reduced by 34%.
Medicinal Substances from Pupae
This breed is expected to be useful for the production of substances to lower blood glucose level, interferon, and functional food materials, for which cocoon making is unnecessary.
