| Research Abstract |
Survey and genetical examinations on the domestic silkworm, Bombyx mori, and the wild silkworm, Bombyx mandarina, were carried out in some countries put in plactice moriculture, sericulture and silk industry.
We visited several institutions, universities, companies and farmhouses in Thailand and India, and we confirmed many tropical strains of polyvoltine silkworm, which had properties of resistances to high temperature and to pebrine disease. Many varieties of these strains were not recognized in any other countries. These strains should be thought valuable property in sericultural science. In China, many strains and many races of the domestic silkworm had been preservated at sericultural institutions and universities in like manner of Japan. In Uzbekistan, senicultural production were held only one season a year under strict weather conditions. The keeping strains of silkworm were only univoltine. The silkworm strains of economic valueless such as mutants were not preserved in Uzbekistan. In Brasil, the technique of cocoon production was imported from Italy and it started in 1927. However, the silkworm of Italian strain could not detect. In Korea where sericulture has been over, the silkworms of univoltine and trimolter were preserved yet.
