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.

在一些国家进行了家蚕和野桑蚕的调查和遗传学研究，并访问了泰国和印度的一些研究机构、大学、公司和农户，证实了许多具有耐高温和抗微粒子病特性的多化性家蚕热带品系。这些菌株的许多变种在任何其他国家都没有得到承认。这些品系在蚕业科学上是有价值的财产。我国的蚕业研究机构和大学也曾象日本那样，对许多家蚕品系和品种进行了鉴定。在乌兹别克斯坦，在严格的气候条件下，一年只进行一个季节的老龄化生产。养蚕品种均为一化性品种。没有经济价值的蚕品种，如突变体，在乌兹别克斯坦没有保存。巴西从意大利引进蚕茧生产技术，始于1927年。但意大利品系的家蚕不能检测到。在蚕业已经结束的朝鲜，一化蚕和三眠蚕还保存着。
