Active collection of new resources and systemic management of gene resources on the conservation are necessary, since the Convention on Biological Diversity came into effect in 1993, countries have tried to protect their gene resources and avoid exchange of resources for national profit. Our lab. performs studies on races breeding of conserving resources, on base materials and on the utilization of availability of these resources. And also our laboratory conducts safe conservation of 321 exiting silkworm races and collection of various gene resources. In the future, we collect and conserve not only commercial silkworm genes but also wild silkworms and other rare insect species. Systemic investigation and arrangement of basic data also will be conducted for contribution to the development of insect industrialization in the 21st century.
