摘　　要：The sericulture industry plays a very important role in our national economy. Silkworm (Bombyx mori) is always regarded as a model animal and biological reactor. There have been detailed studies on the structure, expression and control and molecular evolution of silk genes. However, few, if any, reports are available on the localization of structural genes in silkworm by molecular cytogenetics. The present experiment has tentatively localized the Fib-H gene at the distal end of the 25th linkage group, namely at the 25-0.0 position, and verified that Fib-H has only one locus, thus providing a temporary solution to the problem about its localization.The sericulture industry plays a very important role in our national economy.
