AbstractThe embryonic diapause of the silkworm, Bombyx mori, is induced by the diapause hormone (DH) which is secreted from the suboesophageal ganglion of pupae. The diapause nature of bivoltine strains uses environmental stimuli as the initial signal to determine the diapause nature. The experiments showed that DH gene expression is a direct response to the environmental stimulus, such as high incubation temperature. The cDNA from the embryonic stage was cloned and sequence analysis showed the cDNA encoding DH. Expression patterns of the DH gene in embryonic stage are different at incubation temperatures 15°C and 25°C , suggesting that the incubation temperature as an environmental signal is kept within the body to control the DH gene expression at the pupal stage, so that the embryonic diapause of next generation can be determined.
