7.This paper is a review on insect diapause,with special emphasis on physiological biochemical mechanism and gene expression,regulation of diapause hormone (DH)
8.Diapause hormone (DH) is the hormone that can induce diapause of egg. DH activity may be widely distributed, only in Bombyx mori (silkworm), among the insects studied, has this peptide been captured as a regulator of diapause (Denlinger,2002).
9.In population of T. cinnabarinus the percentages of diapause females were 93.85% and 93.58% in February and March, respectively, when they did not terminate the diapause.
