Evidence of a sex linked diapause response in papilio glaucus subspecies and their hybrids


Physiological Entomology 12(2): 181-184
Evidence of a sex linked diapause response in papilio glaucus subspecies and their hybrids
Pupal diapause in the eastern tiger swallowtail, Papilio glaucus L., is obligatory or facultative depending on subspecies. The southern subspecies, P. g. glaucus has a facultative diapause, induced by a larval exposure to short photoperiods. In the northern subspecies, P. g. canadensis, diapause is obligatory, occurring in each generation. F1 hybrids inherit the diapause response of their father or respond differently from either parent. The incidence of diapause in hybrids was associated with sex, indicating that the diapause response may be determined by an X-linked gene.
