A. Takafuji et K. Goka, Mode of diapause inheritance in the Kanzawa spider mite, Tetranychus kanzawai (Acari : Tetranychidae), APPL ENT ZO, 34(3), 1999, pp. 299-302
By crossing experiments between selected diapause and non-diapause strains
of Tetranychus kanzawai, we clarified the inheritance mode of diapause of t
he mites. The results showed that the "diapause" of T. kanzawai is a domina
nt character over "non-diapause" and that the diapause character is control
led by a simple Mendelian inheritance. This inheritance mode is different f
rom that of T. urticae, in which the diapause is under polygenic control wi
th a strong maternal effect involved.
