Abstract
By crossing experiments between selected diapause and non-diapause strains of Tetranychus kanzawai, we clarified the inheritance mode of diapause of the mites. The results showed that the "diapause" of T. kanzawai is a dominant character over "non-diapause" and that the diapause character is controlled by a simple Mendelian inheritance. This inheritance mode is different from that of T. urticae, in which the diapause is under polygenic control with a strong maternal effect involved.
