  • Research:
    Multidisciplinary biosystematics, life-history traits and acaricide
    susceptibility in a complex of three closely related spider mites: Tetranychus hydrangeae, T.
    kanzawai and T. merganser

    The research work was focused on the systematic clarification between
    two closely related spider mites of Tetranychus hydrangeae and Tetranychus kanzawai. After
    detailed study on morphology, cross-breeding and molecular techniques, it was confirmed that
    T. hydrangeae is a synonym of T. kanzawai; and the species identified as T. hydrangeae is T.
    merganser. Life history parameters (rm) at different temperature regimes and acaricide
    mediate suppression with different acaricides were also studied. The intrinsic optimum
    temperature and temperature threshold were also discussed to compare their life-history
    parameters together with possible ways to control by using acaricides.
    Molecular-molecular biological techniques together with cross-breeding experiments might provide new, definitive data on the question of the true taxonomic status of the mites.
