K. Goka, Mode of inheritance of resistance to three new acaricides in the Kanzawa spider mite, Tetranychus kanzawai Kishida (Acari : Tetranychidae), EXP APPL AC, 22(12), 1998, pp. 699-708
The genetics of resistance to three new types of acaricide - tebufenpyrad,
fenpyroximate and pyridaben - was studied by crossing a resistant (R) with
a susceptible (S) strain of Tetranychus kanzawai Kishida. The resistance ra
tios calculated from the LC(50)s of the R and S strains were 97, 1265 and 1
34 for tebufenpyrad, fenpyroximate and pyridaben, respectively. The respons
es to the three acaricides in F-1 females from reciprocal crosses between t
he R and S strains showed that the modes of inheritance of resistance to te
bufenpyrad, fenpyroximate and pyridaben were intermediate, incompletely dom
inant and completely recessive, respectively. Furthermore, the responses of
F-2 females from the reciprocal crosses indicated that the resistance to t
he three acaricides was under monogenic control. Exp Appl Acarol. 22: 699-7
