Phytoseiid mite populations were collected on citrus groves, or windbreaks composed mainly of Yew podocarpus or Japanese cedar around the citrus groves, and on grapevines in glasshouses and vinyl-houses in western Japan. Susceptibilities of the phytoseiid mite populations to methidathion, carbaryl, salithion and maneb were compared. Susceptibilities to methidathion of the Amblyseius eharai AMITAI et SWIRSKI populations collected from Kawakami, Yahatahama and Higashino, Matsuyama in Ehime Prefecture and other three habitats were low. The resistance factor at the LC_<50> value of the Higashino, Matsuyama population (R) to the susceptible one (S) was 9.3 (13.0ppm/1.4ppm). Susceptibility to methidathion of the A. sojaensis EHARA population collected from Yakura, Iyo (R) in Ehime Prefecture was the lowest, and the resistance factor was 6.4 (43.0ppm/6.7ppm). In A. longispinosus (EVANS), the susceptibilities to methidathion were comparatively high. Susceptibilities to carbaryl of the A. eharai populations collected from Higashino, Matsuyama (LC_<50>=82.0ppm) and other seven habitats were low. Susceptibility of the A. sojaensis population from Yakura, Iyo (R) to carbaryl was low, and the resistance factor was 4.7 (53.4ppm/11.3ppm). In A. longispinosus (EVANS), the susceptibilities to salithion of the populations collected from Ichinomiya, Okayama, and Akitsu, Hiroshima Prefecture were low, and the LC_<50> values of the two populations tested were nearly 400ppm.
