Anopheles minimus larvae from Ishigaki Island, and An. saperoi and An. sinensis larvae from Okinawa Island, Okinawa Prefecture, were tested for insecticide susceptibility. The LC_<50> values of organophosphates (malathion, fenitrothion, dichlorvos and temefos) examined were low for An. minimus. Against p, p'-DDT, 6 organophosphates and permethrin tested, An. saperoi showed low LC_<50> values. For An. sinensis, the LC_<50> values to 5 of 7 organophosphates were high, being 19.2ppm to malathion, 15.5ppm to fenitrothion, 9.7ppm to dichlorvos, 8.3ppm to diazinon and 73.0ppm to trichlorfon, respectively. Furthermore, the values were high to p, p'-DDT and permethrin.
