This study investigated the effects of insecticides on the first instar larval and adult stages of the melon thrips, Thrips palmi Karny (Thysanoptera: Thripidae) using two bioassay methods, leaf spraying and leaf dipping. The corrected mortality rates of the larval and adult stages for three insecticides (emamectin benzoate, abamectin, and pyridalyl) were 90%–100% in both methods. The corrected mortality rates of the larvae for most insecticides tended to be higher than those of the adults, except for two insecticides (emamectin benzoate and flonicamid).
