The toxicity of fourteen insecticides on melon thrips, Thripspalmi Karny, collected from cucumber or eggplant in four regions of Osaka Prefecture was examined using a broad bean leaf dipping method. The corrected mortality rate was high with emamectin benzoate and medium or low with the other insecticides. The results indicate that only emamectin benzoate is highly effective in controlling the four regional populations.
