In the laboratory bioassays, a two-year study was conducted to evaluate mortality of False Chinch Bug (FCB), Nysius raphanus (Howard) (Hemiptera: Lygaeidae), to selected insecticides. All treatments caused significantly FCB mortality in both years. In the first year, diazinon and chlorpyrifos were significantly more effective insecticides than other insecticides. A thiamethoxam and spinosad were the least effective insecticides. In the second year, permethrin, thiamethoxam, endosulfan and chlorpyrifos were the most effects insecticides for causing on FCB mortality at 24 h, while an esfenvalerate, lambda-cyhalothrin and imidacloprid were less effective insecticides.
