We evaluated the effects of seven granular insecticides on the population density of Thrips nigropilosus Uzel occurred on chrysanthemum cultivated in a greenhouse. In our study, acephate, carbosulfan(organophosphate), benfuracarb(carbamate), acetamiprid, clothianidin, imidacloprid, and nitenpyram(neonicotinoid) were applied to the soil at the recommended dose(0.3 g, 1.0 g, or 2.0 g / plant) immediately after planting. The number of the thrips on chrysanthemum was investigated on 0, 6, 13, 20, 27, 33, and 41 days after applications. Our results indicated that all the seven insecticides were effective against T. nigropilosus though efficacy and its duration were significantly different among insecticides. Benfuracarb was shown to be the most effective insecticide for suppressing the density of the thrips.
