Effectiveness of control by the application of granular or wettable powder clothianidin against Liriomyza trifolii (Burgess) was evaluated in greenhouse tests on tomato plants. The control effect of granular clothianidin against L. trifolii was more effective than both nitenpyram and acephate. The larvae of leafminer did not occur on tomatoes for about 3 weeks after a granular application at planting. The application of clothianidin WP was more effective than acephate WP and flufenoxuron EC, and the mortality of middle-stage larvae by clothianidin WP was 36.6% and 54.2%. It was considered that clothianidin has the potential become to be one of the principal insecticides in tomato cultivation.
