Abstract： Aiming at the problems of large population and serious harm of Bemisia tabaci in the field under vegetable-tobacco rotation planting mode in Yanbian region of Panzhihua， field investigation and plot experiment were conducted，and the main biotype of the B .tabaciin the vegetable-tobacco rotation area of Yanbian region of Panzhihua was determined to be B type. Control effect of foliar spray of different chemical agents on B . tabaci and occurrence of tobacco mosaic virus disease were evaluated. The effective combinations of chemical agents for the control of B . tabaci in vegetable-tobacco rotation field were selected，among which，the combination of 5% lufenuron cream and 20% dinotefuran suspension diluted to 4Oo times had the best control effect on B . tabaci.Control effect reached to 57.59% on B . tabaci and 42.37% on tobacco mosaic virus disease at lO days after the second treatment. Moreover，the combination also showed a significant growth promoting effect on tobacco plant height， stem circumference and maximum leaf area of the plants at 7 days after topping. This study provided a material support for the healthy cultivation of tobacco in Panzhihua.
