Abstract
8 insecticides were studied on the toxicities to Bemisia tabaci adults using vivo bioassay method,in order to choose the better insecticides and guide insecticides mixed.The results showed that high mortalities were showed by Avermectins and spinosad,their LC50 were 0.04 and 0.13 μg/mL,respectively.The LC50 of imidacloprid and fipronil were 1.15 and 8.31 μg/mL,and they showed better quick-acting.Avermectins,imidacloprid,fipronil and spinosad might be the best choices for Bemisia tabaci adults control in the field in Guangzhou area.
