Technical Abstract: The sweetpotato whitefly, Bemisia tabaci (Gennadius), (Homoptera: Aleyrodidae), is an important pest in many cropping systems throughout the world. Currently two biotypes of this species are present in Florida, the B-biotype discovered in Florida in 1986 and the recently introduced Q-biotype. B-biotype has been successfully managed with neonicotinoid insecticides, especially imidacloprid. However, with the introduction of Q-biotype, which has characteristically shown resistance to a number of neonicotinoids, it is feared that effective management of B. tabaci will be compromised. Therefore, knowing the susceptibility to insecticides of Q-biotype in Florida would be valuable in developing management strategies. The objective of this study was to determine the toxicity of imidacloprid, dinotefuran, pyridaben, and cyfluthrin to a strain of Q-biotype collected from Florida.
