Characterization of Bemisia tabaci populations
A report on the biotic characterization of Bemisia tabaci (EPPO A2 pest) populations based on esterase profiles, DNA fingerprinting, virus transmission and bioassay to key host plants was presented at the 1992 Annual Meeting of the American Phytopathological Society. Twenty populations of B. tabaci from North and Central America, the Caribbean basin, West and North Africa, the Middle East and Asia were thus characterized. Populations from Arizona (US), California (US), Florida(US), Puerto Rico, Antigua and Yemen had identical esterase and DNA profiles, vectored the ten candidate geminiviruses with high efficiency and induced phytotoxic disorders in the indicator plants. The authors concluded that these six populations of B. tabaci are genetically homogeneous and that a biologically and genetically identical biotype is present in several world regions.
