Abstract

Whiteflies (superfamily Aleyrodoidea) contain eubacterial endosymbionts localized within host cells known as mycetocytes. Sequence analysis of the genes for the 16S rRNA of the endosymbionts ofBemisia tabaci, Siphoninus phillyreae, andTrialeurodes vaporariorum indicates that these organisms are closely related and constitute a distinct lineage within the γ-subdivision of theProteobacteria. The endosymbionts of whiteflies are unrelated to the endosymbionts of aphids and mealybugs, which are in two separate lineages.
