Abstract： Scanning electron microspcopy was used to reveal the morphology and detailed ultra-structure of the antenna,stylet,and tarsal sensilla of three whiteflies;Bemisia tabaci,Trialeurodes vaporariorum,Alenrocybotns indice. All three species have microtrichia and 2 sensilla, i.e. chaetae sensilla and basiconic sensilla on the antennae.B. tabaci has 2 other types of sensilla on the antennae:campaniform sensilla and coebconic sensilla, but no campaniform sensilla were found on the on the antennae of T. vaporariorum and A. indice.All three species have similar morphological characteristics of microtrichia and chaetae sensilla on stylet, and tarus.
