Some whitefly species that infest floriculture and nursery crops. These can be distinguished by pupal shape and filaments, adult wing markings, and the waxiness associated with their colonies. Note that the appearance of silverleaf whitefly (<i>Bemisia argentifolii</i>, or <i>Bemisia tabaci</i> B biotype) cannot be distinguished from sweetpotato whitely (<i>Bemisia tabaci</i> Q biotype).
