Abstract:
Recent collections of Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) from California desert regions represent a mixture of biotypes. One biotype was identical to a culture originally obtained in 1981 and since maintained in the laboratory. The other and most prevalent biotype could not be distinguished morphologically but could be distinguished by esterase isozyme banding patterns. The banding patterns of the biotypes were not affected by culturing the whiteflies on different plant species. Different developmental stages, and adults of both sexes, had the same isozyme patterns. © 1992 Springer Science + Business Media B.V.
