Abstract :The aim of the study to determine the morphological features of Parabemisia myricae insert ignore into journalissuearticles values(Kuwana); and morphological comparisons with Dialeurodes citri insert ignore into journalissuearticles values(Ashmead); and Bemisia tabaci insert ignore into journalissuearticles values(Genn.);. Eggs of P.myricae are in ellipsoidal shape with a short stem which is attacked to the leaf surface. The eggs are yellowish-white in color when they have just laid, and become black in color, 1-2 days later. It has 3 nymph stages, prepupa and pupae before becomes adult. The shape of nymph and pupae stages are resemble to scale insects and in addition they have waxy plates around the body. In nymph stages its greenish yellow color turns to fully yellow in the pupae stage. The body generally convex in shape with a clear red eye marks in pupae stage in contrast nymph stage which has not eye marks Adults 3 pair of legs and 2 pair of wings. The appearance of adults are white, because of the body covered with powdery waxy excretion. In morphological point of view P.myricae resemble to D.citri and B.tabaci However, they are some differentiation among the whitefly species, firstly the eggs of P.myricae become black in color by the development; secondly, there are waxy plates around the nymph and pupae; thirdly, the size of the body of all development stages varies by the whitefly species. In addition to these differentiation, the species can be discriminated by the shape of vasiform orifice in microscopic examination.
