We collected the unknown species of whiteflies throughout the Chungnam districts. Crepidiastrum sonchifolium (Bunge) Park & Kawano, Korean youngia was major plant to Cabbage whitefly and discovered throughout the Chungnam province in 2013. The unknown other species was collected on leaf of Morus alba L.(White mulberry) in September, 2014. We are attributing this species to Parabemisia sp.
It has been known that plants affected by Aleyrodes proletella Linnaeus, cabbage whitefly are leafy brassicas, including kale cabbage, broccoli and Brussels sprout and a minor pest of cabbage, bruseels sprouts and broccoli in Europe, being seldom a pest of agriculture but often troublesome to home gardeners. In cage of pupal, lingular head is simple, dorsal submargin without row of papillae and body not boxshaped. The pupal shape of Parabemisia sp.(attributted) is as follows. The fourth nymphal skin has 30 to 32 marginal setae including the caudal setae. The anterior spiracular furrows are scarecely visible, but the caudal furrow is slightly ridged longitudinally. The vasiform orifice is elongate triangular with the lingula included. The lingula has two blunt lateral tubercles and two long caudal lingular setae. The operculum covers only the anterior one-third of the vasiform orifice. In vivo, the nymphs are surrownded by a marginal fringe of clear wax.
