【摘要】 [目的]明确西昌地区主要粉虱种类及寄主植物，为有效预防粉虱的传播蔓延提供理论依据。[方法]对西昌地区主要粉虱种类及其寄主进行调查采集，通过制作永久玻片，观察测量粉虱伪蛹的典型特征，根据其形态学特征鉴定粉虱种类。[结果]在西昌地区14科22种植物上分离鉴定出6种粉虱，即黑刺粉虱Aleurocanthus spiniferus、棒粉虱属未鉴定粉虱Aleuroclava sp.、烟粉虱Bemisia tabaci、孟加拉皮粉虱Pealius bengalensis、灰粉虱Siphoninus phillyreae、温室白粉虱Trialeurodes vaporariorum,其中烟粉虱为害作物占比最多、分布最广泛，是西昌地区为害最严重的粉虱种类。[结论]西昌地区14科22种植物上有6属6种粉虱，其中烟粉虱为优势种。更多还原

【Abstract】 [Objective]To clarify the main whitefly species and their host plants in Xichang area, and provide a theoretical basis for effectively preventing them from spreading.[Methods]The main whitefly species and their hosts in Xichang area were investigated and collected.In the laboratory, permanent glass slides were made.Based on the typical features of the whitefly puparium and the other important morphological features, the whitefly species were classified and identified.[Results]The results show that there are 6 whitefly species, Aleurocanthus spiniferus, Aleuroclava sp.,Bemisia tabaci, Pealius bengalensis, Siphoninus phillyreae and Trialeurodes vaporariorum on 22 plants in 14 families in Xichang area, of which Bemisia tabaci accounts for the largest proportion, and it is the most widely distributed and the most harmful whitefly species in Xichang area.[Conclusion]There are 6 whitefly species on 22 plants in 14 families in Xichang area and their redescriptions are provided.B.tabaci is widely distributed in Xichang area.更多还原
