记述了茶树上一新记录粉虱——粉背刺粉虱Aleurocanthus inceratus Silvestri,该种亚缘区有11对长度一致的刺毛,其中头胸部5对;在背面中区头胸部有刺毛9对;腹部背面中区有14对,纵向分列3排;管状孔近圆形,盖瓣心形,尾沟不明显。统计了茶树上的9种粉虱即山茶褶粉虱Aleurotrachelus camelliae (Kuwana)、杨梅类伯粉虱Parabamisia myricae (Kuwana)、黑刺粉虱Aleurocanthus spiniferus (Quaintance)、番石榴白棒粉虱Aleuroclava psidii Singh、流苏子瘤粉虱Aleuroclava thysanospermi (Takahashi)、归亚瘤棒粉虱Aleuroclava guyavae (Takahashi)、杜鹃穴粉虱Aleurolobus rhododendri Takahashi、柑橘裸粉虱Dialeurodes citri (Ashmead)和粉背刺粉虱Aleurocanthus inceratus Silvestri,根据其伪蛹特征编制了茶树上粉虱分类检索表。
Aleurocanthus inceratus Silvestri, a newly recorded species of whitefly infesting tea plants, was morphologically described and illustrated. It has 11 pairs of spines along submarginal area, among which 5 pairs are on cephalothorax. Moreover, there are 9 pairs of spines on cephalothorax of the median dorsum, 14 pairs of spines on the median of venter, with 3 rows. Vasiform orifice and operculum are rounded.and cordate respectively., While caudal furrow is indistinct. Nine species of whitefly infesting tea plants in China were counted, namely, Aleurotrachelus camelliae (Kuwana), Parabamisia myricae (Kuwana), Aleurocanthus spiniferus (Quaintance), Aleuroclava guyavae (Takahashi), Aleurolobus rhododendri Takahashi, Dialeurodes citri (Ashmead), Aleurocanthus inceratus Silvestri. An identification key to identify these species based on the puparial characters was provided.
