摘　　要：为了准确描述Q型烟粉虱Bemisia tabaci(Gennadias)各个龄期的形态特征,应用超景深显微镜(VHX-600)和扫描式电子显微镜(S-3400NII)对寄主植物黄瓜上Q型烟粉虱进行了详细的记录和观察。结果表明,烟粉虱的卵呈长梨形;1龄若虫边缘刚毛16对,可爬行;2龄若虫眼点明显,边缘呈圆齿状;3龄若虫体色变浅,胸气门、尾气门可见,眼点变红色;4龄若虫椭圆形,体黄色,皿状孔三角形,舌状突长匙状。成虫淡黄白色,翅2对,覆盖白色蜡粉,雌虫体长(0.91±0.04)mm,翅展(2.13±0.06)mm;雄虫略小。停息时左右翅合拢呈屋脊状,并稍分开,可见黄色的腹部。研究结果为Q型烟粉虱的鉴定提供了形态依据。In order to describe the morphological characteristics of Q Bemisia tabaci(Gennadias)of life stages,we observed and studied Q Bemisia tabaci on Cucumis sativus L.by using Microscope VHX-600 and SEM(S-3400NII).Eggs,nymphal body sizes and characters were measured and observed,including the vasiform orifice,operculum,lingula.Adult characters of both sexes were investigated including the body size,compound eyes,antennal segments.The results showed that the eggs were pyriform;the 1st instar nymph can crawl,16 pairs of marginal setae present;the 2nd instar nymph had obvious eye spots,and the margin rounded dentate;thoracic trachealfolds and caudal tracheal folds could be seen of the 3rd instar nymph,and the eye spots turned red;the 4th instar(pupal case)was oval,yellow,vasiform orifice was rounded-triangular and lingula was long spoon.The adult was light yellowish,2 pairs of wings hyaline,dusted with powdery wax.The length of the female is(0.91±0.04)mm and the wingspan is(2.13±0.06)mm.The male is slightly smaller.The left and right wings close to form a ridge,yellow abdomen was visible.The results provide a solid morphological basis for the identification of Q Bemisia tabaci.
