中文摘要: 运用扫描电子显微镜对烟粉虱Bemisia tabaci、非洲伯粉虱Bemisia afer、温室粉虱Trialeurodes vaporariorum和柑桔粉虱Dialeurodes citri 4种粉虱4龄若虫的超微形态特征进行了初步研究。结果表明,扫描电子显微镜下的超微结构特征可很好地将4种粉虱区分开来,如烟粉虱圆锥状的舌状突,非洲伯粉虱尾沟两侧隆起上形成的横脊,温室粉虱形态典型的乳突和泌蜡孔,柑桔粉虱近圆形的皿状孔及其尾沟内的卵石状乳突等特异特征。并根据种间的超微结构特异特征,编制了不同种的简明检索表。超微形态特征为粉虱种群鉴定提供了可靠的理论参考。
英文摘要: The ultra-morphological characteristics of the 4th instar nymphs of four whitefly species,including Bemisia tabaci,Bemisia afer,Trialeurodes vaporariorum and Dialeurodes citri,was observed with scanning electron microscope(SEM). The results showed that the ultra-morphological characteristics could be make a distinction among four whitefly species researched,such as the conical lingula of Bemisia tabaci,the horizontal wrinkles on bulge region beside the end groove of Bemisia afer,the protuberance and aperture uesd to screte wax of Trialeurodes vaporariorum,the circular vasiform orifice and pebble protrude in the end groove of Dialeurodes citri,et al. And on the basis of the peculiar ultra-morphological characteristics among species of whitefly researched,draw up a concise program to retrieval. The ultra-morphological characteristics provided dependable reference to taxonomy for whitefly.
