中文摘要：
目的】 调查西藏自治区烟粉虱Bemisia tabaci (Gennadius)的发生情况。【方法】 从西藏拉萨采集到烟粉虱各个虫态，采用3D数码显微镜观察所采集烟粉虱的形态特征，利用mtCOⅠ分子标记检测烟粉虱的生物型。【结果】 明确并详细描述了烟粉虱各形态特征，mtCOⅠ分子标记检测显示西藏采集到的烟粉虱为Q生物型。【结论】 在形态学鉴定的基础上，分子生物学鉴定该粉虱为Q型烟粉虱，这是Q型烟粉虱在西藏自治区发生的首次报道。
英文摘要：
[Objectives] To determine the biotypes of Bemisia tabaci (Gennadius) found in the Tibet Autonomous Region, China. [Methods] Morphological characteristics of whiteflies were observed under a 3D digital microscope, and the biotype of whiteflies collected from Lhasa, Tibet, identified on the basis of variation in the molecular marker mtCO. [Results] Analysis of variation in the mtCOImolecular marker shows that whiteflies collected in Tibet were of the Q biotype. [Conclusion] The results of both morphological identification and molecular analysis show that the whiteflies collected in Lhasa, Tibet Autonomous Region, were of the Bemisia tabaci Q biotype. This is the first report of the Bemisia tabaci Q biotype from the Tibet Autonomous Region.
