The mtDNA C0I gene sequences were utilized to identify biotypes and established phylogenetic relationships of Bemisia tabaci from Hefei. The results showed that it was belonged to Q-biotype and the genetic similarities with the population from Kunming reached 99. 8% -100% . It was concluded that the population of B. tabaci from Hefei is probably the invasive alien insect and has the same origin with the population from Kunming.%利用mtDNA COI基因片段对安徽合肥地区烟粉虱生物型进行了鉴定及系统发育分析.结果表明,合肥地区所采集烟粉虱为Q型,且与云南昆明地区的烟粉虱种群同源性达到99.8％ ～ 100％,推测安徽合肥地区Q型烟粉虱很可能为外来入侵害虫,其发源地应该与云南昆明地区Q型烟粉虱一致.
