烟粉虱Bemisia tabaci是一个至少包括36个不同隐种的物种复合体,为明确中国本地烟粉虱隐种的分布,采用线粒体COI基因(mt COI)分子标记法对2011—2012年在中国27个省(市)61个烟粉虱种群中获得的45个非B/Q隐种烟粉虱个体进行了隐种鉴定和分析,并利用邻接法基于mt COI序列构建了本地烟粉虱隐种的系统发育树。结果显示:45个非B/Q隐种烟粉虱对应的45条线粒体COI序列中共有10个单倍型,所有单倍型分别属于烟粉虱Asia II 2、Asia II 6、Asia II 7、Asia I与China1隐种,均为我国本地隐种。其中,在安徽省发现烟粉虱Asia II 2和China1隐种,在福建省发现Asia II 6和China1隐种,在海南省发现Asia II和Asia I隐种,在广东省发现Asia II 7隐种,在江西省发现China1隐种。表明中国部分农区作物上仍然存在少量的本地烟粉虱。
Bemisia tabaci (Bemisia tabaci) is a complex composed of at least 36 species with different hidden species. To identify the distribution of the invasive species of Bemisia tabaci in China, mitochondrial COI gene (mt COI) Forty-five non-B / Q offspring Bemisia tabaci (B. tabaci) individuals were identified and analyzed in 61 Bemisia tabaci populations from different provinces (cities). Based on the mt COI sequence, Phylogenetic tree. The results showed that there were 10 haplotypes in 45 mitochondrial COI sequences of 45 non-B / Q B. tabaci and all haplotypes belonged to B. tabaci Asia II 2, Asia II 6, Asia II 7, Asia I and China1 are hidden, all of which are hidden in our country. Among them, B. tabaci Asia II 2 and China 1 were found in Anhui Province, Asia II 6 and China 1 were found in Fujian Province, Asia II and Asia I in Hainan Province, and Asia II 7 in Guangdong Province , China1 hidden species found in Jiangxi Province. Indicating that there are still a few local whiteflies in some agricultural areas in China.
