烟粉虱是许多农作物中最具威胁性的害虫之一。我们对采自印度尼西亚、泰国、印度和中国的50个烟粉虱种群的线粒体细胞色素氧化酶I基因进行了部分序列测定。在这些群体中鉴定出19个独特的细胞色素氧化酶I序列(单倍型)。将它们与数据库中的序列相结合，得到了总共407个单倍型，并与9个外群材料一起进行了分析。用最大似然法计算系统发育树。这棵树表明，在之前的研究中发现的所有群体也出现在我们的研究中。此外，根据新的单倍型确定了七个新的类群。大多数烟粉虱单倍型根据它们的地理起源进行分组。有两个群体被发现在全球范围内分布。我们的结果表明，我们对烟粉虱周围物种复合体的了解还远远不完整。
Bemisia tabaci is one of the most threatening pests in many crops. We sequenced part of the mitochondrial cytochrome oxidase I gene from fifty whitefly populations collected in Indonesia, Thailand, India and China. Nineteen unique sequences (haplotypes) of the cytochrome oxidase I were identified in these populations. They were combined with sequences available in databases, resulting in a total of 407 haplotypes and analyzed together with nine outgroup accessions. A phylogenetic tree was calculated using the maximum likelihood method. The tree showed that all groups that were found in previous studies were also present in our study. Additionally, seven new groups were identified based on the new haplotypes. Most B. tabaci haplotypes grouped based on their geographical origin. Two groups were found to have a worldwide distribution. Our results indicate that our knowledge on the species complex around B. tabaci is still far from complete.
