Abstract EN
Aedes albopictus is a very important vector for pathogens of many infectious diseases including dengue fever.
In this study, we explored the genetic polymorphism of Aedes albopictus strains in different geographical regions using DNA barcoding of mitochondrial COI (MT-COI) gene.
We collected MT-COI sequence of 106 Aedes albopictus mosquitos from 6 provinces in China including Fujian, Guangdong, Hainan, Yunnan, and Taiwan.
The length of the sequences is 709bp with the content of A+T (67.7%) greater than that of G+C (32.3%).
We identified mutations in 90 (13.68%) loci, of which 57 (63.33%) are transitions, 28 (31.11%) are transversions, and 5 (5.56%) are hypervariable loci.
In addition, we obtained 42 haplotypes, 4 (9.52%) of which are shared among different populations.
The haplotype diversity of Aedes albopictus is 0.882 and nucleotide diversity is 0.01017.
Moreover, the pedigree network diagram shows that most haplotypes are under parallel evolution, suggesting a local expansion of Aedes albopictus in history.
Finally, the Neighbor-Joining tree of MT-COI haplotypes reveals a certain correlation between haplotype clusters and geographical distribution, and there are differences among Aedes albopictus in different geographical regions.
In conclusion, DNA barcoding of MT-COI gene is an effective method to study the genetic structure of Aedes albopictus.
