Abstract:
The mosquito Aedes albopictus is the primary vector for dengue virus transmission in Fujian Province.Despite that active dengue surveillance has been launched in several sites since 2005,the genetic diversity of A.albopictus from these sites remains exclusive.In this study,mosquito pools collected from dengue surveillance sites during 2015-2016 were randomly selected,the full-length mitochondrial cytochrome C oxidase subunit Ⅰ (mtDNA-COⅠ) were amplified and sequenced.Preliminary sequence alignment of 12 amplicons with the reference sequence indicated 99 ％ homology at nucleotide level,due to varia tions at 9 nucleotide sites.Three haplotypes,namely H02,H03 and H08,were determined based on phylogenetic analysis with 72 reference sequences of known haplotypes.These observations facilitate surveillance and control of arboviral diseases in Fujian.
