COMPLETE GENOME OF AEDES ALBOPICTUS ANPHEVIRUS FROM PORT AREAS IN JIANGXI PROVINCE
Journal Title: Acta Parasitologica et Medica Entomologica Sinica - Year 2024, Vol 31, Issue 2
Abstract
[Objective] Insect-specific viruses (ISVs) in Aedes albopictus are closely associated with the transmission and replication of pathogenic infectious agents, such as dengue, chikungunya and Zika virus. In this study, their genome sequence was deciphered to provide a theoretical basis for developing of novel insect-borne virus control strategies. [Methods] Next-generation sequencing (NGS) technology was used to investigate ISVs in Ae. albopictus field populations collected from three port areas in Jiangxi Province (Nanchang Changbei Airport, Jiujiang Chengxi Port and Ganzhou Port). [Results] It turned out that the ISV Aedes albopictus anphevirus (AealbAV) was widely detected in the three field Ae. albopictus populations. Sequencing reads were assembled using MEGAHIT software and two strains of AealbAV were obtained that were highly homologous (>98%) to the virus strain, MW147277.1 (identified in the US). The GenBank numbers of the two strains were Jiujiang OR715784 and Ganzhou OR729834. In addition, we sequenced the Nanchang strain, but failed to obtain an assembled full-length genome. [Conclusion] AealbAV is prevalent in Ae. albopictus populations in Jiangxi, and its genomic research provides a theoretical basis for integrated control of Ae. albopictus using insect-specific viruses in port areas.
