“…Furthermore, the near-complete genomes of six mosquito-borne viruses were found, including Yongsan picorna-like virus 3, Culex Bunyavirus 1, Culex pipiens associated Tunisia virus, Wuhan Mosquito Virus 8, Hubei mosquito virus 4, and Wutai mosquito phasivirus. These viruses showed high identity with viruses reported in a metagenomic study from China, indicating that they do not exhibit strict geographical or mosquito species restrictions [ 33 , 46 ]. These viruses can potentially affect the transmission of viruses that are pathogenic to vertebrates, thus representing a potential tool for vector control strategies.…”

Background Mosquitoes host and transmit numerous arthropod-borne viruses (arboviruses) that cause disease in both humans and animals. Effective surveillance of virome profiles in mosquitoes is vital to the prevention and control of mosquito-borne diseases in northwestern China, where epidemics occur frequently. Methods Mosquitoes were collected in the Shaanxi-Gansu-Ningxia region (Shaanxi Province, Gansu Province, and Ningxia Hui Autonomous Region) of China from June to August 2019. Morphological methods were used for taxonomic identification of mosquito species. High-throughput sequencing and metagenomic analysis were used to characterize mosquito viromes. Results A total of 22,959 mosquitoes were collected, including Culex pipiens (45.7%), Culex tritaeniorhynchus (40.6%), Anopheles sinensis (8.4%), Aedes (5.2%), and Armigeres subalbatus (0.1%). In total, 3,014,183 (0.95% of clean reads) viral sequences were identified and assigned to 116 viral species (including pathogens such as Japanese encephalitis virus and Getah virus) in 31 viral families, including Flaviviridae, Togaviridae, Phasmaviridae, Phenuiviridae, and some unclassified viruses. Mosquitoes collected in July (86 species in 26 families) showed greater viral diversity than those from June and August. Culex pipiens (69 species in 25 families) and Culex tritaeniorhynchus (73 species in 24 families) carried more viral species than Anopheles sinensis (50 species in 19 families) or Aedes (38 species in 20 families) mosquitoes. Conclusion Viral diversity and abundance were affected by mosquito species and collection time. The present study elucidates the virome compositions of various mosquito species in northwestern China, improving the understanding of virus transmission dynamics for comparison with those of disease outbreaks.

“…All of the Rhabdoviridae -like viral contigs displayed hits to one reference RNA virus, Guampa vesiculovirus ( MN225577.1 ) ( Table S2 ). Guampa vesiculovirus was previously found in mosquitoes from the Brazilian Pantanal that are known to be critical vectors for transmitting animal diseases ( 31 ). Given that Rhabdoviridae is one of the most diverse RNA viral families characterized in other habitats ( 32 ), the finding of only 1 type of Rhabdoviridae in our samples suggests that the detected member could be relatively more adapted to permafrost thaw conditions.…”

“…Arboviruses represent a hot-topic as well. Maia et al [12] present the discovery of novel viruses in mosquitoes from Brazilian wetlands, including viruses from nine different families: Iflaviridae, Phenuiviridae, Rhabdoviridae, Flaviviridae, Reoviridae, Chuviridae, Circoviridae, Partitiviridae,and Totiviridae. The natural coinfection of Aedes aegypti by chikungunya and dengue type 2 virus in Brazil is also reported by Aragão et al [13] The influence of the environment on chikungunya virus transmission in Senegal is revealed by Sow et al [14].…”
