Abstract:

Objective To investigate the species composition and distribution of mosquitoes, as well as the arbovirus harborage status in Xinjiang Uigur Autonomous Region, China. Methods Mosquito samples were collected via ultraviolet (UV) light traps and net. After being identified, the samples were preserved in liquid nitrogen. The virus carried by the samples was detected through molecular biological methods. Results A total of 3 550 mosquitoes were collected, which cover 7 species in 4 genera. In the aspect of species, Culex pipiens Linnaeus consists the largest part among the samples, which accounts for 54.28%. Followed the Cx. pipiens is Aedes caspius, accounting for 29.38%. Remaining 5 species accounted for 16.34%. The results of the molecular biological examination showed that following 8 virus are negative among our samples, which are genera of flavivirus, alphavirus, Bunia virus and Japanese encephalitis virus, Liaoning virus, Tahyna virus, tick-borne encephalitis, and West Nile virus. Conclusion The study demonstrates a general landscape of the species composition and distribution of mosquitoes in Xinjiang Uigur Autonomous Region. Although the result of the molecular biological examination were negative, it should not be ignored the risk of arbovirus infection, further and more developed researches are still required in this aspect.
