Abstract:Objective To investigate the distribution of mosquito species and mosquito-borne viruses in some regions of Hebei Province, and to provide a basis for prevention and control of mosquito-borne diseases in these regions. Methods Mosquitoes were collected by lamp trapping method in nature. Mosquito samples were classified according to morphologic characteristics and then stored at liquid nitrogen. Viruses were isolated in cell culture and characterized using molecular biological methods. Biological information software was used to analyze the molecular biological characteristics of viral nucleotide sequences. Results A total of 2,638 mosquitoes (4 species, 3 genera) were trapped in Pingshan County, Wei County and Pingxiang County of Hebei Province in September 2019. The dominant species was Culex pipiens (69.6%, 1,835/2,638), followed byArmigeres subalbatus (20.5%, 541/2,638). A virus strain isolated from a mosquito sample (PX54) from Youzhao Town of Pingxiang County was identified as Culex pipiens pallens densovirus. Conclusion The predominated species of mosquitoes trapped in the surveyed regions of Hebei Province are different. Wei County and Pingxiang County are dominated by Culex pipiens, but Pingshan County is dominated by Armigeres subalbatus. Moreover, one strain of densovirus is isolated from Culex pipiens in Youzhao Town of Pingxiang County.
