Objective To analyze the species composition, distribution, density, and seasonality of mosquitoes in four counties (cities) of the Yellow River irrigation area of Ningxia Hui autonomous region (Ningxia), China, in 2019, and to provide a scientific basis for the prevention and control of mosquitoes and mosquito-borne diseases. Methods The light trapping method was used to carry out mosquito vector monitoring in the urban residential areas, rural houses, livestock sheds, and other habitats of Helan county, Pingluo county, Qingtongxia city, and Zhongning county in the Yellow River irrigation area twice a month during June to September in 2019. Excel 2007 software was used to establish a database, and SPSS 23.0 software was used for statistical analysis of data. The mosquito composition ratio was compared by the chi-square test, and the mosquito density was compared by analysis of variance. Results A total of 34 670 adult mosquitoes were caught from June to September 2019, with an average density of 46.10 mosquitoes/light-trap·night; there was no significant difference in mosquito density between different areas (F=2.357, P=0.930); Helan county had the highest average mosquito density, which was 252.96 mosquitoes/light-trap night. There was a significant difference in the composition of mosquito species between different areas (χ2=3 826.933, P<0.001); the majority of the mosquitoes caught belonged to Culex pipiens pallens and Cx. tritaeniorhynchus, accounting for 55.90% and 43.86%, of the total number of catches, respectively. Among the different habitats, livestock sheds had the highest density of mosquitoes, which was 73.55 mosquitoes/light-tarp·night, and there was a significant difference in the density of mosquitoes between different habitats (F=433.600, P <0.001). The seasonal fluctuation curve of mosquito density showed an obvious single-peak curve, and the difference of mosquito density in different months was statistically significant (F=938.159, P<0.001). Conclusion The mosquito density in the Yellow River irrigation area is generally at a relatively high level. Cx. pipiens pallens and Cx. tritaeniorhynchus are the dominant mosquito species in the area, and livestock sheds and rural houses are the places with a high incidence of mosquito infestation.
