Abstract：Objective To clarify the characteristics of mosquito community structure and environmental heterogeneity in Binzhou,so as to provide basis for precision control of mosquito-borne diseases.Methods From 2021 to 2023,ecological monitoring of adult mosquitoes was conducted in urban residential areas,parks(including neighborhood parks),hospitals,farmers'households,cattle sheds,pigsties,and breeding farms in seven counties(districts)of Binzhou using light trap methods.One-way ANOVA and the Kruskal-Wallis H test were employed to analyze differences in average mosquito density among different habitats and different years.Results A total of 4 genera and 5 species of mosquitoes were collected,and Culex pipiens pallens was the dominant species.From 2021 to 2023,the average mosquito densities of Cx.pipiens pallens were 10.47,9.37,and 8.87 mosquitoes per lamp,respectively.There was no statistically significant difference in the average density of mosquitoes between different years.There was a statistically significant difference in average mosquito density between different habitats(P＜0.05).The higher average mosquito densities were found in cattle sheds and breeding farms,which were 21.74 and 21.55 mosquitoes per lamp,respectively.The mosquito density showed obvious seasonal distribution,and the peak occurred from June to September.At the species level,Boxing presented significantly high biodiversity characteristics and should to be a key area for mosquito control.Conclusion From 2021 to 2023,the mosquito density in Binzhou was still at a high level.It is necessary to pay close attention to the change of mosquito vector density,and to formulate comprehensive control strategies.
