Abstract：Objective To investigate the density,species composition and seasonal fluctuation of the important vectors in Baise,so as to provide a basis for formulating scientific and rational plans of vector control.Methods From 2022 to 2024,rodents,mosquitoes,flies and cockroaches were monitored by the night cage method,light trap method,cage trapping method and sticky-trap method in Baise,respectively.Excel 2021 and SPSS 27.0 software were used for statistical analysis of the data.The densities of vectors in different habitats were compared using analysis of variance(ANOVA).If the data did not meet the assumptions of normality or homogeneity of variances,the Kruskal-Wallis H test was used instead.Results From 2022 to 2024,the annual average densities of rodents were 5.40%,7.06%,and 5.78%,respectively,with Rattus norvegicus accounting for 73.70%and being the dominant species.The seasonal fluctuation showed a bimodal curve,with the peak periods were in March and November.Rodents were mainly distributed in key industries.The annual average densities of mosquitoes were 21.19,27.07 and 9.69 mosquitoes/(lamp·night),respectively.Culex quinquefasciatus was the dominant species(55.82%),and the density peak was in June.The density of mosquitoes in the livestock sheds was the highest.The annual average densities of flies were 1.65,1.18,and 0.48 flies per trap,respectively,with the dominant species being the Musca sorbens(37.27%).And there was no obvious peak period throughout the year,with the highest density habitat being the farmers'market.The annual average densities of cockroaches were 0.63,0.27,and 0.21 cockroaches per sheet,respectively,with infestation rates of 8.45%,3.97%,and 3.62%,respectively,and Blattella germanica(86.62%)was dominant species.Cockroaches were mainly distributed in farmers' market and catering,and two small peaks of density were in March and July.Conclusion In Baise,the dominant species of vectors are R.norvegicus,Cx.quinquefasciatus,M.sorbens,and B.germanica.The peak density periods for different types of vectors vary.Control measures can be implemented based on surveillance results and actual conditions.
