Abstract：Objective To investigate the population composition,seasonal fluctuation of vectors(rodents,mosquitoes,flies,cockroaches)at a railway station in Chengdu,so as to provide a reference basis for vector control in large-scale transportation hubs.Methods Rodents,mosquitoes,flies and cockroaches were monitored by night trapping,light trapping,cage trapping and sticky trapping methods,respectively.Results The capture rate of rodents was 1.92%,and the dominant species was Rattus norvegicus.The average density of mosquitoes was 1.77 female mosquitoes/(light·night),and the dominant species was Culex pipiens quinquefasciatus.The average density of files was 43.08 files per cage.The top three fly species captured in number were 685 Chrysomyia megacephala,accounting for 33.12%,578 Lucilia sericata,accounting for 27.95%,and 403 Muscina stabulans,accounting for 19.49%.The average density of cockroaches was 1.67 cockroaches/sheet,the sticky trapping rate was 9.44%,and the dominant species was Blattella germanica.Conclusions Railway stations are high-risk areas for vector-borne diseases.Targeted measures should be taken based on the population distribution of vectors to enhance prevention and control,and reduce risks to human health.
