Abstract：Objective To understand the population composition,density,and seasonal fluctuation of main vectors in a military unit,so as to provide a scientific basis for vector control.Methods From early April to October 2023,the vectors in the camp area were investigated in accordance with the National Vector Biology Monitoring Implementation Plan.The double mosquito net method was used for adult mosquito,the night trapping method was used for rodent,and the manual flagging method and host tick inspection method were used for tick.Results The mosquitoes included 7 species belonging to 1 family,2 genera and 4 subgenera,including Ochlerotatus caspius,O.dorsalis and Culex pipiens pallens.The dominant species was O.caspius,accounting for 60.64%.A total of 41 overwintering mosquitoes were captured in early April,all of which were Cx.pipiens pallens.The adult mosquito density in corridors was 4.33 mosquitoes per site,which was higher than that in other places.The average adult mosquito density in the stadium was 623.00 mosquitoes per tent per hour,which was higher than that in the hospital and the camp area.There was a significant positive correlation between mosquito density and temperature in all three habitats(all P＜0.05).The captured rodents were Rattus norvegicus and Mus musculus.R.norvegicus was the dominant rodent species,accounting for 94.10%of the total rodent population,while M.musculus accounted for 5.90%.Rodents were primarily distributed in livestock sheds and the camp area,with a higher density in livestock sheds.Few rodents were found in outdoor areas such as parks and the stadium.Dermacentor niveus was the dominant tick species,accounting for 85.50%of the total number of captured ticks.Twelve individuals of Hyalomma asiaticum were captured,accounting for 14.50%of the total number of captured ticks.Among them,10 were nymphs,accounting for 12.00%of the total number of captured ticks.Questing ticks were mainly distributed in the sewage treatment plant,whereas on-host ticks were primarily distributed in livestock sheds.Conclusion The main vectors in a military unit were O.caspius,R.norvegicus and D.niveus.Different control measures should be taken according to different vector species.
