Abstract
Objective To investigate the species composition,seasonal variation,and virus-carrying status of mosquitoes in the Honghe Wetland of Tengzhou City to better control local mosquito vectors.Methods Seven surveillance sites were established in different scenic spots of the wetland,and ecological monitoring was carried out monthly from April to November each year using the light-trapping method.From June to September 2023,a total of 3 000 Mansonia uniformis mosquitoes were tested for flaviviruses using the nested PCR method.Results From 2022 to 2024,a total of 153 mosquito trap lamp·nights were deployed in the Honghe Wetland,and 20 336 female mosquitoes were captured,with an average density of 132.92 mosquitoes/lamp·night.The mosquitoes were identified as belonging to 19 species across 6 genera.Among them,Lutzia chiangmaiensis was identified for the first time in mainland China,and similarly for Anopheles pullu,Culex inatomii,and Aedes togoi in southern Shandong Province.The dominant species was Ma.uniformis(15 345,75.46%),followed by Culex tritaeniorhynchus(1824,8.97%),Coquillettidia ochracea(1408,6.92%),and Anopheles sinensis(1 026,5.05%).The peak period of adult mosquito activity was from June to September.The seasonal variations in the density of the different mosquito species differed,with the peak periods of Cq.ochracea,An.sinensis,Ma.uniformis,and Cx.tritaeniorhynchus being in June,June,July,and August,respectively.The density of Cx.pipiens pallens was consistently low,showing an upward trend in October only.The 3 000 Ma.uniformis mosquitoes were negative for the three viruses tested.Conclusions The mosquitoes in the Honghe Wetland of Tengzhou City are rich in species composition and high in density.Because of a possible risk of transmission of Japanese encephalitis and malaria in the period between May and September,comprehensive mosquito control measures need to be strengthened in the Honghe Wetland of Tengzhou City.关键词
