摘要
目的对山东省滕州市红荷湿地蚊虫种类、季节消长及病毒携带状况进行调查,以便更好地应对当地蚊媒防治工作。方法在红荷湿地不同观景区设置7个监测点,2022—2024年每年4—11月每月采用诱蚊灯法开展生态学监测,于2023年6—9月采用巢氏PCR法对3000只常型曼蚊进行黄病毒检测。结果2022—2024年,滕州市红荷湿地共布放诱蚊灯153台夜,捕获雌蚊20336只,平均蚊密度为132.92只/(灯·夜),经鉴定为6属19种,在中国内地鉴定到Lutzia chiangmaiensis蚊,在鲁南地区报道近黑按蚊、稻富库蚊和东乡伊蚊。优势蚊种为常型曼蚊15345只(75.46%),其次为三带喙库蚊1824只(8.97%)、黄色轲蚊1408只(6.92%)和中华按蚊1026只(5.05%)。不同蚊种季节变化趋势有差异性,6—9月为成蚊总体活动高峰期,黄色轲蚊、中华按蚊、常型曼蚊和三带喙库蚊活动高峰分别为6、6、7和8月;淡色库蚊密度始终较低,且于10月份才呈现上升趋势。3000只常型曼蚊病毒检测结果为阴性。结论滕州市红荷湿地蚊虫种类丰富,密度较高,提示5—9月有乙脑和疟疾等传播风险,应及时开展滕州红荷湿地蚊媒综合防制措施。
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 3000 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 20336 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 China'Mainland,and similarly for Anopheles pullu,Culex inatomii,and Aedes togoi in southern Shandong Province.The dominant species was Ma.uniformis(15345,75.46%),followed by Culex tritaeniorhynchus(1824,8.97%),Coquillettidia ochracea(1408,6.92%),and Anopheles sinensis(1026,5.05%).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 3000 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.
