摘要 目的调查研究淡色库蚊在山东省潍坊市的越冬情况。方法分别在2014年10月至2016年3月通过人工调查法对潍坊地区越冬蚊进行调查,并监测了整个越冬期内淡色库蚊的种群动态。结果淡色库蚊在潍坊地区以雌成蚊越冬,越冬场所种类多,其中密度较高的越冬场所主要有地窖(135.5±8.75)、防空洞(113±9.56)、暖气管道(33.2±3.84)等,不同越冬场所内淡色库蚊越冬蚊密度存在显著差异(F=85.72,df=139,P<0.01)。越冬期内,各调查点淡色库蚊阳性率大致呈先增加后降低的趋势,捕获的蚊虫数量在越冬中期最多,其次为越冬前期,越冬后期捕获数量最少。结论本研究阐明了山东省潍坊市淡色库蚊的越冬场所和越冬种群的动态,为淡色库蚊的预测、预报和综合防治提供了理论依据。 Objective To clarify the population dynamics and winter habitats of Culex pipiens pallens in Weifang City of Shandong Province.Methods The population dynamics and winter habitats of Cx.pipiens pallens were monitored using aspirators,and numbers were converted to density collected per man-hour from early October of 2014 to March of 2016.Results Female adult of Cx.pipiens pallens overwintered in diversified habitats.The highest densities occured in cellars,followed by air-raid shelters and heating pipelines,the average density of Cx.pipiens pallens per man-hour were 135.5,113 and 33.2 respectively.The adult densities at six sites(including cellars,air-raid shelters,heating pipelines,sewers,mountain caves and wells) showed significant differences(F=85.72,df=139,P< 0.01).During the winter,the positive rate of Cx.pipiens pallens increased first and then decreased.The mosquitoes were captured mostly in the middle of overwintering,followed by the early overwintering and the lowest in the late overwintering.Conclusion This study describes the winter habitats of Cx.pipiens pallens and the population dynamics in Weifang City of Shandong Province,and provides a basis for the prediction and control of Cx.pipiens pallens.
