摘　　要：目的了解景德镇市不同生境三带喙库蚊密度水平及其季节消长变化,为后续研究提供数据支持。方法于2010-2014年采用诱蚊灯法对景德镇市居民区、公园、医院、农户和牲畜棚5种生境的蚊类进行监测,每月2次;利用SPSS 19.0软件处理数据,采用LSD-t及SNK-q检验对不同年度、不同生境中的三带喙库蚊数量进行统计学分析。结果 2010-2014年景德镇市以三带喙库蚊为优势蚊种,占捕蚊总数的51.26%。其蚊虫总数呈逐年下降趋势,差异有统计学意义(y=-749.1x+1 509 397.4,R^2=0.917,P=0.010)。三带喙库蚊密度分布呈单峰型,最高峰在6月,密度为3.28只/(灯·夜)。牲畜棚和农户的三带喙库蚊数量远高于其他生境,但呈明显下降趋势,不同生境蚊虫数量最高峰均在6月,但农户在8月还有1个小高峰。结论初步掌握了景德镇市三带喙库蚊密度水平、生境差异、年度波动和季节消长等情况,为后续工作提供了基础数据。Objective To acquire the density and seasonal fluctuation information of Culex tritaeniorhynchus inJingdezhen city, and provide data for following study. Methods Light traps were used to get surveillance data fromresidential areas, parks, hospitals, farmyards and livestock sheds in Jingdezhen city twice per month between 2010 and2014. LSD-t and SNK-q were used to analyze the data by SPSS 19.0. Results Culex tritaeniorhynchus was thepredominant mosquito specie in Jingdezhen, accounting for 51.26% of the mosquito population. The declining trend in 2010 to 2014 was significant（y=-749.1 x＋1 509 397.4, R^2=0.917, P=0.010）. The temporal distribution of Cx. tritaeniorhynchus showed a single peak in June, which the density was 3.28 per light per night. Although the density in livestock sheds andfarmyards was much higher than other habitats, the declining trend kept the same. The maximum peak in June appeared inall habitats while the farmyard had a secondary peak in August. Conclusion In this study, we acquired the density,habitat, interannually fluctuation and seasonal variation of Cx. tritaeniorhynchus in Jingdezhen city, and provided the basicdata for the follow-up work.
