Abstract:

Objective To investigate indoor mosquito species distribution in different geographical locations and ecological environments in Hubei province. Methods Mosquitoes were captured from May to September in 2014, species and sex composition were analyzed with statistical tests. Results Five species including Culex pipiens quinquefasciatus, Cx. tritaeniorhynchus, Armigeres subalbatus, Anopheles sinensis and Aedes albopictus were captured, accounted for 46.37%, 25.99%, 15.37%, 12.14% and 0.13%, respectively. From different topographologic types, Cx. pipiens quinquefasciatus and Cx. tritaeniorhynchus were predominant in plains, Cx. pipiens quinquefasciatus, Ar. subalbatus and Cx. tritaeniorhynchus were predominant in hilly areas. From different host types, Cx. tritaeniorhynchus and Ar. subalbatus were predominant in stables, Cx. pipiens quinquefasciatus was common in birdhouses and human dwellings. Females of 5 species were captured, but males from only two species were captured including Cx. pipiens quinquefasciatus and Ar. subalbatus. Conclusion Predominant species and sex composition show significant difference among different topographical environments and host types.

摘要：

目的 调查湖北省不同地理位置及生态环境室内蚊种分布情况。方法 2014年5-9月用栖息蚊虫捕捉法捕获不同地貌、生境的成蚊,并用统计检验方法分析所捕获蚊虫种类、雌雄性别及数量构成的差异。结果 湖北省室内蚊种总体构成比由高到低依次为致倦库蚊(46.37%)、三带喙库蚊(25.99%)、骚扰阿蚊(15.37%)、中华按蚊(12.14%)和白纹伊蚊(0.13%)。从地形地貌角度,平原优势蚊种为致倦库蚊、三带喙库蚊,丘陵优势蚊种为致倦库蚊、骚扰阿蚊和三带喙库蚊;从宿主类型角度,牲畜圈优势蚊种为三带喙库蚊和骚扰阿蚊,禽圈和人房优势蚊种为致倦库蚊。室内能采集到致倦库蚊、三带喙库蚊、骚扰阿蚊、中华按蚊和白纹伊蚊5种雌蚊,而雄蚊只有致倦库蚊和骚扰阿蚊2种。结论 不同地貌、生境和血源影响蚊虫分布,其优势蚊种、性别构成有显著差异。
