1997-2007年三峡库区监测点蚊类监测资料分析

Analysis on the data of the mosquitoes monitoring from 1997-2007 in Three Gorges Reservoir area

目的了解三峡库区蚊类种群构成及密度的动态变化和季节消长规律。方法在固定的地点和时间,利用直流电动捕蚊器捕捉蚊虫,然后分种统计捕获的蚊虫数。结果三峡库区的优势蚊种为骚扰阿蚊、致倦库蚊、淡色库蚊、中华按蚊和三带喙库蚊。人房成蚊密度均低于畜圈。优势蚊种的季节分布呈单峰型,总体上最高峰在6-7月出现。结论1997-2007年三峡库区成蚊密度总体呈现下降趋势,应继续加强监测工作。

Objective Know the dynamic change of mosquito population constitution and its density and its seasonal fluctuation in Three Gorges Reservoir area. Methods The mosquitoes were captured by direct current electric mosquito-catching trap at the fixed time and places, and then identified and counted. Results The dominant species of mosquitoes were Armigeres subalbatus, Culex pipiens quinqusfasciatus, Anopheles sinensis, Cx.tritaeniorhynchus and Cx.pipiens pallens in the Three Gorges Reservoir area. The density of mosquito in room was higher than outside. Conclusion The density of mosquito tended to decline from 1997 to 2007, and mosquito monitoring should be strengthened.
