摘要:

  【摘要】 目的 探讨澜沧江中下游地区居民点蚊类物种多样性及地理分布格局。方法 2007年9-11月用CDC诱蚊灯对澜沧江5个县9个调查点的居民区进行夜间成蚊的调查取样,对所获蚊虫进行分类计数,然后对数据进行统计学分析。 结果 共捕获蚊虫4682只,分属6属28种(亚种)。结果分析发现,澜沧江中下游地区居民点蚊类的物种多样性与纬度梯度呈负相关(r=-0.3219),与海拔梯度显示负相关(r=-0.4238)。结论 三带喙库蚊是澜沧江中下游地区居民点蚊类的优势种,中华按蚊、环带库蚊、骚扰阿蚊、致倦库蚊、美彩按蚊和棕头库蚊是该区域的常见种。蚊虫多样性与调查点所处的纬度梯度和海拔梯度有一定的联系。

Abstract:

  【Abstract】 Objective To find out the relationship between the mosquito diversity in residential areas and its geographical distribution pattern along the midstream and downstream areas of Lantsang. Methods CDC light?traps were used to collect mosquitoes in 9 residential areas of 5 counties along the Lantsang. Results A total of 4682 mosquitoes belonged to 28 species of 6 genus were collected. The results showed that the Shannon?Wiener’s diversity index (H′) had a negative correlation with latitudes(r=-0.3219) and elevations(r=-0.4238). Conclusion  In the residential areas of Lantsang, Culex tritaeniorhynchus was the dominant species,  Anopheles sinensis, Cx.annulus,  Armigeres subalbatus,  Cx.pipiens quinguefasciatus, An.splendidus and Cx.fuscocephala were the common species. The Shannon?Wiener’s diversity index (H′)   had the relationship with the latitudes and elevations.
