对云南省南部新建移民东方红村和现有的龙塘村中三带喙库蚊与伪杂鳞库蚊种群动态情况进行了比较。结果表明:2个村庄中这2种媒介蚊虫的种群动态趋势不同;东方红村房屋内,除6月三带喙库蚊种群密度比伪杂鳞库蚊明显要高以外,其它月份二者种群密度差异不明显(P>0.05);整个诱集期间,伪杂鳞库蚊的种群密度(D)和种群优势度(d)在东方红村房屋(D=10只.灯-1,d=0.04)与牛舍(D=52只.灯-1,d=0.06)中都比龙塘村房屋(D=33只.灯-1,d=0.10)与牛舍(D=99只.灯-1,d=0.09)中的低。表明云南南部地区新移民村建设中,乙脑媒介种群随着环境开发产生变化。
The population dynamics of Culex tritaeniorhynchus and Culex pipiens pallens in Dongfanghong Village, a newly built immigrant in southern Yunnan Province, and the existing Longtang Village were compared. The results showed that the trend of population dynamics of these two vector mosquitoes was different in the two villages. In Dongfang Hongcun houses, except for the population density of Culex tritaeniorhynchus in June was significantly higher than that in Culex pseudoreria, (P> 0.05). During the whole trapping period, population density (D) and population dominance (d) (D = 33, lamp -1, d = 0.10) and cowshed (D = 99) and lamp house (D = -1, d = 0.09). This indicates that in the construction of new immigrant villages in the southern part of Yunnan Province, the population of JE media changed with the development of the environment.
