环境变化与微小按蚊入侵房屋关系的研究

为了比较不同生态环境中微小按蚊(Anopheles minimus)入侵人房和不同生境微小按蚊群落学特征,本研究采用CDC诱蚊灯人房通宵捕蚊。结果显示东方红村/龙塘村2002~2003年间入侵人房的微小按蚊前者多于后者,其高峰相对密度为41.53、39.6/5.88、24.16捕获率为95.0、92.5/85.0、97.5,优势度为61.69、61.73/33.23、45.39。研究中还发现观察区内同时存在A、C两型,入侵人房以C型占大多数,逐月入侵人房以C型占绝对优势。本研究表明东方红村由于开发造成孳生地数量改变,导致微小按蚊种群数量的增加。

STUDY ON THE RELATIONSHIP BETWEEN THE ENVIRONMENT CHANGING WITH THE HOUSE INVADING OF ANOPHELES MINIMUS

In order to study the houses invading and community characteristics of An.minimus in different environment,the CDC traps were adopt to catch the mosquitoes in human houses.Two bio-type of An.minimus, A type and C type,were trapped in houses synchronously,and the C type account for large part of the houses invading An.minimus in each month and throughout the investigation period.The results make it clear that there was more Anopheles minimus in new built county houses than those in old county house,the Anopheles minimus is the dominant mosquitoes in the developing county houses,which might attribute to the change of breeding sites in the developing county.
