Entomological, parasitological and serological surveys were conducted between October 1989 and November 1990 in 27 villages (population 33,250) belonging to three topographically different areas of district Allahabad, viz. Gangapar, Doaba and Yamunapar. A good correlation existed in all the three areas between malaria incidence vis-a-vis An. culicifacies sibling species composition and malaria antibodies titre in the populations. In Gangapar and Doaba villages, An. culicifacies densities were low and the proportions of vector species A and C were much less than that of species B, the non-vector species. Low endemicity of malaria was supported by low antibody titres observed in the population. In contrast, in Yamunapar villages An. culicifacies densities were high, species A and C together were almost equal to species B, and malaria incidence as well as antibody titre were high. Based on these observations, district Allahabad, Uttar Pradesh, could be divided into two zones, low malaria transmission zone--Gangapar and Doaba areas and high malaria transmission zone--Yamunapar area.
1989年10月至1990年11月期间，在北方邦阿拉哈巴德县三个地形不同的区域（即甘加帕尔、多巴和亚穆纳帕尔）的27个村庄（人口33250人）开展了昆虫学、寄生虫学和血清学调查。在所有这三个区域，疟疾发病率与库蚊按蚊姐妹种组成以及人群中的疟疾抗体滴度之间均存在良好的相关性。在甘加帕尔和多巴村庄，库蚊按蚊密度较低，媒介种类A和C的比例远低于非媒介种类B。人群中观察到的低抗体滴度支持了疟疾的低流行率。相比之下，在亚穆纳帕尔村庄，库蚊按蚊密度较高，种类A和C的总和几乎与种类B相等，疟疾发病率和抗体滴度也较高。基于这些观察结果，北方邦阿拉哈巴德县可分为两个区域，即低疟疾传播区——甘加帕尔和多巴地区，以及高疟疾传播区——亚穆纳帕尔地区。
