To examine the distribution pattern of Anopheles philippinensis and An. nivipes, mosquitoes belonging to An. philippinensis/nivipes group were collected from five sites in north-east Indian state of Assam and its adjoining areas and identified. Presence of both An. philippinensis and An. nivipes, with predominance of the latter taxon, was recorded with conformity on the basis of pupal paddle characteristics. Based on adult wing characters, 91.4% specimens were identified as An. philippinensis and 8.6% as An. nivipes with gradually increasing proportion of An. nivipes in westwardly direction. An. philippinensis/ nivipes was noted to be mid night biter, mainly exophagic and exclusively exophilic. Of the two species, An. philippinensis appears to be mostly anthropophilic and available in broken forest areas whereas An. nivipes seems to be mostly zoophilic and generally found in ecotone zones in plains areas.
为了研究菲律宾按蚊和尼氏按蚊的分布模式，从印度东北部阿萨姆邦及其毗邻地区的五个地点采集了属于菲律宾按蚊/尼氏按蚊组的蚊子并进行鉴定。根据蛹桨特征一致记录到同时存在菲律宾按蚊和尼氏按蚊，且后者占优势。根据成虫翅特征，91.4%的标本被鉴定为菲律宾按蚊，8.6%为尼氏按蚊，尼氏按蚊的比例向西逐渐增加。菲律宾按蚊/尼氏按蚊被发现为午夜叮咬者，主要在户外觅食且仅嗜室外环境。在这两个物种中，菲律宾按蚊似乎大多嗜人血，出现在破碎的森林地区，而尼氏按蚊似乎大多嗜动物血，通常在平原地区的生态交错带发现。
