A systematic survey was carried out between April 1993 and March 1994 to study the distribution and prevalence of anopheline mosquito species in two malaria-prone areas situated in the foothills of Darjeeling district. Ten different species of Anopheles viz. An. aconitus, An. annularis, An. barbirostris, An. culicifacies, An. fluviatilis, An. hyrcanus group, An. maculatus, An. subpictus, An. vagus and An. varuna were collected. Per man hour density of mosquitoes collected was 4.5 and the most prevalent species was An. vagus, comprising 63% of the total catch. An. fluviatilis, an efficient vector of malaria in the foothill regions of India, was reported for the first time from this area. However, the classical vector of this region viz. An. minimus was altogether absent during the course of the present survey. All the ten species were found in cowsheds while, human habitation harboured higher population density (56.5%) of the total catch.
1993年4月至1994年3月期间，开展了一项系统性调查，以研究大吉岭地区山麓两个疟疾高发地区按蚊种类的分布和流行情况。共采集到10种不同的按蚊，即 aconitus按蚊、annularis按蚊、barbirostris按蚊、culicifacies按蚊、fluviatilis按蚊、hyrcanus按蚊组、maculatus按蚊、subpictus按蚊、vagus按蚊和varuna按蚊。每人工小时采集到的蚊子密度为4.5只，最常见的种类是vagus按蚊，占总捕获量的63%。fluviatilis按蚊是印度山麓地区疟疾的有效传播媒介，该地区首次报告发现这种按蚊。然而，本次调查期间，该地区的经典传播媒介极小按蚊完全未出现。所有这10种按蚊均在牛棚中被发现，而人类居住地捕获的按蚊种群密度更高（占总捕获量的56.5%）。
