Abstract

Sibling species A of Anopheles subpictus (fresh water form) has been incriminated and established as a primary vector of malaria for the first time in an area (Tarakeswar, West Bengal) in Indian subcontinent with a natural sporozoite (Plasmodium vivax) rate of 0.32% (2/621). Moderate anthropophilic index (41.0) and high survival rate per gonotrophic cycle (0.58) indicate its efficiency as vector. Coincidence of higher malaria cases and higher density of An. subpictus in the study area is of high relevance. No natural sporozoite infection was detected in other anophelines available like An. vagus, An. annularis and An. barbirostris.
亚按蚊在印度某地区作为疟疾主要媒介的作用
在印度次大陆的一个地区(西孟加拉邦Tarakeswar),亚按蚊(淡水形式)的兄弟种A首次被证实为疟疾的主要媒介,其天然孢子(间日疟原虫)率为0.32%(2/621)。适度的亲人类指数(41.0)和每个淋养循环的高存活率(0.58)表明其是有效的载体。高疟疾病例与高安蚊密度的巧合。Subpictus在研究区域是高度相关的。在其他按蚊中未发现天然孢子虫感染。迷走神经,一个。环星和安。barbirostris。
