Abstract

A 2-yr entomological study was carried out in Kerala, south India, to identify the mosquito vectors of Japanese encephalitis (JE) virus and to determine their seasonal abundance and infection. In total, 150,454 mosquitoes belonging to five genera and 18 species were collected from vegetation surrounding cattle sheds and pigsties in villages at dusk. Culex tritaeniorhynchus Giles (66.7%) was the most abundant species, with increases in numbers associated with rice cultivation. JE virus isolations were made from Cx. tritaeniorhynchus and Mansonia indiana Edwards. Based on high abundance and frequent JE virus infection, Cx. tritaeniorhynchus seems to be the most important vector, whereas Ma. indiana is probably a secondary vector.

摘要

在印度南部喀拉拉邦开展了一项为期两年的昆虫学研究，以确定日本脑炎（JE）病毒的蚊媒，并确定其季节丰度和感染情况。黄昏时分，从村庄牛棚和猪圈周围的植被中总共采集了150454只蚊子，分属于5个属18个种。三带喙库蚊（Culex tritaeniorhynchus Giles）（66.7%）是数量最多的物种，其数量增加与水稻种植有关。从三带喙库蚊和印度曼蚊（Mansonia indiana Edwards）中分离出了JE病毒。基于高丰度和频繁的JE病毒感染，三带喙库蚊似乎是最重要的病媒，而印度曼蚊可能是次要病媒。
