Mosquito species composition of the Dooars of West Bengal, India

Abstract

The sub Himalayan Dooars belt of Jalpaiguri district in West Bengal is an endemic focal area for malaria. A survey of mosquitoes was conducted from four sites of the Central Dooars during 2006 -07. The sampling sites were at Nagrakata, Binnaguri, Ballaguri, and Totopara. The different endophilic mosquito species recorded from hutments and tea garden dwellings Armigeres subalbatus and Toxorhynchites splendens. Per man-hour density (PMD) of all species were determined for the mosquitoes species. Besides a general rise in mosquito population, the predatory species, T. splendens was higher in rainy season than that of winter and summer. Anophlines comprised 55.17% of the total indoor resting collections and the different Anopheles species densities ranged from 3.79% to 12.24% of the total mosquito population. Malaria incidence in these areas is noted to be very high, particularly in Nagrakata and its surroundings. Total Culex density was 20.32% of the entire mosquito collection. Aedes and mansonia population were 7.55% and 4.98% respectively. Common mosquito growing areas were tea garden channels, streams, riverbeds, jungle pools, paddy fields, domestic muddy water passages and septic

Mosquito diversity and their larval habitats from the northern part of West Bengal

“…They also reported that the evenness components varied greatly, ranging from 54.03 to 95.03% in this region. In the same year, mosquitoes were surveyed from Nagrakata, Binnaguri, Ballaguri and Totopara in the central dooars [18] . In this study, 16 mosquito species were found in human habitation.…”

“…Anopheles aitkenii [16] 27. Anopheles barbirostris [16][17][18] 28. Anopheles hyrcanus [16,17,18] 29.…”

“…Anopheles jeyporiensis [17] 49. Anopheles minimus [18] 50. Anopheles varuna [18] The majority of the recorded species are belonging to the genus Anopheles.…”

“…Anopheles minimus [18] 50. Anopheles varuna [18] The majority of the recorded species are belonging to the genus Anopheles. In the other hand genus Toxorhynchites and Orthopodomyia are accounted for the least number of species.…”

DNA-based identification and control of disease spreading mosquito species: A review

“…minimus and An. baimaii are predominantly available vector species [24]; there quantity is lowering down [25]. Besides, these are replaced by A. culicifacies in their locations [26].…”
