“…Density of Culex quinquefasciatus in rainy season and in summer was significantly higher (P<0.05) than that of winter. Density of this species in rainy season was not significantly higher than those of winter and summer unlikely with those of other villages as earlier reported by Chandra and Hati (1996) and Rudra and Chandra (1998). In these areas foul water sources are not as common as found in urban and rural areas of different situations where there are mainly stagnant drains.…”

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

“…Statistical analysis (Z test) revealed significant difference in infection and infectivity rate in different seasons (p \ 0.05) which was found to be similar to the findings of Chandra et al (2007) and Dixit et al (2009). Per man hour density of the study area during the study period was quite higher than previous records (Rudra and Chandra 1998). PMD of filarial vector, C. quinquefasciatus was higher (p \ 0.05) in the rainy season.…”

Lymphatic filariasis is one of the major public health concern in India, and Bankura district of West Bengal is one of the main filaria prone area of the country. is the causative organism and is the main vector of lymphatic filariasis in India. In the present study, infection and infectivity rate of filarial vector were determined. The molecular characterization, DNA fingerprinting and phylogenetic analysis of was done. In the study area, overall vector infection and infectivity rates were 4.83 and 0.97%, respectively. The infection and infectivity rate were found to be higher in rainy season and lower in summer season. The AT and GC content of SNC Bankura (Accession No. JF930705) were 55.59 and 44.41%, respectively. The phylogenetic tree was prepared following neighbour joining, maximum parsimony, minimum evolutionary and UPGMA methods. The study revealed that. SNC Bankura (JF930705) showed 100% similarity with. (Accession No. EU370161). The cluster containing, SNC Bankura () and (EU370161) branched with (M15309) with 62% bootstrap value. SNC Bankura (), (EU370161) and (M15309) branched with (AF188120) with 78% bootstrap value.

“…Men were apparently more affected than women evidenced by a greater (to some extent) microfilaria rate and filarial disease rate as also reported in other studies. [9][10] Women wore more clothes than men and this greater exposure of men to mosquito bites might be one of the causes of this difference. The microfilaria rate was higher in the age group of 21-30 years and the disease rate as well as the mmd was higher in the 31-40 year age group, which indicate that working age groups (21-40 years) were more affected by the disease.…”

The state of West Bengal, India, has a long coastline with the Bay of Bengal. No information exists regarding filarial epidemiology and its vector in these coastal areas. The present study was designed to assess the epidemiology of lymphatic filariasis and the role of available mosquitoes as its vector in eight coastal villages around Digha, West Bengal. Night blood samples of 4016 individuals were collected and each of them was examined clinically for any manifestations of the disease. Overall, microfilaria rate, mean microfilarial density and disease rate were 9.06%, 8.63% and 7.72%, respectively. The causative parasite was identified as Wuchereria bancrofti and Culex quinquefasciatus was incriminated as the vector responsible. Vector infection and infectivity rates were assessed to be 12.5% and 0.73%, respectively. The human blood index of human-house-frequenting vector population was 70%. Vector density, vector infection, infectivity rates and human blood index were higher in the rainy season in the study area. Overall, the filarial situation was bad and, as a measure, single-dose diethylcarbamazine citrate (6 mg/kg body weight) treatment was given to all the microfilariaemic patients. Night blood samples of the treated individuals were tested for microfilariae on days 10 and 365, which revealed interesting results.
