Mosquito borne diseases have a great impact on human and animal health throughout the world including Bangladesh. An entomological survey was conducted at the Bangladesh Agricultural University (BAU) campus and its surrounding areas from January to June, 2013 to identify the mosquito larvae and to investigate the different breeding site preferences of mosquitoes. Mosquito larvae were collected using dipper, ladle spoon, dropper and pipette from rice field, botanical garden, dairy farm, poultry farm, drains, lakes, ponds, staff quarters, residential halls and cattle sheds. A total of 1397 mosquito larvae were collected from the places. Ten species of mosquitoes under three genera were identified. The recorded genera were Anopheles (An.), Culex (Cx.) and Aedes (Ae.). The collected species were An. bengalensis, An. vagus, Cx. fuscocephala, Cx. quinquefasciatus, Cx. tritaeniorhynchus, Cx. gelidus, Cx. vishnui, Cx. whitmorei, Cx. sitiens and Ae. albopictus. Among the collected larvae, Culex was found most prevalent (64.3%), followed by Anopheles (26.7%) and Aedes were the least prevalent (9.0%). The results of this study provide evidence that drains were the most common aquatic habitat of Anopheles and Culex larvae in Boyra, Kewatkhali and Balashpur. In BAU campus, agronomy fields were found having the highest percentage (35.2%) of mosquito larvae than the other places of the campus. This study suggests that although drains and rice fields are the richest habitats, since Anopheles and Culex can breed in all available breeding habitats. This larval survey will help us to conduct future mosquito control activities and provide us useful information to schedule larvicide’s application to control the mosquito borne diseases in the study areas as well as throughout the country.DOI: http://dx.doi.org/10.3329/bjvm.v13i1.23962Bangl.

Mosquitoes harbor an extensive diversity of ‘insect-specific’ RNA viruses in addition to those important to human and animal health. However, because most studies of the mosquito virome have been conducted at lower latitudes, little is known about the diversity and evolutionary history of RNA viruses sampled from mosquitoes in northerly regions. Here, we compared the RNA virome of two common northern mosquito species, Culex pipiens and Culex torrentium, collected in south-central Sweden. Following bulk RNA-sequencing (meta-transcriptomics) of 12 libraries, comprising 120 specimens of Cx. pipiens and 150 specimens of Cx. torrentium, we identified 40 viruses (representing 14 virus families) of which 28 were novel based on phylogenetic analysis of the RNA-dependent RNA polymerase (RdRp) protein. Hence, we documented similar levels of virome diversity as in mosquitoes sampled from the more biodiverse lower latitudes. Many viruses were also related to those sampled on other continents, indicative of a widespread global movement and/or long host–virus co-evolution. Although the two mosquito species investigated have overlapping geographical distributions and share many viruses, several viruses were only found at a specific location at this scale of sampling, such that local habitat and geography may play an important role in shaping viral diversity in Culex mosquitoes.

The ecology of West Nile virus (WNV) in the Danube Delta Biosphere Reserve (Romania) was investigated by combining studies on the virus genetics, phylogeography, xenosurveillance and host-feeding patterns of mosquitoes. Between 2014 and 2016, 655,667 unfed and 3842 engorged mosquito females were collected from four sampling sites. Blood-fed mosquitoes were negative for WNV-RNA, but two pools of unfed Culex pipiens s.l./torrentium collected in 2014 were tested positive. Our results suggest that Romania experienced at least two separate WNV lineage 2 introductions: from Africa into Danube Delta and from Greece into south-eastern Romania in the 1990s and early 2000s, respectively. The genetic diversity of WNV in Romania is primarily shaped by in situ evolution. WNV-specific antibodies were detected for 19 blood-meals from dogs and horses, but not from birds or humans. The hosts of mosquitoes were dominated by non-human mammals (19 species), followed by human and birds (23 species). Thereby, the catholic host-feeding pattern of Culex pipiens s.l./torrentium with a relatively high proportion of birds indicates the species’ importance as a potential bridge vector. The low virus prevalence in combination with WNV-specific antibodies indicate continuous, but low activity of WNV in the Danube Delta during the study period.

Selection Of

Six natural terrestrial mosquito breeding habitats were recognised in the Kano Plains of Kenya by their condition, i.e. temporary or permanent, presence or absence of emergent plants, and by the chemical and physical characteristics of their water. Between September 1968 and March 1970, 13 mosquito species were found breeding in these habitats. Most species were restricted to a few habitats; only four showed a wide occurrence, being found in at least four. Anopheles gambiae Giles and Culex annulioris Theo. exploited all six habitats, suggesting that the characteristics studied were probably not critical to their selection of a breeding site. Mansonia and Coquillettidia spp. were restricted to habitats with some plants, indicating their dependence on such vegetation for respiration and protection. The indiscriminate selection of breeding sites by disease vectors, e.g. A. gambiae, A. pharoensis Theo. and Culex pipiens fatigans Wied., is worth noting in irrigation schemes.
