The esterase B gene is amplified 32-fold in an organophosphorus insecticide resistant strain, Shinjuku, of Culex pipiens molestus. The amplified gene was revealed to cluster in single extended chromosomal region (ECR) of chromosome 2 by fluorescence in situ hybridization on salivary gland chromosomes. The ECR appeared to be homogeneously non-staining with DAPI, orcein or Giemsa stains. In the F...
Millions of people die each year as a result of pathogens transmitted by mosquitoes. However, the morphological identification of mosquito species can be difficult even for experts. The identification of morphologically indistinguishable species, such as members of the Anopheles maculipennis complex (Diptera: Culicidae), and possible hybrids, such as Culex pipiens pipiens/Culex pipiens molestus...
We investigated the spatial distribution and pyrethroid susceptibility of the mosquito larvae belonging to Aedes albopictus and Culex pipiens group in catch basins located in parks in Nagasaki city, Nagasaki, Japan. Among the 308 parks located in the central regions of the city, 194 were investigated. Cx. pipiens group larvae were collected from 31 sites; larvae of Ae. albopictus, from 34 sites...

Culex is a genus of mosquitoes belonging to the family Culicidae. These species are primary vectors for diseases like West Nile virus, St. Louis encephalitis, lymphatic filariasis, and agricultural pests. The distributed all over world with overlapping distribution. To date, it assumed that molestus ecotype originated evolved in London underground tunnels during WWII, when people took shelter. ...
Mosquitoes (Diptera, Culicidae) occur in natural, urban, and peri-urban areas throughout the globe. Although the characteristics of urban and peri-urban habitats differ from those of natural habitats in many ways (e.g., fragmentation, pollution, noise, and light), few studies have examined the population connectivity of mosquitoes in urban areas. To obtain an overview of the species composition...
