The species composition and seasonal population dynamics of mosquitoes trapped in the Belek Region of Turkey are described. Eight traps (four New Jersey light traps and four CO2 baited traps) were activated weekly at four different sampling sites (wooded area, open field, village, and road edge). Between May and December, 1997, 4,542 specimens representing seven species (Culex pipiens, Culex tr...

We describe the full genetic characterization of an insect-specific flavivirus (ISF) from Culex theileri (Theobald) mosquitoes collected in Portugal. This represents the first isolation and full characterization of an ISF from Portuguese mosquitoes. The virus, designated CTFV, for Culex theileri flavivirus, was isolated in the C6/36 Stegomyia albopicta (=Aedes albopictus) cell line, and failed ...

Abstract The subgenus Culex L. includes species involved in summer–autumn arbovirus transmission but studies during winter are scarce temperate Argentina. Female specimens were collected host-seeking at dry-ice-baited traps autumn–winter–spring two sites Córdoba City 2016 and 2017. morphologically identified dissected to determine the follicular developmental stage (gonotrophic activity). Femal...

Three members of the Culex pipiens complex mosquitoes, Culex pipiens L. (including the pipiens and molestus forms) and Culex torrentium Martini, occur in the European part of Russia. The geographical and biotopic distribution of these mosquitoes was studied using molecular-genetic methods for their identification. They included Wolbachia infection, sizes of ITS2 of rDNA, polymerase chain reacti...

A field study was conducted to evaluate two CDC gravid trap attractants available for the West Nile virus surveillance program in New York State (NYS). According to potential attractiveness, a common lawn sod in NYS, Kentucky bluegrass (Poa pratensis) infusion and a rabbit chow infusion were compared for attractiveness to primary West Nile virus vectors, Culex mosquitoes. Attractiveness of each...

A study of crepuscular and night-biting mosquitoes was conducted at remote settlements along the Padauiri River, middle Negro River, state of Amazonas, Brazil. Collections were performed with human bait and a CDC-light trap on three consecutive days per month from June 2003-May 2004. In total, 1,203 h of collection were performed, of which 384 were outside and 819 were inside houses. At total o...

In Tunisia, Culex pipiens plays a role in the high annoyance experienced by most urban cities, suburban and rural areas. Resistance to Pirimiphos-methyl was analyzed in five populations of Culex pipiens collected in central Tunisia. Bioassays were performed over different larvae samples. All samples were resistant to Pirimiphos-methyl. The study of the mechanisms involved in this resistance sho...
