Culex pipiens quinquefasciatus Say and Culex pipiens pipiens Linnaeus are sibling species incriminated as important vectors of emerging and re-emerging infectious diseases worldwide. The two forms differ little morphologically and are differentiated mainly based upon ecological, behavioural, physiological and genetic traits. Within the North American zone of sympatry, populations of Cx. p. quin...

b a ckground: the role of lectins is important in interaction between pathogens and mosquito vectors. this study was performed to identify agglutinin activities of protein molecules on the midgut of culex pipiens . m e t hods: c u lex pipiens was reared in insectray condition and the midguts of males and females (blood fed and un- fed) were dissected separately in tris-hcl buffer. the extracts ...

Mosquitoes of the Culex pipiens Linné, 1758 complex are distributed all over the world, and are of great medical and veterinary importance. They are active bloodsuckers primarily in urban environments, and serve as vectors of various pathogens infecting man and/or animals. This complex is characterized by a high ecological plasticity, and intricate taxonomic structure. The complex includes C. p...

Microsatellite markers were used to genetically characterize 19 Culex pipiens complex populations from California. Two populations showed characteristics of earlier genetic bottlenecks. The overall FST value and a neighbor-joining tree suggested moderate amounts of genetic differentiation. Analyses using Structure indicated K = 4 genetic clusters: Cx. pipiens form pipiens L., Cx. quinquefasciat...

Croatian fauna consists of 50 mosquito species, and 15 of them have medical importance. Only 10 species are capable of transmitting the West Nile Virus (WNV). In Croatia the most capable vector is Culex pipiens c. According to species distribution and abundance all of Croatia is a risk area for WNV transmission. Culex pipiens c. is the dominant species (share of 5-10%) in eastern Croatia, but C...

To identify the mosquito species competent for West Nile virus (WNV) transmission, we evaluated 10 California species that are known vectors of other arboviruses or major pests: Culex tarsalis, Cx. pipiens pipiens, Cx. p. quinquefasciatus, Cx. stigmatosoma, Cx. erythrothorax, Ochlerotatus dorsalis, Oc. melanimon, Oc. sierrensis, Aedes vexans, and Culiseta inornata. All 10 became infected and we...

West Nile virus (WNV), a Flavivirus with an avian primary host, is already widespread in Europe and might also pose an infection risk to Germany, should competent mosquito vectors be present. Therefore, we analysed the ability of WNV to infect German Culex mosquitoes with special emphasis on field collected specimens of Culex torrentium and Culex pipiens biotype pipiens. We collected egg rafts ...

BACKGROUND The aim of this study was to design pictorial key and taxonomic literature of Culex pipiens complex in Iran. METHODS Larvae were collected using standard dipping methods in 13 randomly selected areas of Bushehr, Hamedan, Kerman, Khorasan-e-Razavi, Khuzistan, Mazandaran, Tehran, Sistan and Baluchistan and Yazd Provinces from April 2009 to October 2010. The data were analyzed using S...
