background: culex pipiens complex shows variations in morphological and biological characters including differ­ent biological forms and has medical and veterinary importance. because of having morphological variations, some­times it is not easy to separate this species from cx. quinquefasciatus and cx. torrentium . the aim of this study was to   identify the   culex pipiens complex species in o...

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...

The transmission of vector-borne pathogens is greatly influenced by the ecology of their vector, which is in turn shaped by genetic ancestry, the environment, and the hosts that are fed on. One group of vectors, the mosquitoes in the Culex pipiens complex, play key roles in the transmission of a range of pathogens including several viruses such as West Nile and St. Louis encephalitis viruses, a...

Nucleotide sequences of the circadian rhythm genes, period and timeless, were studied for the first time in mosquitoes Culex pipiens Linnaeus, 1758. In this work we evaluated variations of the studied genome fragments for the two forms of Culex pipiens (forma "pipiens" - mosquitoes common for aboveground habitats, forma "molestus" - underground mosquitoes). We compared Culex pipiens from Russia...

BACKGROUND Culex pipiens molestus was first reported in Shanghai in 2010. The population structures and seasonal distributions of Culex pipiens subspecies C. p. molestus, Culex pipiens pallens, and Culex pipiens quinquefasciatus are not well known. METHODS From late February to November 2013, we conducted daily field surveillance of mosquitoes at eight sites at two green lands and three resid...

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...

BACKGROUND & OBJECTIVES Taxonomic status of Culex pipiens is well-known as many years with such a wide variety of morphological and biological characteristics. These changes have been the subject of extensive investigation by many researchers. There are a little information about the morphology and molecular data of Cx. pipiens complex in Iran. The taxonomic status of the complex is very import...

Members of the Culex pipiens Linn. complex in the eastern, southern, and central United States are the primary vectors of St. Louis encephalitis virus. Although species and subspecies in the complex can be identified as 4th-instar larvae and by characters on the male genitalia, adult females cannot be identified accurately. In this study a ribosomal DNA (rDNA) segment that includes the internal...
