first nationwide surveillance of culex pipiens complex and culex torrentium mosquitoes demonstrated the presence of culex pipiens biotype pipiens/molestus hybrids in germany.mosquitoes and other arthropods may transmit medically important pathogens, in particular viruses such as west nile virus. the presence of suitable hosts and competent vectors for those zoonotic viruses is essential for an enzootic transmission, which is a prerequisite for epidemics. to establish reliable risk projections, it is an urgent need for an exact identification of mosquito species, which is especially challenging in the case of sibling species, such as culex. pipiens pipiens biotypes p ...201324039724
species composition, co-occurrence, association and affinity indices of mosquito larvae (diptera: culicidae) in mazandaran province, northern iran.although considerable progress has been made in the past years in management of mosquito borne diseases such as malaria, dengue, yellow fever and west nile fever through research in biology and ecology of the vectors, these diseases are still major threats to human health. therefore, more research is required for better management of the diseases. this investigation provides information on the composition, co-occurrence, association and affinity indices of mosquito larvae in mazandaran province, ...201626805471
trapping biases of culex torrentium and culex pipiens revealed by comparison of captures in cdc traps, ovitraps, and gravid traps.we evaluate three trapping methods for their effectiveness at capturing culex pipiens and culex torrentium, both enzootic vectors of bird-associated viruses in europe. the comparisons, performed in two regions in sweden, were among cdc traps baited with carbon dioxide, gravid traps, and ovitraps baited with hay infusion. the proportions of the two culex species in a catch differed between trap types, with cdc traps catching a lower proportion of cx. torrentium than both gravid traps and ovitraps ...201526047196
wide recognition of culex pipiens and lack of detection of culex torrentium through biomolecular differentiation of mosquitoes in the emilia-romagna region, northern italy.the culex pipiens complex includes species with reported differences in vector competence for arthropod-borne viruses, many of which are of significant importance to human health such as the west nile virus and the sindbis virus. this group of mosquitoes is difficult to distinguish morphologically; particularly as adult females. in europe, the two species of the complex, culex pipiens linnaeus 1758 and culex torrentium martini 1925, are often found sympatrically. with the aim to characterize the ...201627477051
ecological distribution and cq11 genetic structure of culex pipiens complex (diptera: culicidae) in italy.mosquitoes in the culex pipiens complex are considered to be involved in the transmission of a range of pathogens, including west nile virus (wnv). although its taxonomic status is still debated, the complex includes species, both globally distributed or with a more limited distribution, morphologically similar and characterised by different physiological and behavioural traits, which affect their ability as vectors. in many european countries, cx. pipiens and its sibling species culex torrentiu ...201626741494
winter activity and aboveground hybridization between the two biotypes of the west nile virus vector culex pipiens.culex (cx.) pipiens mosquitoes are important vectors of west nile virus (wnv). in europe, the species cx. pipiens consists of two biotypes, pipiens and molestus, which are morphologically identical, but differ in behavior. typical behavior of the molestus biotype is the ability to remain active during winter, whereas the pipiens biotype enters diapause. the current paradigm is that the two biotypes occur sympatrically in southern europe, but occur in isolated above- and belowground populations i ...201526394124
west nile virus and usutu--a threat to poland.in recent years emergence of new infectious diseases and the growing spread of pathogens to new areas is observed. most of these pathogens are zoonotic viruses and their transmission route is from animals to humans and vice versa. these so called emerging and re-emerging pathogens that were present previously only in africa and asia are becoming a threat to european countries. these include, e.g. west nile virus and usutu virus. the aim of the study is to present the clinical course of infection ...201627344466
culex pipiens and culex torrentium populations from central europe are susceptible to west nile virus infection.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 of culex mosquitoes over two subsequent seasons at two geographically distinct sampling areas in german ...201628616480
