dependence of co2-baited suction trap captures on temperature variations.in order to provide better standardized co2-baited trap samples, the relationship between sample size and evening temperatures was studied. adult mosquitoes were collected for 3 h centered on sunset by an automatic interval suction trap baited with co2 in the upper rhine valley, germany. aedes vexans females were most abundant, and their blood-seeking activity showed a significant correlation with the evening's average temperature (r = 0.76, p < or = 0.05). a higher degree of correlation was obt ...19957616192
[examination of mosquitoes collected in southern moravia in 2006-2008 tested for arboviruses].the main goals of the study were to carry out virus isolation attempts on vero cell cultures from mosquitoes collected in southern moravia (breclav district, czech republic) and to identify the isolates using a microtiter virus neutralization test. a total of 9.742 female mosquitoes belonging to 13 species were examined, and three viral strains were isolated, all from the mosquitoes collected in 2006: two of these isolates were identified as tahyna orthobunyavirus (both obtained from aedes vexan ...201020925246
host-feeding patterns of mosquito species in germany.mosquito-borne pathogens are of growing importance in many countries of europe including germany. at the same time, the transmission cycles of most mosquito-borne pathogens (e.g. viruses or filarial parasites) are not completely understood. there is especially a lack of knowledge about the vector capacity of the different mosquito species, which is strongly influenced by their host-feeding patterns. while this kind of information is important to identify the relevant vector species, e.g. to dire ...201627259984
temporal variation in sindbis virus antibody prevalence in bird hosts in an endemic area in sweden.sindbis virus (sinv) is a mosquito-borne bird virus that occasionally causes human disease in fennoscandia, suggested to have cyclic 7-year intervals between outbreaks. reliable data on human infections in sweden is however lacking. here we investigated the sinv antibody prevalence among birds in a swedish area endemic to sinv to scrutinize if a cyclic variation in antibody prevalence is present in the natural host of sinv. serum from birds were sampled in the summers of 2002-2004 and 2009 in th ...201627579607
vector-virus interactions and transmission dynamics of west nile virus.west nile virus (wnv; flavivirus; flaviviridae) is the cause of the most widespread arthropod-borne viral disease in the world and the largest outbreak of neuroinvasive disease ever observed. mosquito-borne outbreaks are influenced by intrinsic (e.g., vector and viral genetics, vector and host competence, vector life-history traits) and extrinsic (e.g., temperature, rainfall, human land use) factors that affect virus activity and mosquito biology in complex ways. the concept of vectorial capacit ...201324351794
replication of west nile virus, rabensburg lineage in mammalian cells is restricted by temperature.the genus flavivirus currently consists of approximately 80 single-strand positive-sense rna viruses. these replicate in a range of hosts including myriad vertebrate, insect, and tick species. as a consequence of this broad host range, the majority of flaviviruses can be propagated in most vertebrate and insect cell cultures. this ability to infect arthropods and vertebrates usually is essential for maintenance of these viruses in nature. but recently, there has been the discovery of a number of ...201223241081
monitoring of west nile virus in mosquitoes between 2011-2012 in hungary.west nile virus (wnv) is a widely distributed mosquito-borne flavivirus. wnv strains are classified into several genetic lineages on the basis of phylogenetic differences. whereas lineage 1 viruses are distributed worldwide, lineage 2 wnv was first detected outside of africa in hungary in 2004. since then, wnv-associated disease and mortality in animal and human hosts have been documented periodically in hungary. after the first detection of wnv from a pool of culex pipiens mosquitoes in 2010, s ...025229703
characterization of rabensburg virus, a flavivirus closely related to west nile virus of the japanese encephalitis antigenic group.rabensburg virus (rabv), a flavivirus with ∼76% nucleotide and 90% amino acid identity with representative members of lineage one and two west nile virus (wnv), previously was isolated from culex pipiens and aedes rossicus mosquitoes in the czech republic, and phylogenetic and serologic analyses demonstrated that it was likely a new lineage of wnv. however, no direct link between rabv and human disease has been definitively established and the extent to which rabv utilizes the typical wnv transm ...201222724010

co-circulation of usutu virus and west nile virus in a reed bed ecosystem.mosquito-borne flaviviruses are a major public health threat in many countries worldwide. in central europe, west nile virus (wnv) and usutu virus (usuv), both belonging to the japanese encephalitis virus group (flaviviridae) have emerged in the last decennium. surveillance of mosquito vectors for arboviruses is a sensitive tool to evaluate virus circulation and consequently to estimate the public health risk.201526459018
field evaluation of four widely used mosquito traps in central europe.to monitor adult mosquitoes several trapping devices are available. these are differently constructed and use various mechanisms for mosquito attraction, thus resulting in different trapping sensitivities and efficacies for the various species. mosquito monitoring and surveillance programs in europe use various types of mosquito traps, but only a few comparisons have been conducted so far. this study compared the performance of four commercial trapping devices, which are commonly used in europe.201424924481
dirofilaria repens microfilariae in aedes vexans mosquitoes in slovakia.in this study, we screened field-caught mosquitoes for presence of dirofilaria spp. by using a polymerase chain reaction (pcr) assay. potential occurrence of dirofilaria repens and dirofilaria immitis microfilariae was examined in 3,600 mosquitoes of eight species (aedes vexans, aedes cinereus, aedes rossicus, culex pipiens, culiseta annulata, ochlerotatus sticticus, ochlerotatus cantans and ochlerotatus caspius) collected from five locations in two districts (kosice and trebisov) of eastern slo ...201323846240

lack of evidence for the presence of schmallenberg virus in mosquitoes in germany, 2011.in 2011, a novel orthobunyavirus of the simbu serogroup was discovered near the german-dutch border and named schmallenberg virus (sbv). so far, sbv genome has been detected in various field-collected culicoides species; however, other members of the simbu serogroup are also transmitted by mosquitoes.201425174354
