experimental transmission of zika virus by mosquitoes from central europe.mosquitoes collected in germany in 2016, including culex pipiens pipiens biotype pipiens, culex torrentium and aedes albopictus, as well as culex pipiens pipiens biotype molestus (in colony since 2011) were experimentally infected with zika virus (zikv) at 18 °c or 27 °c. none of the culex taxa showed vector competence for zikv. in contrast, aedes albopictus were susceptible for zikv but only at 27 °c, with transmission rates similar to an aedes aegypti laboratory colony tested in parallel.201728106528
resource limitation, habitat segregation, and species interactions of british tree-hole mosquitoes in nature.the insect fauna of water-filled tree holes in southern britain consists primarily of the mosquitoes aedes geniculatus, anopheles plumbeus, culex torrentium, and a benthic detritivorous fauna that includes primarily the scirtid beetle prionocyphon serricornis and the chironomid midge metriocnemus martinii. culex torrentium has been documented only relatively recently in tree holes but all three species of mosquitoes partition the resource in space and time. when mosquito larvae were forced to co ...199228313718
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
culex torrentium mosquitoes from germany are negative for wolbachia.wolbachia (rickettsiales: anaplasmataceae) infects a wide range of arthropods, including several mosquito species. the bacterium is known to induce a plethora of phenotypes in its host, examples being the reproductive phenotype cytoplasmic incompatibility or resistance against infection with arboviruses. the latter is especially relevant when assessing the vector competence of mosquito species for emerging arboviruses. thus, knowledge of wolbachia infection status is important for the assessment ...201728906572
species composition and abundance of mosquito larvae in relation with their habitat characteristics in mazandaran province, northern iran.mosquitoes transmit a variety of diseases to humans. their abundance and distribution are related to the characteristics of larval habitats. mosquito larvae were collected from 120 natural and artificial habitats in 30 villages of 16 counties using standard 350 ml dippers and pipette, on a monthly basis from may-december 2014 in mazandaran province, northern iran. larval habitat characteristics were recorded separately, based on the conditions of the habitats (permanent or temporary, stagnant or ...201728956526
avian plasmodium in eastern austrian mosquitoes.insect vectors, namely mosquitoes (diptera: culicidae), are compulsory for malaria parasites (plasmodium spp.) to complete their life cycle. despite this, little is known about vector competence of different mosquito species for the transmission of avian malaria parasites.201728962620

detection of usutu, sindbis, and batai viruses in mosquitoes (diptera: culicidae) collected in germany, 2011⁻2016.due to the emergence of non-endemic mosquito vectors and the recent outbreaks of mosquito-borne diseases, mosquito-borne pathogens are considered an increasing risk to public and animal health in europe. to obtain a status quo regarding mosquito-borne viruses and their vectors in germany, 97,648 mosquitoes collected from 2011 to 2016 throughout the country were screened for arboviruses. mosquitoes were identified to species, pooled in groups of up to 50 individuals according to sampling location ...201830041410
forced salivation as a method to analyze vector competence of mosquitoes.vector competence is defined as the potential of a mosquito species to transmit a mosquito-borne virus (mobovirus) to a vertebrate host. viable virus particles are transmitted during a blood meal via the saliva of an infected mosquito. forced salivation assays allow determining the vector potential on the basis of single mosquitoes, avoiding the use of animal experiments. the method is suitable to analyze a large number of mosquitoes in one experiment within a short period of time. forced saliva ...201830148488
experimental infection and transmission competence of sindbis virus in culex torrentium and culex pipiens mosquitoes from northern sweden.sindbis virus (sinv) is a mosquito-borne alphavirus known to infect birds and cause intermittent outbreaks among humans in fenno-scandia. in sweden, the endemic area has mainly been in central sweden. recently, sinv infections have emerged to northern sweden, but the vectorial efficiency for sinv of mosquito species in this northern region has not yet been ascertained.201930300110
dna barcodes corroborating identification of mosquito species and multiplex real-time pcr differentiating culex pipiens complex and culex torrentium in iran.identifying mosquito species is a fundamental step in risk assessment and implementation of preventative strategies. moreover, culex pipiens is the most widespread mosquito vector in several regions of iran and is the main vector for transmission of west nile virus (wnv). mosquitoes were collected at 14 sites in northern regions of iran in 2015 and 2016. a subset of mosquito specimens was selected for identification confirmation using a dna-barcoding technique. construction of a phylogenetic tre ...201830427929
first record and morphological characterization of an established population of aedes (hulecoeteomyia) koreicus (diptera: culicidae) in germany.the east asian mosquito species aedes koreicus was recorded out of its native range for the first time in belgium in 2008. since then, several other european populations or single individuals have been observed throughout europe with reports from italy, switzerland, european russia, slovenia, germany and hungary. the italian population seems to be the only one that is expanding rapidly, so the swiss population very likely derives from it.201830558660
protozoan parasites in culex pipiens mosquitoes in vienna.avian malaria (plasmodium spp.) and kinetoplastid (trypanosoma spp.) parasites are common vector-borne pathogens in birds worldwide; however, knowledge about vector competence of different mosquito species is currently lacking. for a pilot project examining vector competence of mosquitoes of the culex pipiens complex and culex torrentium for protozoan parasites in the city of vienna, 316 individual mosquitoes were sampled in the months june-august 2017 around the campus of the veterinary univers ...201930783859
dna-aided identification of culex mosquitoes (diptera: culicidae) reveals unexpected diversity in underground cavities in austria.subterranean cavities serve as resting places and hibernation shelters for mosquitoes. in europe, members of the genus culex are often the most abundant insects on cave walls. culex pipiens l., the common house mosquito, exists in two physically very similar, yet genetically and ecologically distinct biotypes (or forms, 'f.'), namely cx. pipiens f. pipiens and cx. pipiens f. molestus. autogeny and stenogamy of the latter form have been interpreted as adaptations to underground habitats. the epig ...201930919062
culex torrentium: a potent vector for the transmission of west nile virus in central europe.the continuous circulation of west nile virus (wnv) in central, south and east europe and its recent detection in several dead birds and two horses in germany highlights the need for information on wnv vector competence of mosquitoes from central europe. therefore, three common culex species (culex pipiens biotype pipiens, culex pipiens biotype molestus and culex torrentium) from germany were orally infected with wnv and kept at 18 °c, 21 °c, 24 °c or 27 °c for 14 or 21 days post infection (dpi) ...201931146418
sindbis virus polyarthritis outbreak signalled by virus prevalence in the mosquito vectors.polyarthritis and rash caused by sindbis virus (sinv), was first recognised in northern europe about 50 years ago and is known as ockelbo disease in sweden and pogosta disease in finland. this mosquito-borne virus occurs mainly in tropical and sub-tropical countries, and in northern europe it is suggested to cause regularly reoccurring outbreaks. here a seven-year cycle of sinv outbreaks has been referred to in scientific papers, although the hypothesis is based solely on reported human cases. i ...201931465453
meta-transcriptomic comparison of the rna viromes of the mosquito vectors culex pipiens and culex torrentium in northern europe.mosquitoes harbor an extensive diversity of 'insect-specific' rna viruses in addition to those important to human and animal health. however, because most studies of the mosquito virome have been conducted at lower latitudes, little is known about the diversity and evolutionary history of rna viruses sampled from mosquitoes in northerly regions. here, we compared the rna virome of two common northern mosquito species, culex pipiens and culex torrentium, collected in south-central sweden. followi ...201931698792
surveillance of mosquito vectors in southern sweden for flaviviruses and sindbis virus.there are three human pathogenic bird-viruses transmitted by culex mosquitoes in europe: the alphavirus sindbis and the flaviviruses west nile virus and usutu virus. cases of sindbis fever occur in the north while the flaviviruses are reported from southern europe. in this study, 7933 culex pipiens/torrentium mosquitoes from southern sweden were screened by rtqpcr for these viruses. none of the mosquitoes were positive for viral rna. the importance of mosquito species composition is discussed as ...201931853338
