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
francisella tularensis subspecies holarctica occurs in swedish mosquitoes, persists through the developmental stages of laboratory-infected mosquitoes and is transmissible during blood feeding.in sweden, mosquitoes are considered the major vectors of the bacterium francisella tularensis subsp. holarctica, which causes tularaemia. the aim of this study was to investigate whether mosquitoes acquire the bacterium as aquatic larvae and transmit the disease as adults. mosquitoes sampled in a swedish area where tularaemia is endemic (örebro) were positive for the presence of f. tularensis deoxyribonucleic acid throughout the summer. presence of the clinically relevant f. tularensis subsp. h ...201324057273
current status of invasive mosquito surveillance in the uk.non-native invasive mosquitoes have for many years made incursions into europe, and are now established in many european countries. the continued european importation of potential vectors and their expansion within europe increases their potential for importation and establishment in the uk. coupled with increasing numbers of returning dengue and chikungunya infected travellers, the potential exists for transmission of vector borne disease in new regions.201526122427
direct pcr of indigenous and invasive mosquito species: a time- and cost-effective technique of mosquito barcoding.millions of people die each year as a result of pathogens transmitted by mosquitoes. however, the morphological identification of mosquito species can be difficult even for experts. the identification of morphologically indistinguishable species, such as members of the anopheles maculipennis complex (diptera: culicidae), and possible hybrids, such as culex pipiens pipiens/culex pipiens molestus (diptera: culicidae), presents a major problem. in addition, the detection and discrimination of newly ...201526663040
impacts of the creation, expansion and management of english wetlands on mosquito presence and abundance - developing strategies for future disease mitigation.the incidence of mosquito-borne diseases is increasing in europe, partly due to the incursion of a number of invasive species known to be vectors of dengue and chikungunya viruses, but also due to the involvement of native species in the transmission of west nile virus and malaria. for some of these pathogens, there is a risk of the re-emergence of vector-borne diseases that were once widespread in europe, but declined partly due to large-scale land-drainage projects. some mosquito species explo ...201525889666
mosquitoes (diptera: culicidae) and their relevance as disease vectors in the city of vienna, austria.mosquitoes (diptera: culicidae) are important vectors for a wide range of pathogenic organisms. as large parts of the human population in developed countries live in cities, the occurrence of vector-borne diseases in urban areas is of particular interest for epidemiologists and public health authorities. in this study, we investigated the mosquito occurrence in the city of vienna, austria, in order to estimate the risk of transmission of mosquito-borne diseases. mosquitoes were captured using di ...201425468380
european surveillance for west nile virus in mosquito populations.a wide range of arthropod-borne viruses threaten both human and animal health either through their presence in europe or through risk of introduction. prominent among these is west nile virus (wnv), primarily an avian virus, which has caused multiple outbreaks associated with human and equine mortality. endemic outbreaks of west nile fever have been reported in italy, greece, france, romania, hungary, russia and spain, with further spread expected. most outbreaks in western europe have been due ...201324157510

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
evidence of an 'invitation' effect in feeding sylvatic stegomyia albopicta from cambodia.orientation of haematophagous insects towards a potential host is largely mediated by kairomones that, in some groups or species may include chemicals produced during feeding by the insects themselves, the so called 'invitation' effect.201425015104
a global assembly of adult female mosquito mark-release-recapture data to inform the control of mosquito-borne pathogens.pathogen transmission by mosquitos is known to be highly sensitive to mosquito bionomic parameters. mosquito mark-release-recapture (mmrr) experiments are a standard method for estimating such parameters including dispersal, population size and density, survival, blood feeding frequency and blood meal host preferences.201424946878
do mosquitoes transmit the avian malaria-like parasite haemoproteus? an experimental test of vector competence using mosquito saliva.the life-cycle of many vector-borne pathogens includes an asexual replication phase in the vertebrate host and sexual reproduction in the insect vector. however, as only a small array of parasites can successfully develop infective phases inside an insect, few insect species are competent vectors for these pathogens. molecular approaches have identified the potential insect vectors of blood parasites under natural conditions. however, the effectiveness of this methodology for verifying mosquito ...201627894354
first report outside eastern europe of west nile virus lineage 2 related to the volgograd 2007 strain, northeastern italy, 2014.west nile virus (wnv) is a flavivirus transmitted to vertebrate hosts by mosquitoes, maintained in nature through an enzootic bird-mosquito cycle. in europe the virus became of major public health and veterinary concern in the 1990s. in italy, wnv re-emerged in 2008, ten years after the previous outbreak and is currently endemic in many areas of the country. in particular, the northeastern part of italy experience continuous viral circulation, with human outbreaks caused by different genovariant ...201526265490
a review of the vector management methods to prevent and control outbreaks of west nile virus infection and the challenge for europe.west nile virus infection is a growing concern in europe. vector management is often the primary option to prevent and control outbreaks of the disease. its implementation is, however, complex and needs to be supported by integrated multidisciplinary surveillance systems and to be organized within the framework of predefined response plans. the impact of the vector control measures depends on multiple factors and the identification of the best combination of vector control methods is therefore n ...201425015004
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
pcr detection of malaria parasites and related haemosporidians: the sensitive methodology in determining bird-biting insects.knowledge about feeding preference of blood-sucking insects is important for the better understanding epidemiology of vector-borne parasitic diseases. extraction of dna from blood present in abdomens of engorged insects provides opportunities to identify species of their vertebrate hosts. however, this approach often is insufficiently sensitive due to rapid degeneration of host dna in midguts. recent studies indicate that avian malaria parasites (plasmodium spp.) and related haemosporidians (hae ...201627207268
molecular detection of dirofilaria immitis, dirofilaria repens and setaria tundra in mosquitoes from germany.as a result of globalization and climate change, dirofilaria immitis and dirofilaria repens, the causative agents of dirofilariosis in europe, continue to spread from endemic areas in the mediterranean to northern and northeastern regions of europe where autochthonous cases of dirofilarial infections have increasingly been observed in dogs and humans. whilst d. repens was recently reported from mosquitoes in putatively non-endemic areas, d. immitis has never been demonstrated in mosquitoes from ...201424433279
population dynamics.this chapter reviews aspects of population dynamics that may be conceptually important for biological control of mosquitoes. density dependent population regulation among immature stages has important implications for biological control of mosquito populations, primarily because it can lead to compensatory or overcompensatory mortality due to additions of a biological control agent. this can result in control efforts leading to no change in the target population, or actual increases in the targe ...017853611
circulation of dirofilaria repens and dirofilaria immitis in moldova.over the last two decades, a significant spread of dirofilariasis has been observed in eastern and central europe. however, data on the circulation of dirofilaria spp. in moldova were absent although direct neighbor states reported high incidence rates of human dirofilariasis.201627912786
molecular species identification, host preference and detection of myxoma virus in the anopheles maculipennis complex (diptera: culicidae) in southern england, uk.determining the host feeding patterns of mosquitoes by identifying the origin of their blood-meals is an important part of understanding the role of vector species in current and future disease transmission cycles. collecting large numbers of blood-fed mosquitoes from the field is difficult, therefore it is important to maximise the information obtained from each specimen. this study aimed to use mosquito genome sequence to identify the species within anopheles maculipennis sensu lato (an. macul ...201526271277
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
molecular detection of setaria tundra (nematoda: filarioidea) and an unidentified filarial species in mosquitoes in germany.knowledge of the potential vector role of culicidae mosquitoes in germany is very scanty, and until recently it was generally assumed that they are not involved in the transmission of anthroponotic or zoonotic pathogens in this country. however, anticipated changes in the course of global warming and globalization may alter their status.201222236560
monitoring resistance to bacillus thuringiensis subsp. israelensis in the field by performing bioassays with each cry toxin separately.bacillus thuringiensis subsp. israelensis (bti) is increasingly used worldwide for mosquito control and is the only larvicide used in the french rhône-alpes region since decades. the artificial selection of mosquitoes with field-persistent bti collected in breeding sites from this region led to a moderate level of resistance to bti, but to relatively high levels of resistance to individual bti cry toxins. based on this observation, we developed a bioassay procedure using each bti cry toxin separ ...024037105
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
prevalence-dependent costs of parasite virulence.costs of parasitism are commonly measured by comparing the performance of infected groups of individuals to that of uninfected control groups. this measure potentially underestimates the cost of parasitism because it ignores indirect costs, which may result from the modification of the competitiveness of the hosts by the parasite. in this context, we used the host-parasite system consisting of the yellow fever mosquito aedes aegypti and the microsporidian parasite vavraia culicis to address this ...200516008503
potential mosquito (diptera:culicidae) vector of dirofilaria repens and dirofilaria immitis in urban areas of eastern slovakia.this paper follows the study from 2013 focused on the molecular screening of mosquitoes as vectors of dirofilaria spp. which provided the information on aedes vexans as a potential vector of dirofilaria repens in slovakia. current entomological and molecular research indicates that ae. vexans can participate also in the transmission of dirofilaria immitis within the region. using the standard pcr method, we examined 10,500 mosquitoes (ae. vexans, ae. rossicus, anopheles maculipennis s.l., ochler ...201526391170
haemoproteus infections (haemosporida, haemoproteidae) kill bird-biting mosquitoes.haemoproteus parasites (haemosporida, haemoproteidae) are widespread; some species cause severe diseases in avian hosts. heavy haemoproteus infections are often lethal for biting midges (ceratopogonidae), which transmit avian haemoproteids, but there is no information regarding detrimental effect on other blood-sucking insects. we examined effects of haemoproteus tartakovskyi (lineage hsiskin1), haemoproteus lanii (lineages hrb1and hrbs2) and haemoproteus balmorali (lineage hcoll3) on the surviv ...201424337545
abortive long-lasting sporogony of two haemoproteus species (haemosporida, haemoproteidae) in the mosquito ochlerotatus cantans, with perspectives on haemosporidian vector research.haemoproteus spp. are cosmopolitan vector-born haemosporidian parasites, some species of which cause diseases in non-adapted birds. recent polymerase chain reaction (pcr)-based studies have detected mitochondrial cytochrome b gene lineages of these haemoproteus parasites in blood-sucking mosquitoes and speculated about possible involvement of these insects in transmission of avian haemoproteids. however, development of haemoproteus lineages has not been documented in mosquitoes. we infected 304 ...201323504040
complete sporogony of plasmodium relictum (lineage pgrw4) in mosquitoes culex pipiens pipiens, with implications on avian malaria epidemiology.plasmodium relictum (lineage pgrw4) causes malaria in birds and is actively transmitted in countries with warm climates and also temperate regions of the new world. in europe, the lineage pgrw4 has been frequently reported in many species of afrotropical migrants after their arrival from wintering grounds, but is rare in european resident birds. obstacles for transmission of this parasite in europe have not been identified. culex quinquefasciatus is an effective vector of pgrw4 malaria, but this ...201525958156

[various biological properties of aedes cantans irides iridescent virus].the sedimentation coefficient, molecular weight and the type of nucleic acid of aedes cantans iridescence virus were determined, and its proteins were analysed in a dissociating system by electrophoresis in polyacylamide gel. ultrathin sections of affected larvae were examined.20161007219
mosquitoes of north-western europe as potential vectors of arboviruses: a review.the intensification of trade and travel is linked to the growing number of imported cases of dengue, chikungunya or zika viruses into continental europe and to the expansion of invasive mosquito species such as aedes albopictus and aedes japonicus. local outbreaks have already occurred in several european countries. very little information exists on the vector competence of native mosquitoes for arboviruses. as such, the vectorial status of the nine mosquito species largely established in north- ...201931739553
wolbachia symbionts in mosquitoes: intra- and intersupergroup recombinations, horizontal transmission and evolution.many mosquitoes harbour wolbachia symbionts that could affect the biology of their host in different ways. evolutionary relationships of mosquitoes' wolbachia infection, geographical distribution and symbiont prevalence in many mosquito species are not yet clear. here, we present the results of wolbachia screening of 17 mosquito species of four genera-aedes, anopheles, coquillettidia and culex collected from five regions of eastern europe and the caucasus in 2012-2016. based on multilocus sequen ...201930708172
which mosquitoes (diptera: culicidae) are candidates for dna extraction in forensic practice?mosquitoes can be of importance in forensic context as a source of the perpretator's dna. the aim of this study was to find how can we optimize the selection of appropriate mosquito individuals. the study was based on the data of 177833 trapped female mosquitoes and 105236 individuals which were collected directly from human skin. the mean human-specific biting willingness value of aedes species was the highest (mean: 0.8). significant differences were found between the human-specific biting wil ...201830005339
[(the fauna of bloodsucking mosquitoes in the nizhny novgorod region, their infection with dirofilaria and endosymbiotic bacteria)].the fauna of bloodsucking mosquitoes in the nizhny novgorod region is represented by 11 species from 5 genera of the family culicidae. during 2014-2015, the predominant species were ochlerotatus cantans and aedes cinereus mosqui- toes in both a population aggregate and woodland. the infected mosquitoes accounted for 1.3% of their total number and were registered only in the village of fokino. the investigators identified two human pathogenic nematode species: diro- filaria immits and dirofilaria ...201730721615
[species composition and ecological peculiarities of the blood-sucking mosquito genus ochlerotatus (cantans and dorsalis species groups) (diptera, culicidae) in the novgorod region].seven mosquito species of the genus ochlerotatus ("cantans" and "dorsalis" species groups, family culicidae) were found in the novgorod region as a result of our field investigations, which have been carried out in 1996-2004. one species, ochlerotatus annulipes, was for the first time recorded in the novgorod region. distribution, biotopic and seasonal preferences of all discovered species are considered.200717285755
transient leg deformations during eclosion out of a tight confinement: a comparative study on seven species of flies, moths, ants and bees.legs in dipteran pupae are tightly packed in a zigzag configuration. changes in the shape or configuration of long podomeres during eclosion have been overlooked because they occur rapidly (in a few minutes) and the legs are hidden inside a tight opaque confinement: the puparium in the cyclorrhapha, the obtect pupa in mosquitoes. we fixed insects at different times during eclosion and obtained a temporal description of changes in leg shape. at the start of eclosion in calliphora vicina and droso ...201728549565

[bloodsucking mosquitoes (diptera: culicidae) in, the tula region are potential vectors of dirofilarias].bloodsucking mosquitoes were collected in tula and its region in may to august 2013-2014. the fauna included 17 species from 5 genera in the subfamily culicinae and anopheles maculipennis complex in the subsystem anophelinae. ochlerotatus cantans was a dominant species in the collections. the dominant species also included aedes einereus, ae. vexans, ae. geniculatus, och. diantaeus, och. intrudens, och. cataphylla, and culex pipiens. the possible value of different mosquito species dirofilaria r ...201626827580
life cycle of amblyospora weiseri n.sp.: (microsporidia) in aedes cantans (diptera, culicidae).amblyospora weiseri n.sp., parasite of the mosquito aedes cantans in czechoslovakia has two sporulation sequences: the octosporous sporulation sequence occurs in oenocytes and fat body tissue of larvae, involves meiosis and results in the formation of eight uninucleate spores (octospores) enclosed in a sporophorous vesicle and is fatal for the host. octospores are not infectious to other larvae. the oenocytic sequence localized in oenocytes of larvae and adults of both sexes probably effects tra ...201123195966
differential lipid reserves influence host-seeking behaviour in the mosquitoes aedes cantans and aedes punctor.lipid reserves of bait-caught female ae.cantans and ae.punctor mosquitoes (diptera: culicidae) were significantly higher than in teneral females. female ae.cantans given access to 10% w/v sucrose solution post-emergence showed an ability to synthesize lipid and, after 192 h, they were willing to take a bloodmeal from a human volunteer. at this point, mean lipid reserves were not significantly different from mean lipid reserves of bait-caught females. prior to 192h, females would not take a blood ...19958541588
