| dispersal behavior of adult snow melt mosquitoes in the upper rhine valley, germany. | the dispersal behavior of female snow melt mosquitoes was studied in two forests in rhineland-palatinate, germany, from april to august 1993. both cdc-light-traps and human bait collections were used to collect mosquitoes. sampling sites were chosen along a west-east and a north-south transect in treated and untreated parts of a forest with a village in its center. around this settlement, breeding sites within a radius of 1.5 to 2.5 km were treated. it could be shown that this buffer zone is suf ... | 1997 | 9221732 |
| larvicidal properties of decomposed leaf litter in the subalpine mosquito breeding sites. | the larvicidal properties of the dietary leaf litter originating from the vegetation surrounding the subalpine mosquito breeding sites were investigated by using 10-month decomposed alder leaf litter against different field collections of culicine taxa of various ecological origin (aedes cantans, aedes caspius, aedes cataphylla, aedes detritus, aedes punctor, aedes pullatus, aedes rusticus, anopheles claviger, culex hortensis, culex pipiens, culiseta morsitans). larvae originating from sites wit ... | 2002 | 11804062 |
| long lasting persistence of bacillus thuringiensis subsp. israelensis (bti) in mosquito natural habitats. | background: the detrimental effects of chemical insecticides on the environment and human health have lead to the call for biological alternatives. today, one of the most promising solutions is the use of spray formulations based on bacillus thuringiensis subsp. israelensis (bti) in insect control programs. as a result, the amounts of bti spread in the environment are expected to increase worldwide, whilst the common belief that commercial bti is easily cleared from the ecosystem has not yet bee ... | 2008 | 18941501 |
| genome scan in the mosquito aedes rusticus: population structure and detection of positive selection after insecticide treatment. | identification of genes involved in local adaptation is particularly challenging for species functioning as a network of interconnected populations undergoing frequent extinctions-recolonizations, because populations are submitted to contrasted evolutionary pressures. using amplified fragment length polymorphism markers, population genetic structure of the mosquito aedes rusticus was analysed in five geographical areas of the french rhône-alpes region. we included a number of sites that were tre ... | 2010 | 20015143 |
| amplified fragment length homoplasy: in silico analysis for model and non-model species. | aflp markers are widely used in evolutionary genetics and ecology. however the frequent occurrence of non-homologous co-migrating fragments (homoplasy) both at the intra- and inter-individual levels in aflp data sets is known to skew key parameters in population genetics. geneticists can take advantage of the growing number of full genome sequences available for model species to study aflp homoplasy and to predict it in non-model species. | 2010 | 20459671 |
| insecticide susceptibility of aedes aegypti and aedes albopictus in central africa. | abstract: background: aedes aegypti (linnaeus, 1762) and aedes albopictus (skuse, 1894) are the main vectors of dengue (denv) and chikungunya (chikv) viruses worldwide. as there is still no vaccine or specific treatment for denv and chikv, vector control remains the cornerstone of prevention and outbreak control. unfortunately, vector control programs are facing operational challenges with mosquitoes becoming resistant to commonly used insecticides in several areas through the world. throughout ... | 2011 | 21575154 |
| 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 ... | 2016 | 27259984 |
| 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. | 2015 | 26122427 |
| 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 ... | 2015 | 26663040 |
| 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 ... | 2015 | 25889666 |
| 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 ... | 2013 | 24157510 |

| 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 ... | 0 | 25229703 |
| 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. | 2014 | 24924481 |
| 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 ... | 2015 | 26271277 |
| 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. | 2014 | 25174354 |
| 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 ... | 0 | 24037105 |
| resistance to bio-insecticides or how to enhance their sustainability: a review. | after more than 70 years of chemical pesticide use, modern agriculture is increasingly using biological control products. resistances to conventional insecticides are wide spread, while those to bio-insecticides have raised less attention, and resistance management is frequently neglected. however, a good knowledge of the limitations of a new technique often provides greater sustainability. in this review, we compile cases of resistance to widely used bio-insecticides and describe the associated ... | 2015 | 26150820 |
| recent range expansion and agricultural landscape heterogeneity have only minimal effect on the spatial genetic structure of the plant pathogenic fungus mycosphaerella fijiensis. | understanding how geographical and environmental features affect genetic variation at both the population and individual levels is crucial in biology, especially in the case of pathogens. however, distinguishing between these factors and the effects of historical range expansion on spatial genetic structure remains challenging. in the present study, we investigated the case of mycosphaerella fijiensis-a plant pathogenic fungus that has recently colonized an agricultural landscape characterized b ... | 2012 | 22990310 |
| high prevalence and lineage diversity of avian malaria in wild populations of great tits (parus major) and mosquitoes (culex pipiens). | avian malaria studies have taken a prominent place in different aspects of evolutionary ecology. despite a recent interest in the role of vectors within the complex interaction system of the malaria parasite, they have largely been ignored in most epidemiological studies. epidemiology of the disease is however strongly related to the vector's ecology and behaviour, and there is a need for basic investigations to obtain a better picture of the natural associations between plasmodium lineages, vec ... | 2012 | 22506060 |
| circulation of dirofilaria repens, setaria tundra, and onchocercidae species in hungary during the period 2011-2013. | dirofilaria repens and recently dirofilaria immitis are known to be endemic in hungary. since there is no related research on dirofilaria carrier mosquito species from hungary, we conducted a three-year mosquito surveillance study between 2011 and 2013. during the study period we examined 23,139 female mosquitoes with a generic filaria-specific taqman pcr assay, and characterized them by sequencing a 500 bp segment of 12s rrna. an important result of our study was the detection of setaria tundra ... | 2015 | 26412142 |
| seasonal dynamics and habitat specificity of mosquitoes in an english wetland: implications for uk wetland management and restoration. | we engaged in field studies of native mosquitoes in a cambridgeshire fen, investigating a) the habitat specificity and seasonal dynamics of our native fauna in an intensively managed wetland, b) the impact of water-level and ditch management, and c) their colonization of an arable reversion to flooded grassland wetland expansion project. studies from april to october, 2010 collected 14,000 adult mosquitoes (15 species) over 292 trap-nights and ∼4,000 pre-imaginal mosquitoes (11 species). open fl ... | 2015 | 26047189 |
