| mosquito surveillance for west nile virus in southeastern wisconsin--2002. | in 2001, west nile virus (wnv) was identified among dead american crows and bluejays in five counties in southeastern wisconsin. in response to the introduction of wnv, a pilot mosquito surveillance program was initiated in these five southeastern wisconsin counties during the summer of 2002. forty sites were selected for surveillance one night each week during a 17-week period. mosquitoes were collected in carbon dioxide-baited light traps and gravid traps. during the study period 31,419 mosqui ... | 2003 | 15931283 |
| francisella tularensis: an arthropod-borne pathogen. | arthropod transmission of tularemia occurs throughout the northern hemisphere. few pathogens show the adaptability of francisella tularensis to such a wide array of arthropod vectors. nonetheless, arthropod transmission of f. tularensis was last actively investigated in the first half of the 20th century. this review will focus on arthropod transmission to humans with respect to vector species, modes of transmission, geographic differences and f. tularensis subspecies and clades. | 2009 | 18950590 |

| detection of francisella tularensis in alaskan mosquitoes (diptera: culicidae) and assessment of a laboratory model for transmission. | tularemia is a zoonotic disease caused by the category a bioterrorism agent francisella tularensis. in scandinavia, tularemia transmission by mosquitoes has been widely cited in the literature. we tested >2,500 mosquitoes captured in alaska and found francisella dna in 30% of pooled samples. to examine the potential for transmission of francisella by mosquitoes, we developed a mosquito model of francisella infection. larvae of anopheles gambiae giles and aedes aegypti (l.) readily ingest f. tula ... | 2010 | 20695280 |
| 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 |
| host associations of mosquitoes at eastern equine encephalitis virus foci in connecticut, usa. | eastern equine encephalitis virus (eeev) is a highly pathogenic mosquito-borne arbovirus, with active transmission foci in freshwater hardwood swamps in eastern north america, where enzootic transmission is maintained between the ornithophilic mosquito, culiseta melanura, and wild passerine birds. the role of other locally abundant mosquito species in virus transmission and their associations with vertebrate hosts as sources of blood meals within these foci are largely unknown but are of importa ... | 2016 | 27577939 |
| 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 |

| predicting the mosquito species and vertebrate species involved in the theoretical transmission of rift valley fever virus in the united states. | rift valley fever virus (rvfv) is a mosquito-borne virus in the family bunyaviridiae that has spread throughout continental africa to madagascar and the arabian peninsula. the establishment of rvfv in north america would have serious consequences for human and animal health in addition to a significant economic impact on the livestock industry. published and unpublished data on rvfv vector competence, vertebrate host competence, and mosquito feeding patterns from the united states were combined ... | 2014 | 25211133 |
| 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 |
| anthropogenic impacts on mosquito populations in north america over the past century. | the recent emergence and spread of vector-borne viruses including zika, chikungunya and dengue has raised concerns that climate change may cause mosquito vectors of these diseases to expand into more temperate regions. however, the long-term impact of other anthropogenic factors on mosquito abundance and distributions is less studied. here, we show that anthropogenic chemical use (ddt; dichlorodiphenyltrichloroethane) and increasing urbanization were the strongest drivers of changes in mosquito ... | 2016 | 27922001 |
| north american wetlands and mosquito control. | wetlands are valuable habitats that provide important social, economic, and ecological services such as flood control, water quality improvement, carbon sequestration, pollutant removal, and primary/secondary production export to terrestrial and aquatic food chains. there is disagreement about the need for mosquito control in wetlands and about the techniques utilized for mosquito abatement and their impacts upon wetlands ecosystems. mosquito control in wetlands is a complex issue influenced by ... | 2012 | 23222252 |
| 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 ... | 2014 | 25015004 |
| 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 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 ... | 2014 | 24433279 |
| roles of host species, geographic separation, and isolation in the seroprevalence of jamestown canyon and snowshoe hare viruses in newfoundland. | california serogroup viruses, including jamestown canyon virus (jcv) and snowshoe hare virus (sshv), are mosquito-borne members of the bunyaviridae family and are endemic across north america. these arboviruses are potential pathogens which occasionally cause neuroinvasive disease in humans and livestock. a neutralization assay was used to document jcv and sshv seroprevalence using blood collected from a variety of domestic and wildlife host species. these species were sampled in an island setti ... | 2012 | 22798366 |
