| larval feeding behavior of three co-occurring species of container mosquitoes. | interspecific differences in foraging behavior may help to determine whether the outcome of interspecific competition is coexistence or exclusion. mosquitoes in the genus culex are commonly described as foraging primarily by filtering the water column. this behavior contrasts with that of other container-dwelling genera, such as aedes and ochlerotatus, that are thought to forage primarily by browsing on container and detritus surfaces. we compared the feeding behavior of cx. pipiens, ae. albopic ... | 0 | 15707290 |
| habitat associations of eastern equine encephalitis transmission in walton county florida. | eastern equine encephalitis virus (eeev; family togaviridae, genus alphavirus) a highly pathogenic mosquito-borne virus is endemic to eastern north america. the ecology of eeev in florida differs from that in other parts of the united states; eeev in the northeastern united states is historically associated with freshwater wetlands. no formal test of habitat associations of eeev in florida has been reported. geographical information sciences (gis) was used in conjunction with sentinel chicken ee ... | 0 | 22679885 |
| the effect of multiple vectors on arbovirus transmission. | many mosquito-borne arboviruses have more than one competent vector. these vectors may or may not overlap in space and time, and may interact differently with vertebrate hosts. the presence of multiple vectors for a particular virus at one location over time will influence the epidemiology of the system, and could be important in the design of intervention strategies to protect particular hosts. a simulation model previously developed for west nile and st. louis encephalitis viruses and culex ni ... | 0 | 23741205 |
| 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 |
| the roles of mosquito and bird communities on the prevalence of west nile virus in urban wetland and residential habitats. | this study investigated the impacts of urban wetlands and their adjacent residential environments on the transmission dynamics of west nile virus (wnv) within the state of new jersey (usa). a working hypothesis was that urban wetlands decrease the local prevalence of wnv through the dilution effect from increased bird diversity, and through relative reductions in the numbers of competent avian host and mosquito species commonly associated with wnv. surveys of mosquito and bird communities were u ... | 0 | 25484570 |
| climate change impacts on west nile virus transmission in a global context. | west nile virus (wnv), the most widely distributed virus of the encephalitic flaviviruses, is a vector-borne pathogen of global importance. the transmission cycle exists in rural and urban areas where the virus infects birds, humans, horses and other mammals. multiple factors impact the transmission and distribution of wnv, related to the dynamics and interactions between pathogen, vector, vertebrate hosts and environment. hence, among other drivers, weather conditions have direct and indirect i ... | 0 | 25688020 |
| west nile virus: a re-emerging pathogen revisited. | west nile virus (wnv), a flavivirus of the flaviviridae family, is maintained in nature in an enzootic transmission cycle between avian hosts and ornithophilic mosquito vectors, although the virus occasionally infects other vertebrates. wnv causes sporadic disease outbreaks in horses and humans, which may result in febrile illness, meningitis, encephalitis and flaccid paralysis. until recently, its medical and veterinary health concern was relatively low; however, the number, frequency and sever ... | 0 | 24175211 |
| analysis of post-blood meal flight distances in mosquitoes utilizing zoo animal blood meals. | we assessed the post-blood meal flight distance of four mosquito species in a unique environment using blood meal analysis. mosquitoes were trapped at the rio grande zoo in albuquerque, nm, and the blood source of blood-engorged mosquitoes was identified. the distance from the enclosure of the animal serving as a blood source to the trap site was then determined. we found that mosquitoes captured at the zoo flew no more than 170 m with an average distance of 106.7 m after taking a blood meal. th ... | 0 | 22548540 |
| modifiable risk factors for west nile virus infection during an outbreak--arizona, 2010. | west nile virus (wnv) is the leading cause of mosquito-borne disease in the united states; however, risk factors for infection are poorly defined. we performed a case-control study to identify modifiable risk factors for wnv infection. case-patients (n = 49) had laboratory evidence of recent wnv infection, whereas control-subjects (n = 74) had negative wnv serology. we interviewed participants, surveyed households, and assessed environmental data. wnv infection was associated with living in or n ... | 0 | 22556093 |
| identification of blood meal sources in aedes vexans and culex quinquefasciatus in bernalillo county, new mexico. | culex quinquefasciatus say (diptera: culicidae) and aedes vexans meigen are two of the most abundant mosquitoes in bernalillo county, new mexico, usa. in this study, a polymerase chain reaction based methodology was used to identify the sources of blood meals taken by these two species. ae. vexans was found to take a large proportion of its meals from mammals. although less specific in terms of its blood meal preferences, cx. quinquefasciatus was found to feed more commonly on birds. the results ... | 0 | 24224615 |
| evaluation of seasonal feeding patterns of west nile virus vectors in bernalillo county, new mexico, united states: implications for disease transmission. | many mosquito species take bloodmeals predominantly from either birds or mammals. other mosquito species are less host-specific and feed readily on both. furthermore, some species tend to alter their feeding patterns over the course of the year; early in the mosquito season such species may feed primarily on a particular host type, and subsequently take an increasingly larger proportion of their bloodmeals from an alternative host type as the season progresses. we have examined the feeding patte ... | 0 | 24605477 |
| weather variability affects abundance of larval culex (diptera: culicidae) in storm water catch basins in suburban chicago. | culex pipiens l. (diptera: culicidae) and culex restuans theobald are the primary enzootic and bridge vectors of west nile virus in the eastern united states north of 36 degrees latitude. recent studies of the natural history of these species have implicated catch basins and underground storm drain systems as important larval development sites in urban and suburban locales. although the presence of larvae in these habitats is well-documented, the influence of abiotic factors on the ecology of cu ... | 0 | 22493843 |
| satellite microwave remote sensing for environmental modeling of mosquito population dynamics. | environmental variability has important influences on mosquito life cycles and understanding the spatial and temporal patterns of mosquito populations is critical for mosquito control and vector-borne disease prevention. meteorological data used for model-based predictions of mosquito abundance and life cycle dynamics are typically acquired from ground-based weather stations; however, data availability and completeness are often limited by sparse networks and resource availability. in contrast, ... | 0 | 23049143 |
| reemergence of rift valley fever, mauritania, 2010. | a rift valley fever (rvf) outbreak in humans and animals occurred in mauritania in 2010. thirty cases of rvf in humans and 3 deaths were identified. rvfv isolates were recovered from humans, camels, sheep, goats, and culex antennatus mosquitoes. phylogenetic analysis of isolates indicated a virus origin from western africa. | 0 | 24447381 |
| human and animal dirofilariasis: the emergence of a zoonotic mosaic. | dirofilariasis represents a zoonotic mosaic, which includes two main filarial species (dirofilaria immitis and d. repens) that have adapted to canine, feline, and human hosts with distinct biological and clinical implications. at the same time, both d. immitis and d. repens are themselves hosts to symbiotic bacteria of the genus wolbachia, the study of which has resulted in a profound shift in the understanding of filarial biology, the mechanisms of the pathologies that they produce in their hos ... | 0 | 22763636 |
| 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 |
| mapping eastern equine encephalitis virus risk for white-tailed deer in michigan. | eastern equine encephalitis (eee) is a mosquito-borne viral disease that is often fatal to humans and horses. some species including white-tailed deer and passerine birds can survive infection with the eee virus (eeev) and develop antibodies that can be detected using laboratory techniques. in this way, collected serum samples from free ranging white-tailed deer can be used to monitor the presence of the virus in ecosystems. this study developed and tested a risk index model designed to predict ... | 0 | 26494931 |
