vector competence of peruvian mosquitoes (diptera: culicidae) for a subtype iiic virus in the venezuelan equine encephalomyelitis complex isolated from mosquitoes captured in peru.we evaluated mosquitoes collected in the amazon basin, near iquitos, peru, for their susceptibility to a subtype iiic strain of the venezuelan equine encephalomyelitis complex. this virus had been previously isolated from a pool of mixed culex vomerifer and cx. gnomatos captured near iquitos, peru, in 1997. after feeding on hamsters with viremias of about 10(8) plaque-forming units of virus per ml, cx. gnomatos was the most efficient vector. other species, such as ochlerotatus fulvus and psoroph ...200616646325
diversity of mosquito vectors (diptera: culicidae) in caxiuanã, pará, brazil.this paper presents a study based on ecological parameters represented by diversity and richness indices applied in a community of mosquitoes (diptera: culicidae), at the national forest of caxiuanã, melgaço municipality, state of pará, in the brazilian amazon. a total of 25,433 specimens of culicids were collected in the study, from five field collection periods, over 10 months, between 2005 and 2006. specimens were collected in four heights of the forest (ground level, 8 m, 16 m, and 30 m-cano ...201222997514
vector competence of peruvian mosquitoes (diptera: culicidae) for epizootic and enzootic strains of venezuelan equine encephalomyelitis virus.mosquitoes collected in the amazon basin, near iquitos, peru, were evaluated for their susceptibility to epizootic (iab and ic) and enzootic (id and ie) strains of venezuelan equine encephalomyelitis (vee) virus. after feeding on hamsters with a viremia of approximately 10(8) plaque-forming units of virus per milliliter, culex (melanoconion) gnomatus sallum, huchings, & ferreira, culex (melanoconion) vomerifer komp, and aedes fulvus (wiedemann) were highly susceptible to infection with all four ...200011126537
susceptibility of peruvian mosquitoes to eastern equine encephalitis virus.mosquitoes were collected in the amazon basin, near iquitos, peru, and used in experimental studies to evaluate their susceptibility to strains of eastern equine encephalitis virus (eeev) that were isolated from mosquitoes captured within 20 km of iquitos. when fed on hamsters or chickens with a viremia of 4105 plaque-forming units (pfu) of eeev/ml, culex pedroi sirivanakarn and belkin, aedesfulvus (wiedemann), psorophora albigenu (peryassu), and psorophoraferox (von humboldt) were susceptible t ...200818714873
natural enzootic vectors of venezuelan equine encephalitis virus, magdalena valley, colombia.to characterize the transmission cycle of enzootic venezuelan equine encephalitis virus (veev) strains believed to represent an epizootic progenitor, we identified natural vectors in a sylvatic focus in the middle magdalena valley of colombia. hamster-baited traps were placed into an active forest focus, and mosquitoes collected from each trap in which a hamster became infected were sorted by species and assayed for virus. in 18 cases, a single, initial, high-titered mosquito pool representing t ...200312533281
mites (acari: trombidiformes) parasitizing mosquitoes (diptera: culicidae) in an atlantic forest area in southern brazil with a new mite genus country record.in this study, a total of 4146 culicids collected in an atlantic forest area in paraná state, southern brazil were examined for the presence of mites. forty larval parasitengone mites (arrenurus spp., arrenuridae; durenia spp., trombellidae; microtrombidium spp., microtrombidiidae) parasitized 25 specimens of mosquitoes, with the intensity varying from one to nine mites attached. most mites were found on aedes serratus/nubilus, culex vomerifer, cx. pedroi and cx. sacchettae. the overall percenta ...201627085719
