| species diversity, seasonal, and spatial distribution of mosquitoes (diptera: culicidae) captured in aotus monkey-baited traps in a forested site near iquitos, peru. | this study was conducted to determine the relative abundance, diversity, seasonal, and vertical distributions of potential mosquito vectors in the amazon basin, peru. a total of 66,097 mosquitoes (50 mosquito species from 12 genera) were collected from may 2001 through march 2002 at a forested site near iquitos, peru. mosquitoes were collected using aotus nancymae hershkovitz monkey-baited cdc light traps set for 12-h day and night periods at varying heights (e.g., ground and canopy) in the fore ... | 2014 | 26309298 |
| [data on mansonia titillans (walker, 1948) (diptera: culicidae) oviposition on the plant spirodela polirhyza (l.) in cuba]. | laboratory studies and field observations in relation to the preference of mansonia titillans (diptera: culicidae) to for oviposition over certain plants in 3 hatcheries of havana province (bauta and batabanó) and havana city (parque lenin) were carried out. in the laboratory, the great number of ovipositions was found to occur under the leaves of plants such as spirodela polirhiza, while under natural conditions it was observed that this can occur in egg hatcheries whenever eicchornia sp is pre ... | 1995 | 9813468 |
| enzootic mosquito vector species at equine encephalitis transmission foci in the república de panamá. | the identification of mosquito vector species present at arboviral enzootic transmission foci is important to understand transmission eco-epidemiology and to propose and implement prevention and control strategies that reduce vector-borne equine encephalitis transmission. the goal of this study was to identify mosquito species potentially involved in the transmission of enzootic equine encephalitis, in relation to their abundance and diversity at three endemic regions in the república de panamá. ... | 2017 | 28937995 |
| mansonia titillans: new resident species or infrequent visitor in chatham county, georgia, and beaufort county, south carolina, usa. | in september, october, and november 2014, adult mansonia titillans were collected at 4 separate sites near savannah in chatham county, georgia, and 1 site in muscogee county, ga, during routine mosquito surveillance. although previously recorded from beaufort county, sc, and several inland southern georgia counties, recent reports of this species from coastal georgia or south carolina are lacking. these newly captured ma. titillans specimens represent the first documented records for muscogee co ... | 2015 | 26181693 |

| prefledging mortality and the abundance of mosquitoes biting nestling barn owls (tyto alba) in florida, usa. | mosquito-borne diseases can have disastrous effects on avian populations; therefore, most studies of bird and mosquito interactions have focused on the mortality and morbidity associated with the diseases. however, the effect of mosquitoes feeding on birds, independent of disease, has not been well studied. we studied barn owls (tyto alba) nesting in artificial nest boxes in sugarcane (saccharum officinarum) fields in florida, us. to reduce mosquito effects on nestlings, we used an insecticide s ... | 2019 | 30702952 |
| scanning electron microscopy and geometric contour morphometry for identifying eggs of three amazonian species of mansonia (diptera: culicidae). | the eggs of three amazonian species of the genus mansonia (diptera: culicidae) were analyzed using morphological and morphometric characters. eggs of mansonia humeralis dyar & knab, 1916 were morphologically different from those of mansonia titillans (walker, 1848) and mansonia amazonensis (theobald, 1901), which were more similar to each other according to linear and geometric morphometry. a principal component analysis generated from elliptic fourier contour data (pc1-92.6% and pc2-2.61%) indi ... | 2019 | 31819960 |
| new county records demonstrating a northern expansion of mansonia titillans in south carolina, usa. | new county records in south carolina suggest an expansion of the recorded northern distribution of mansonia titillans in the usa. new location records of ma. titillans in beaufort county, as well as new county records in berkeley, clarendon, colleton, and georgetown counties are reported. taxonomic notes are presented that provide 100% identification accuracy. adult ma. titillans were collected between august and december 2017 from 8 locations in 5 counties in south carolina. distribution record ... | 2018 | 31442157 |
