| surveillance for west nile virus in american white pelicans, montana, usa, 2006-2007. | west nile virus (wnv)-associated deaths of american white pelican (pelecanus erythrorhynchos) chicks have been recognized at various nesting colonies in the united states since 2002. we evaluated american white pelican nesting colonies in sheridan county, montana, usa, for an association between wnv-positive pelican carcasses and human west nile neuroinvasive disease. persons in counties hosting affected colonies had a 5x higher risk for disease than those in counties with unaffected colonies. w ... | 2010 | 20202414 |
| vector competence of the stable fly (diptera: muscidae) for west nile virus. | in 2006-2007, stable flies, stomoxys calcitrans (l.) (diptera: muscidae), were suspected of being enzootic vectors of west nile virus (family flaviviridae, genus flavivirus, wnv) during a die-off of american white pelicans (pelecanus erythrorhynchos gmelin) (pelecanidae) in montana, usa. wnv-positive stable flies were observed feeding en masse on incapacitated, wnv-positive pelicans, arousing suspicions that the flies could have been involved in wnv transmission among pelicans, and perhaps to li ... | 2011 | 21661328 |
| evaluation of methods for collecting blood-engorged mosquitoes from habitats within a wildlife refuge. | mortality of american white pelican (pelecanus erythrorhynchos) chicks attributed to west nile virus (wnv) prompted field studies on the bionomics of mosquitoes on a wildlife refuge in northern montana. one component of these studies was to identify blood meal sources for culex tarsalis, the primary vector of wnv in the region, and the potential bridge vectors aedes vexans and culiseta inornata. to accomplish this, 3 methods were evaluated to collect bloodfed mosquitoes: a gasoline powered aspir ... | 2013 | 23923324 |
| mosquito and west nile virus surveillance in northeast montana, u.s.a., 2005 and 2006. | mosquito and west nile virus (wnv) surveillance was conducted on a national wildlife refuge in northeast montana in 2005 and 2006, during which outbreaks of wnv in a colony of american white pelicans (pelecanus erythrorhynchos gmelin) (pelecaniformes: pelecanidae) resulted in juvenile mortality rates of ∼ 31%. both years, floodwater species ochlerotatus dorsalis (meigen) (diptera: culicidae), aedes vexans (meigen) (diptera: culicidae) and ochlerotatus flavescens (muller) (diptera: culicidae) com ... | 2014 | 23647177 |
