use of hamster-baited no. 17 trinidad mosquito traps at an eastern equine encephalomyelitis focus in tennessee.we set out no. 17 trinidad traps baited with hamsters at a swamp in tennessee, where recent eastern equine encephalomyelitis (eee) equine outbreaks had occurred, to determine which mosquito species at this site were attracted to these traps. we also set out co2-baited cdc light traps for comparison. of 11 species present in co2-baited cdc light traps, only culex (melanoconion) erraticus (dyar and knab) blood fed on hamsters in the trinidad traps. significantly less cx. erraticus mosquitoes enter ...200919645290
host choice and west nile virus infection rates in blood-fed mosquitoes, including members of the culex pipiens complex, from memphis and shelby county, tennessee, 2002-2003.the source of bloodmeals in 2,082 blood-fed mosquitoes collected from february 2002 through december 2003 in memphis and surrounding areas of shelby county, tennessee were determined. members of the genus culex and anopheles quadrimaculatus predominated in the collections. members of the cx. pipiens complex and cx. restuans were found to feed predominately upon avian hosts, though mammalian hosts made up a substantial proportion of the bloodmeals in these species. no significant difference was s ...200717767413
host feeding patterns of potential vectors of eastern equine encephalitis virus at an epizootic focus in tennessee.in 2006, 2,817 blood-fed mosquitoes were collected from the site of a 2005 eastern equine encephalitis outbreak in chester county, tn. using a polymerase chain reaction-based assay, 264 vertebrate hosts were identified from seven mosquito species. culex erraticus and cx. nigripalpus fed on a diversity of mammalian, avian, and reptilian hosts, whereas anopheles quadrimaculatus and an. punctipennis were predominantly mammalophagic. overall, 27% of cx. nigripalpus, 16% of cx. erraticus, and 7% of a ...200919706914
eastern equine encephalitis in tennessee: 2002-2008.human and equine outbreaks caused by eastern equine encephalomyelitis virus (eeev) typically occur in north america adjacent to coastal wetlands associated with the presence of culiseta melanura (coquillet) mosquitoes. eastern equine encephalomyelitis (eee) is an emerging disease in tennessee, as the first records of equine disease began in 2002. in 2006 we trapped and tested mosquitoes for eeev at hardwood swamps in western tennessee that were at the epicenter of a multi-equine outbreak in fall ...201222679883
