| evaluation of the cdc gravid trap for the surveillance of st. louis encephalitis vectors in memphis, tennessee. | collections with cdc gravid mosquito traps on 954 trap-nights from may through september 1983 are compared to 2,608 concurrent resting site collections made in the same area of memphis, tennessee. gravid traps yielded 88 times more culex per collection and 96 times more culex per man hour. the total gravid trap catch was 135,724 mosquitoes, 99% of which were either culex pipiens or cx. restuans, whereas these species comprised only 63% of the 6,613 mosquitoes collected from resting sites. gravid ... | 1986 | 3507491 |

| oviposition activity patterns and west nile virus infection rates for members of the culex pipiens complex at different habitat types within the hybrid zone, shelby county, tn, 2002 (diptera: culicidae). | oviposition activity and west nile virus (family flaviviridae, genus flavivirus, wnv) infection rates were assessed for members of the culex pipiens complex from july through december 2002 by using gravid traps placed at four ecologically different sites in the southern portion of the hybrid zone in shelby county, tn. molecular assays identified three members of the cx. pipiens complex: cx. pipiens pipiens l., cx. p. quinquefasciatus say, and cx. p. pipiens-cx. p. quinquefasciatus hybrids (hybri ... | 2006 | 17162958 |
| west nile virus infection in mosquitoes in the mid-south usa, 2002-2005. | west nile virus (family flaviviridae, genus flavivirus, wnv) was first detected in the tennessee valley and in alabama in august 2001. in summer 2002, intensive viral activity was seen, but in subsequent years, viral activity settled into an enzootic pattern. here, we report an analysis of viral activity in the mosquito fauna in the mid-south from 2002 (the first year viral activity was detected in mosquitoes) through 2005. eight mosquito species were infected with wnv during 2002. however, vira ... | 2007 | 17294929 |
| 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 ... | 2007 | 17767413 |
| host-seeking heights, host-seeking activity patterns, and west nile virus infection rates for members of the culex pipiens complex at different habitat types within the hybrid zone, shelby county, tn, 2002 (diptera: culicidae). | host-seeking heights, host-seeking activity patterns, and west nile virus (family flaviviridae, genus flavivirus, wnv) infection rates were assessed for members of the culex pipiens complex from july to december 2002, by using chicken-baited can traps (ct) at four ecologically different sites in shelby county, tn. host-seeking height was assessed by ct placed at elevations of 3.1, 4.6, and 7.6 m during one 24-h period per month. host-seeking activity was assessed by paired ct placed at an elevat ... | 2008 | 18402144 |
