| west nile virus infection in mosquitoes, birds, horses, and humans, staten island, new york, 2000. | west nile (wn) virus transmission in the united states during 2000 was most intense on staten island, new york, where 10 neurologic illnesses among humans and 2 among horses occurred. wn virus was isolated from aedes vexans, culex pipiens, cx. salinarius, ochlerotatus triseriatus, and psorophora ferox, and wn viral rna was detected in anopheles punctipennis. an elevated weekly minimum infection rate (mir) for cx. pipiens and increased dead bird density were present for 2 weeks before the first h ... | 2001 | 11589172 |
| mosquito and arbovirus activity during 1997-2002 in a wetland in northeastern mississippi. | the species composition and population dynamics of adult mosquitoes in a wetland near iuka, ms, were analyzed over a 6-yr period (1997-2002) and reverse transcription-polymerase chain reaction (pcr) detection rates of arboviruses determined during five of those years. blood meals of three likely vector species were identified using a pcr-based method that allows identification of the host to species. culex erraticus (dyar & knab) composed 51.9% of the population during the 6-yr period with 295 f ... | 2004 | 15185956 |
| epidemiology of west nile virus in connecticut: a five-year analysis of mosquito data 1999-2003. | two hundred and ten isolations of west nile virus (wnv) were obtained from 17 mosquito species in six genera in statewide surveillance conducted in connecticut from june through october, 1999-2003. culex pipiens (86), culex salinarius (32), culex restuans (26), culiseta melanura (32), and aedes vexans (12) were implicated as the most likely vectors of wnv in the region based on virus isolation data. culex pipiens was abundant from july through september and is likely involved in early season enz ... | 2004 | 15682518 |
| host-seeking height preferences of aedes albopictus (diptera: culicidae) in north central florida suburban and sylvatic locales. | the response of aedes albopictus to the bg-sentinel, omni-directional-fay-prince, and mosquito magnetx traps was evaluated in four suburban and four sylvatic habitats in north-central florida to ascertain potential height preference of this species. these traps, which are primarily designed to attract diurnal mosquitoes, were set at 1 and 6 m and were evaluated during 40 trapping periods over 4 mo. we collected 45,640 mosquitoes, representing 26 species from 10 genera, the most common being aede ... | 2009 | 19645296 |
| potential sympatric vectors and mammalian hosts of venezuelan equine encephalitis virus in southern mexico. | arboviruses are important zoonotic agents with complex transmission cycles and are not well understood because they may involve many vectors and hosts. we studied sympatric wild mammals and hematophagous mosquitoes having the potential to act as hosts and vectors in two areas of southern mexico. mosquitoes, bats, and rodents were captured in calakmul (campeche) and montes azules (chiapas), between november 2010 and august 2011. spleen samples from 146 bats and 14 rodents were tested for molecula ... | 2017 | 28384059 |
