| entomologic studies after a st. louis encephalitis epidemic in grand junction, colorado. | in 1986, after a st. louis encephalitis epidemic in grand junction, colorado, in 1985, vector mosquitoes in the city were surveyed to correlate their bionomics and infection rates with the occurrence of human disease. no human cases were reported, but mosquito surveillance disclosed st. louis encephalitis virus in culex tarsalis and culex pipiens pipiens. mosquitoes were collected with gravid traps designed to attract cx. p. pipiens and with centers for disease control light traps. culex p. pipi ... | 1988 | 2899394 |

| role of corvids in epidemiology of west nile virus in southern california. | the invasion of different southern california landscapes by west nile virus (wnv) and its subsequent amplification to epidemic levels during 2004 enabled us to study the impact of differing corvid populations in three biomes: the hot colorado desert with few corvids (coachella valley), the southern san joaquin valley (kern county) with large western scrub-jay but small american crow populations, and the cool maritime coast (los angeles) with a large clustered american crow population. similar su ... | 2006 | 16619622 |
| entomological studies along the colorado front range during a period of intense west nile virus activity. | to better understand the ecology of west nile virus transmission in northern colorado, field studies were conducted in larimer and weld counties from september 2003 through march 2005. during summer studies, 18,540 adult mosquitoes were collected using light traps and gravid traps. west nile virus rna was detected in 24 of the 2,140 mosquito pools tested throughout the study area in 2003 and 2004. culex tarsalis had the highest minimum infection rate (mir) in both 2003 (mir = 34.48) and in 2004 ... | 2007 | 17536366 |
| persistent west nile virus transmission and the apparent displacement st. louis encephalitis virus in southeastern california, 2003-2006. | west nile virus (family flaviviridae, genus flavivirus, wnv) invaded the colorado desert biome of southern california during summer 2003 and seemed to displace previously endemic st. louis encephalitis virus (family flaviviridae, genus flavivirus, slev, an antigenically similar flavivirus in the japanese encephalitis virus serocomplex). western equine encephalomyelitis virus (family togaviridae, genus alphavirus, weev), an antigenically distinct alphavirus, was detected during 2005 and 2006, ind ... | 2008 | 18533445 |
| mosquito species richness, composition, and abundance along habitat-climate-elevation gradients in the northern colorado front range. | we exploited elevation gradients (1,500-2,400 m) ranging from plains to montane areas along the poudre river and big thompson river in the northern colorado front range to determine how mosquito species richness, composition, and abundance change along natural habitat-climate-elevation gradients. mosquito collections in 26 sites in 2006 by using co2-baited cdc light traps yielded a total of 7,136 identifiable mosquitoes of 27 species. commonly collected species included aedes vexans (meigen) (n ... | 2008 | 18714885 |
| relationship between distance from major larval habitats and abundance of adult mosquitoes in semiarid plains landscapes in colorado. | we examined the relationship between distance from major larval habitats and abundance of adult mosquitoes in the semiarid plains landscape characteristic of eastern colorado. mosquito collection was conducted from late june to early august 2007 and included trap locations at distances ranging from <10 m up to 20-150 m and 160-373 m from three major larval habitats: one area along a river corridor and two small reservoirs. the study yielded 65,140 mosquitoes of 14 species, and five species were ... | 2009 | 19960672 |
| seasonal patterns for entomological measures of risk for exposure to culex vectors and west nile virus in relation to human disease cases in northeastern colorado. | we examined seasonal patterns for entomological measures of risk for exposure to culex vectors and west nile virus (family flaviviridae, genus flavivirus, wnv) in relation to human wnv disease cases in a five-county area of northeastern colorado during 2006-2007. studies along habitat/elevation gradients in 2006 showed that the seasonal activity period is shortened and peak numbers occur later in the summer for culex tarsalis coquillett females in foothills-montane areas >1600 m compared with pl ... | 2009 | 19960707 |
