| host feeding patterns of connecticut mosquitoes (diptera: culicidae). | blood-engorged coquillettidia perturbans, psorophora ferox, culex, culiseta, and aedes mosquitoes were collected principally by sweep net from salt marsh and woodland habitats in connecticut. of the 570 mosquitoes tested, precipitin tests identified the origins of 517 blood meals and revealed distinct host feeding patterns. aedes mosquitoes fed chiefly on mammals; a. abserratus, a. cantator, and a. vexans showed selectivity for cattle and (or) horses. a. cantator also obtained blood from avian h ... | 1977 | 17310 |
| a survey of mosquitoes breeding in used tire stockpiles in connecticut. | a larval survey of nine used tire disposal sites in connecticut, was conducted from june through october 1987. no larvae of aedes albopictus were uncovered indicating that this mosquito is not yet established in the state. however, eight other mosquito species in four genera were found. the most abundant and widely distributed species found breeding in permanent tire dumps were ae. atropalpus, ae. triseriatus and culex restuans. culex pipiens was the second most common culex species followed by ... | 1988 | 3199116 |
| west nile virus from female and male mosquitoes (diptera: culicidae) in subterranean, ground, and canopy habitats in connecticut. | in total, 93,532 female mosquitoes (diptera: culicidae) were captured in traps placed in subterranean (catch basin), ground (approximately 1.5 m above ground), and canopy (approximately 7.0 m above ground) habitats in stamford and stratford, ct, during 2003-2005. culex pipiens l. was the most abundant (64.8%) of the 31 species identified. significantly greater numbers of cx. pipiens were captured in canopy-placed mosquito magnet experimental traps, and significantly greater numbers were collecte ... | 2006 | 17017241 |
| importance of vertical and horizontal transmission of west nile virus by culex pipiens in the northeastern united states. | west nile virus (wnv) has become established in the northeastern united states, where mosquitoes are inactive during winter. there have been no documented studies to explain how this virus survives winter and reinitiates infection in spring. we report that wnv was vertically transmitted to 2 f(1) female culex pipiens from a naturally infected female collected in stratford, connecticut. one vertically infected f(1) female, which was 168 days old, fed on a hamster that died 8 days later of west ni ... | 2006 | 17083043 |
| nocturnal activity of mosquitoes (diptera: culicidae) in a west nile virus focus in connecticut. | six species of mosquitoes (diptera: culicidae) were collected in sufficient numbers for analysis in segregating traps set at 2-h intervals by using co2 and light as attractants in a west nile virus (family flaviviridae, genus flavivirus, wnv) focus in stratford, ct. the kolmogorov-smirnov one-sided test for two samples was used to analyze the data. mosquito activity began shortly before sunset and continued until shortly after sunrise the next morning. all species had geometric means that were s ... | 2007 | 18047212 |
| genetic insights into the population structure of culex pipiens (diptera: culicidae) in the northeastern united states by using microsatellite analysis. | members of the culex pipiens complex are considered as biting nuisance and vectors of important arbo-viruses including west nile virus (wnv). to analyze the genetic structure of urban and rural populations of cx. pipiens form pipiens and gain insights into behavioral implications, mosquitoes were collected from established wnv transmission foci in connecticut from october 2006 through october 2007, examined by using microsatellite markers, and compared with other populations from neighboring sta ... | 2008 | 18840738 |
| modeling the spatial distribution of mosquito vectors for west nile virus in connecticut, usa. | the risk of transmission of west nile virus (wnv) to humans is associated with the density of infected vector mosquitoes in a given area. current technology for estimating vector distribution and abundance is primarily based on centers for disease control and prevention (cdc) light trap collections, which provide only point data. in order to estimate mosquito abundance in areas not sampled by traps, we developed logistic regression models for five mosquito species implicated as the most likely v ... | 2006 | 16989568 |
| multiple isolations of eastern equine encephalitis and highlands j viruses from mosquitoes (diptera: culicidae) during a 1996 epizootic in southeastern connecticut. | thirty-six isolations of eastern equine encephalitis virus were obtained from 8 species of mosquitoes collected from 5 september through 18 october 1996 during an epizootic in southeastern connecticut. these included culiseta melanura (coquillett) (19 isolates), culex pipiens l. (8), culiseta morsitans (theobald) (3), aedes sollicitans (walker) (2), aedes cantator (coquillett) (1), aedes trivittatus (coquillett) (1), aedes vexans (meigen) (1), and coquillettidia perturbans (walker) (1). isolatio ... | 1998 | 9615549 |
| a two-year evaluation of elevated canopy trapping for culex mosquitoes and west nile virus in an operational surveillance program in the northeastern united states. | the effectiveness of co2-baited centers for disease control and prevention miniature light traps elevated in the tree canopy (approximately 7.6 m) was compared with light traps placed at ground level (approximately1.5 m) and grass-sod infused gravid traps for collecting culex pipiens, culex restuans, and culex salinarius and detecting west nile virus (wnv) activity in an operational surveillance program that encompassed 12 ecologically diverse sites in connecticut in 2004 and 2005. more than twi ... | 2007 | 17847845 |
| 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 |
| control of mosquitoes in catch basins in connecticut with bacillus thuringiensis israelensis, bacillus sphearicus, and spinosad. | catch basins are a major source of culex pipiens pipiens, cx. restuans, and aedes japonicus in northeastern usa. vectobac cg (bacillus thuringiensis israelensis [bti]), vectolex cg (bacillus sphaericus [bs]), and vectobac 12as (bti), each applied at maximum label rate of 1.8 g, 1.8 g, and 0.193 ml per catch basin, respectively, significantly reduced the numbers of larvae for 1 wk. the dosages on the labels for treatment of mosquito larvae in catch basins, where mosquito breeding is continuous, a ... | 2011 | 21476447 |
| mosquito surveillance for west nile virus in connecticut, 2000: isolation from culex pipiens, cx. restuans, cx. salinarius, and culiseta melanura. | fourteen isolations of west nile (wn) virus were obtained from four mosquito species (culex pipiens [5], cx. restuans [4], cx. salinarius [2], and culiseta melanura [3]) in statewide surveillance conducted from june through october 2000. most isolates were obtained from mosquitoes collected in densely populated residential locales in fairfield and new haven counties, where the highest rates of dead crow sightings were reported and where wn virus was detected in 1999. minimum field infection rate ... | 2001 | 11585530 |
| isolation of west nile virus from mosquitoes, crows, and a cooper's hawk in connecticut. | west nile (wn) virus, a mosquito-transmitted virus native to africa, asia, and europe, was isolated from two species of mosquitoes, culex pipiens and aedes vexans, and from brain tissues of 28 american crows, corvus brachyrhynchos, and one cooper's hawk, accipiter cooperii, in connecticut. a portion of the genome of virus isolates from four different hosts was sequenced and analyzed by comparative phylogenetic analysis. our isolates from connecticut were similar to one another and most closely r ... | 1999 | 10600741 |
