| surveillance for acute insecticide-related illness associated with mosquito-control efforts--nine states, 1999-2002. | ground and aerial applications of insecticides are used to control populations of adult mosquitoes, which spread such diseases as west nile virus--related illness, eastern equine encephalitis, and dengue fever. this report summarizes investigations of illnesses associated with exposures to insecticides used during 1999-2002 to control mosquito populations in nine states (arizona, california, florida, louisiana, michigan, new york, oregon, texas, and washington) (estimated 2000 population: 118 mi ... | 2003 | 12855943 |
| phylogeography and population structure of aedes aegypti in arizona. | aedes aegypti, the mosquito responsible for transmitting dengue, has colonized many cities and towns throughout arizona. determining both the migration between, and the origin of, local ae. aegypti populations is important for vector control and disease prevention purposes. amplified fragment length polymorphism was used to infer geographic structure and local substructure, and effective migration rates (m, migrants per generation) between populations, and to determine genetic differentiation be ... | 2005 | 15772327 |
| microclimate and human factors in the divergent ecology of aedes aegypti along the arizona, u.s./sonora, mx border. | this study examined the association of human and environmental factors with the presence of aedes aegypti, the vector for dengue fever and yellow fever viruses, in a desert region in the southwest united states and northwest mexico. sixty-eight sites were longitudinally surveyed along the united states-mexico border in tucson, az, nogales, az, and nogales, sonora during a 3-year period. aedes aegypti presence or absence at each site was measured three times per year using standard oviposition tr ... | 2010 | 20232228 |
| west nile virus disease and other arboviral diseases --- united states, 2010. | arthropod-borne viruses (arboviruses) are transmitted to humans primarily through the bites of infected mosquitoes and ticks. since west nile virus (wnv) was first detected in the western hemisphere in 1999, it has become the leading cause of neuroinvasive arboviral disease in the united states. however, several other arboviruses continue to cause sporadic cases and seasonal outbreaks of neuroinvasive disease (i.e., meningitis, encephalitis, or acute flaccid paralysis). this report summarizes su ... | 2011 | 21814163 |
| human and environmental factors affecting aedes aegypti distribution in an arid urban environment. | aedes aegypti has reappeared in urban communities in the southwestern u.s.a. in the 1990s after a 40-year absence. in 2003 and 2004, a systematic survey was conducted throughout metropolitan tucson, az, to identify human and environmental factors associated with ae. aegypti distribution within an arid urban area. aedes aegypti presence and abundance were measured monthly using the centers for disease control and prevention enhanced oviposition traps at sampling sites established in a grid at 3- ... | 2011 | 21805845 |
| origin of the dengue fever mosquito, aedes aegypti, in california. | dengue fever is among the most widespread vector-borne infectious diseases. the primary vector of dengue is the aedes aegypti mosquito. ae. aegypti is prevalent in the tropics and sub-tropics and is closely associated with human habitats outside its native range of africa. while long established in the southeastern united states of america where dengue is re-emerging, breeding populations have never been reported from california until the summer of 2013. using 12 highly variable microsatellite l ... | 2014 | 25077804 |
| binational dengue outbreak along the united states-mexico border - yuma county, arizona, and sonora, mexico, 2014. | dengue is an acute febrile illness caused by any of four dengue virus types (denv-1-4). denvs are transmitted by mosquitos of the genus aedes (1) and are endemic throughout the tropics (2). in 2010, an estimated 390 million denv infections occurred worldwide (2). during 2007-2013, a total of three to 10 dengue cases were reported annually in arizona and all were travel-associated. during september-december 2014, coincident with a dengue outbreak in sonora, mexico, 93 travel-associated dengue cas ... | 2016 | 27196619 |
| willingness to pay for mosquito control in key west, florida and tucson, arizona. | mosquito-borne illnesses like west nile virus (wnv) and dengue are growing threats to the united states. proactive mosquito control is one strategy to reduce the risk of disease transmission. in 2012, we measured the public's willingness to pay (wtp) for increased mosquito control in two cities: key west, fl, where there have been recent dengue outbreaks, and tucson, az, where dengue vectors are established and wnv has been circulating for over a decade. nearly three quarters of respondents in b ... | 2016 | 26903603 |
| fine scale spatial urban land cover factors associated with adult mosquito abundance and risk in tucson, arizona. | it is currently unclear what role microhabitat land cover plays in determining the seasonal spatial distribution of aedes aegypti and culex quinquefasciatus, disease vectors of dengue and west nile virus, respectively, in tucson, az. we compared mosquito abundance to sixteen land cover variables derived from 2010 naip multispectral data and 2008 lidar height data. mosquitoes were trapped with 30-9 traps from may to october of 2010 and 2011. variables were extracted for five buffer zones (10-50 m ... | 2012 | 23181866 |
| population and parity levels of aedes aegypti collected in tucson. | oviposition traps were used to follow changes in the population of aedes aegypti (l.) (diptera:culicidae) in a seven-block area in midtown region of tucson, arizona. about 20,000 eggs were collected over a period from 1 june to 14 october 2000. peak mosquito populations were correlated with the late summer rains. mosquitoes seeking a blood meal were collected and dissected to determine if they had previously fed, i.e. if they were parous. of the 241 females examined, 44% were parous, with a rang ... | 2003 | 12831130 |
