a geospatial study of the potential of two exotic species of mosquitoes to impact the epidemiology of west nile virus in maryland.we used geospatial techniques to study the potential impact of 2 exotic mosquitoes, aedes albopictus and ochlerotatus japonicus japonicus, on the epidemiology of west nile virus in maryland. these 2 species have established populations in maryland over the past 15 years. larvae of both mosquito species are found in natural and artificial water-holding cavities and containers, particularly water in tires. therefore, we used locations of licensed tire dealers and of tire dumps scheduled for clean ...200314524539
assessing capacity for surveillance, prevention, and control of west nile virus infection--united states, 1999 and 2004.indigenous human disease caused by west nile virus (wnv) was first identified in the united states in august 1999 in the greater new york city area. by the end of 2004, human wnv disease had been reported in all states except washington, hawaii, and alaska, and wnv transmission to humans had been documented by five routes: mosquito bites (principally from culex spp.), blood transfusions, organ transplantation, transplacental transfer, and breastfeeding. during 1999-2005, a total of 19,525 cases ...200616484978
mosquito landing rates on nesting american robins (turdus migratorius).we measured mosquito landing rates on adult and nestling american robins at nests with infrared cameras in washington, d.c., and maryland, united states. mosquitoes landed on nesting robins almost exclusively between dusk and dawn. the mean number of mosquito landings per night was higher for adults (123.3 +/- se 32.8) than nestlings (37.26 +/- 14.8). the fraction of mosquitoes landing at a nest on nestlings increased with decreases in adult brooding. oral swabs from nestlings at these and 13 ot ...200717767414
rainfall influences survival of culex pipiens (diptera: culicidae) in a residential neighborhood in the mid-atlantic united states.measurement of the survival and dispersal rates of mosquito vectors is an important step in designing and implementing control strategies. vector survival plays a key role in determining the intensity of pathogen transmission, and vector movement determines the spatial scale on which control efforts must operate to be effective. we provide the first estimates of field survival and dispersal rates for culex pipiens l. in north america, an important enzootic and bridge vector for west nile virus ( ...022679852
higher mosquito production in low-income neighborhoods of baltimore and washington, dc: understanding ecological drivers and mosquito-borne disease risk in temperate cities.mosquito-vectored pathogens are responsible for devastating human diseases and are (re)emerging in many urban environments. effective mosquito control in urban landscapes relies on improved understanding of the complex interactions between the ecological and social factors that define where mosquito populations can grow. we compared the density of mosquito habitat and pupae production across economically varying neighborhoods in two temperate u.s. cities (baltimore, md and washington, dc). seven ...201323583963
new distribution records of mosquitoes in washington state.routine west nile virus (wnv) surveillance in 2016 by the washington state department of health resulted in 1 new state distribution record for aedes hendersoni, bringing the total number of mosquito species reported from washington to 52. we also report new county records for aedes japonicus japonicus, aedes togoi, and culex salinarius .201728388317
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 ...200312855943
quantifying the potential pathways and locations of rift valley fever virus entry into the united states.the global invasion of west nile virus, chikungunya virus and zika virus in the past two decades suggests an increasing rate of mosquito-borne virus (arbovirus) dispersal. rift valley fever virus (rvfv) is an arbovirus identified as a high-consequence threat to the united states (usa) because of the severe economic and health consequences associated with disease. numerous studies demonstrate that the usa is receptive to rvfv transmission based on the widespread presence of competent mosquito spe ...201728191786
reproductive biology and susceptibility of florida culex coronator to infection with west nile virus.abstract ornithophilic culex species are considered the primary amplification vectors of west nile virus (wnv) in bird hosts as well as vectors responsible for epidemic transmission. culex coronator was first collected from okaloosa, santa rosa, walton, and washington counties in florida in 2005 and has since spread throughout the state. the vector competence of cx. coronator for wnv, known to be infected in nature, has not been assessed. without this knowledge, we are unable to assess this spec ...025072992
distribution of mosquitoes in washington state.the emergence of west nile virus in the united states renewed vigilance for mosquito-borne diseases and rejuvenated mosquito surveillance activities in washington state. as part of these activities, the zoonotic disease program, washington department of health, and the united states army center for health promotion and preventive medicine-west collaborated to produce this revision of the distribution of mosquitoes in washington state. data from these organizations, the us air force, and county s ...200718240520
climatic and landscape correlates for potential west nile virus mosquito vectors in the seattle region.climatic and landscape patterns have been associated with both relative mosquito abundance and transmission of mosquito-borne illnesses in many parts of the world, especially warm and tropical climes. to determine if temperature, precipitation, or degree of urbanization were similarly important in the number of potential mosquito vectors for west nile virus in the moderately temperate climate of western washington, mosquitoes were collected using cdc carbon-dioxide/light traps set throughout the ...200717633422
update: west nile virus activity--northeastern united states, january-august 7, 2000.surveillance programs initiated in response to the 1999 west nile virus (wnv) outbreak have detected increased transmission in the northeastern united states (1). seventeen states along the atlantic and gulf coasts, new york city (nyc), and washington, d.c., have conducted wnv surveillance and are reporting to cdc (1). surveillance for wnv infection includes monitoring of mosquitoes, sentinel chicken flocks, wild birds, and potentially susceptible mammals (e.g., horses and humans) (2). this repo ...200010958587
