vector-host interactions and epizootiology of eastern equine encephalitis virus in massachusetts.eastern equine encephalitis (eee) virus is a highly pathogenic mosquito-borne zoonosis that is responsible for outbreaks of severe disease in humans and equines, resulting in high mortality or severe neurological impairment in most survivors. in the northeastern united states, eee virus is maintained in an enzootic cycle involving the ornithophilic mosquito, culiseta melanura (coquillett) and passerine birds in freshwater swamp habitats. to evaluate the role of cs. melanura and culiseta morsitan ...201323473221
efficacy of resmethrin aerosols applied from the road for suppressing culex vectors of west nile virus.we determined whether aerosol applications of resmethrin, delivered from the road, suppress the reproductive activity of culex pipiens pipiens and cx. restuans mosquitoes in suburban sites located near boston. oviposition implies a prior blood-feeding event and hence a potential west nile virus (wnv) transmission-related event. droplet size, rate of delivery and meteorological conditions were monitored. the target populations proved to be fully susceptible to the insecticide that was used. the r ...200616796509
update: west nile virus activity--eastern united states, reported to cdc through the west nile virus (wnv) surveillance system have shown an increase in the geographic range of wnv activity in 2000 compared with 1999, the first year that wnv was reported in the western hemisphere. in response to this occurrence of wnv, 17 states along the atlantic and gulf coasts, new york city, and the district of columbia conducted wnv surveillance, which included monitoring mosquitoes, sentinel chicken flocks, wild birds, and potentially susceptible mammals (e ...200011105767
density-equalizing euclidean minimum spanning trees for the detection of all disease cluster shapes.existing disease cluster detection methods cannot detect clusters of all shapes and sizes or identify highly irregular sets that overestimate the true extent of the cluster. we introduce a graph-theoretical method for detecting arbitrarily shaped clusters based on the euclidean minimum spanning tree of cartogram-transformed case locations, which overcomes these shortcomings. the method is illustrated by using several clusters, including historical data sets from west nile virus and inhalational ...200717519338

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 ...200818840738
