| relative importance of bird species as hosts for immature ixodes dammini (acari: ixodidae) in a suburban residential landscape of southern new york state. | abundance of birds and their tick parasites were estimated in a residential community located in westchester county, ny, where lyme disease is endemic. in total, 36 bird species (416 captures) were collected, of which 25 species (69%) were parasitized by ticks. ixodes dammini spielman, clifford, piesman & corwin composed 96.4% of the 1,067 ticks found on birds. the bird species most heavily parasitized was house wren, troglodytes aedon vieillot (11.1 ixodes dammini per bird). relative density es ... | 1993 | 8360897 |
| host-feeding habits of culex and other mosquitoes (diptera: culicidae) in the borough of queens in new york city, with characters and techniques for identification of culex mosquitoes. | the host-feeding patterns of mosquitoes (n = 247) collected in the borough of queens in new york city in july and august 2000 were investigated using an indirect elisa and a polymerase chain reaction (pcr)-heteroduplex assay. culex pipiens l. and cx. restuans theobald fed primarily on birds, and their feeding habits support their implication as enzootic vectors of west nile virus. culex salinarius coquillett and coquillettidia perturbans (walker) fed mainly on mammals, with fewer blood meals tak ... | 2002 | 12349862 |
| host feeding patterns of established and potential mosquito vectors of west nile virus in the eastern united states. | an important variable in determining the vectorial capacity of mosquito species for arthropod-borne infections is the degree of contact of the vector and the vertebrate reservoir. this parameter can be estimated by examining the host-feeding habits of vectors. serological and polymerase chain reaction based methods have been used to study the host-feedings patterns of 21 mosquito species from new york, new jersey, and tennessee, 19 of which previously have been found infected with west nile viru ... | 2004 | 15018775 |
| vectest as diagnostic and surveillance tool for west nile virus in dead birds. | the vectest antigen-capture assay for west nile virus was performed on oral and tissue swabs from dead birds in new york state from april 2003 through july 2004. results were compared with those from real-time reverse transcriptase-polymerase chain reaction of kidney or brain. oral vectest sensitivity is adequate for surveillance in american crows (corvus brachyrhynchos) (87%), blue jays (cyanocitta cristata) (80%), and house sparrows (passer domesticus) (76%). oral vectest performed well for sm ... | 2004 | 15663856 |
| molecular identification of blood-meal sources in culiseta melanura and culiseta morsitans from an endemic focus of eastern equine encephalitis virus in new york. | eastern equine encephalitis (eee) virus perpetuates in an enzootic cycle involving ornithophilic mosquito vectors, principally culiseta melanura (coquillett) and avian amplification hosts. to better understand the role of cs. melanura and culiseta morsitans (theobald) in the epizootiology of eee virus, we collected blood-fed mosquitoes between 31 may and 15 october 2004 at two sites associated with an eee virus focus in central new york and identified the source of vertebrate blood by nucleotide ... | 2006 | 17172382 |
