mosquito and arbovirus activity during 1997-2002 in a wetland in northeastern mississippi.the species composition and population dynamics of adult mosquitoes in a wetland near iuka, ms, were analyzed over a 6-yr period (1997-2002) and reverse transcription-polymerase chain reaction (pcr) detection rates of arboviruses determined during five of those years. blood meals of three likely vector species were identified using a pcr-based method that allows identification of the host to species. culex erraticus (dyar & knab) composed 51.9% of the population during the 6-yr period with 295 f ...200415185956
host-feeding patterns of suspected west nile virus mosquito vectors in delaware, 2001-2002.paucity of data on host-feeding patterns and behavior of 43 mosquito species that are reported as suspected west nile virus (wn) vectors has limited full evaluation of their vectorial capacity. recent studies addressing this issue need additional confirmation and should also be expanded to include collections of species or subpopulations attracted to humans. we used 4 types of collection methods to collect mosquitoes, including omnidirectional fay-prince traps, centers for disease control-type l ...200516033122
detection of west nile virus rna in mosquitoes and identification of mosquito blood meals collected at alligator farms in louisiana.since 2001, alligator farms in the united states have sustained substantial economic losses because of west nile virus (wnv) outbreaks in american alligators (alligator mississippiensis). once an initial infection is introduced into captive alligators, wnv can spread among animals by contaminative transmission. some outbreaks have been linked to feeding on infected meat or the introduction of infected hatchlings, but the initial source of wnv infection has been uncertain in other outbreaks. we c ...201020695278
host choice and west nile virus infection rates in blood-fed mosquitoes, including members of the culex pipiens complex, from memphis and shelby county, tennessee, 2002-2003.the source of bloodmeals in 2,082 blood-fed mosquitoes collected from february 2002 through december 2003 in memphis and surrounding areas of shelby county, tennessee were determined. members of the genus culex and anopheles quadrimaculatus predominated in the collections. members of the cx. pipiens complex and cx. restuans were found to feed predominately upon avian hosts, though mammalian hosts made up a substantial proportion of the bloodmeals in these species. no significant difference was s ...200717767413
mosquitoes in moose country: a mosquito survey of northern minnesota.an adult mosquito survey was conducted at 12 sites using carbon dioxide traps in northern minnesota throughout the summer of 2012. specimens were counted, identified to species, sorted into pools, and tested for eastern equine encephalitis (eeev) and west nile virus (wnv). our findings extend the known range of culiseta melanura, anopheles barberi, and an. quadrimaculatus and document the presence and abundance of 27 other mosquito taxa in the region. none of the pools tested positive for eeev o ...201627280346
