| dirofilaria immitis and its potential mosquito vectors in central new york state. | screening of 25,822 dog blood samples indicated approximately a 1% infection rate with dirofilaria immitis. dipetalonema reconditum microfilariae were found in approximately 2% of 1,876 feral dogs examined. laboratory experimentation indicated that 6 of 10 local mosquito species examined allowed successful extrinsic incubation of d immitis. indices of experimental infection indicated aedes triseriatus and anopheles quadrimaculatus were excellent hosts for d immitis, but other factors considered, ... | 1977 | 20828 |
| west nile virus infection in mosquitoes, birds, horses, and humans, staten island, new york, 2000. | west nile (wn) virus transmission in the united states during 2000 was most intense on staten island, new york, where 10 neurologic illnesses among humans and 2 among horses occurred. wn virus was isolated from aedes vexans, culex pipiens, cx. salinarius, ochlerotatus triseriatus, and psorophora ferox, and wn viral rna was detected in anopheles punctipennis. an elevated weekly minimum infection rate (mir) for cx. pipiens and increased dead bird density were present for 2 weeks before the first h ... | 2001 | 11589172 |
| the importance of agricultural tire habitats for mosquitoes of public health importance in new york state. | the presence of mosquito species breeding in agricultural "bunker tires" on dairy farms in new york state was evaluated. twelve species of mosquitoes (aedes vexans, anopheles barberi, an. punctipenriis, an. perplexens, culex pipiens pipiens, cx. restuans, cx. salinarius, cx. territans, toxorhynchites rutilus septentrionalis, ochlerotatus atropalpus, oc. japonicus japonicus, and oc. triseriatus) were collected from 8 new york state dairy farms in 2001 and from 17 dairy farms in 2002. all but 2 of ... | 2005 | 16033118 |
| comparative analysis of distribution and abundance of west nile and eastern equine encephalomyelitis virus vectors in suffolk county, new york, using human population density and land use/cover data. | five years of cdc light trap data from suffolk county, ny, were analyzed to compare the applicability of human population density (hpd) and land use/cover (luc) classification systems to describe mosquito abundance and to determine whether certain mosquito species of medical importance tend to be more common in urban (defined by hpd) or residential (defined by luc) areas. eleven study sites were categorized as urban or rural using u.s. census bureau data and by luc types using geographic informa ... | 2008 | 18533453 |
| identification of environmental covariates of west nile virus vector mosquito population abundance. | the rapid spread of west nile virus (wnv) in north america is a major public health concern. culex pipiens-restuans is the principle mosquito vector of wnv in the northeastern united states while aedes vexans is an important bridge vector of the virus in this region. vector mosquito abundance is directly dependent on physical environmental factors that provide mosquito habitats. the objective of this research is to determine landscape elements that explain the population abundance and distributi ... | 2010 | 20482343 |
| meteorologically conditioned time-series predictions of west nile virus vector mosquitoes. | an empirical model to forecast west nile virus mosquito vector populations is developed using time series analysis techniques. specifically, multivariate seasonal autoregressive integrated moving average (sarima) models were developed for aedes vexans and the combined group of culex pipiens and culex restuans in erie county, new york. weekly mosquito collections data were obtained for the four mosquito seasons from 2002 to 2005 from the erie county department of health, vector and pest control p ... | 2008 | 18279008 |
| vector competence of north american mosquitoes (diptera: culicidae) for west nile virus. | we evaluated the potential for several north american mosquito species to transmit the newly introduced west nile (wn) virus. mosquitoes collected in the new york city metropolitan area during the recent wn virus outbreak, at the assateague island wildlife refuge, va, or from established colonies were allowed to feed on chickens infected with wn virus isolated from a crow that died during the 1999 outbreak. these mosquitoes were tested approximately 2 wk later to determine infection, disseminati ... | 2001 | 11296813 |
| potential for new york mosquitoes to transmit west nile virus. | we evaluated the potential for several north american mosquito species to transmit the newly introduced west nile (wn) virus. mosquitoes collected in the new york city metropolitan area during the recent (1999) wn outbreak were allowed to feed on chickens infected with wn virus isolated from a crow that had died during this outbreak. these mosquitoes were tested approximately 2 weeks later to determine infection, dissemination, and transmission rates. culex pipiens mosquitoes were highly suscept ... | 2000 | 11037788 |
