| effect of temperature on the development of culiseta melanura (diptera: culicidae) and its impact on the amplification of eastern equine encephalomyelitis virus in birds. | eastern equine encephalomyelitis virus (eee) is perpetuated in a maintenance cycle that involves culiseta melanura (coquillett) as the enzootic vector and passerine birds as the amplifying hosts. amplification of virus in any given year requires an influx of nulliparous cs. melanura in the presence of susceptible avian hosts. we conducted laboratory experiments at constant temperatures from 10 to 34 degrees c to develop thermal heat summation models to predict emergence in nature. embryonic deve ... | 1998 | 9835694 |
| eastern equine encephalomyelitis virus in relation to the avian community of a coastal cedar swamp. | eastern equine encephalomyelitis virus (eeev) is perpetuated in eastern north america in a mosquito-wild bird maintenance cycle that involves culiseta melanura (coquillett) as the principal enzootic vector and passerine birds as the primary amplifying hosts. we examined the role of birds in the eeev cycle at a site in southern new jersey where eeev cycles annually at high levels. birds and mosquitoes were sampled during three epiornitics and one season of limited virus activity. we examined anti ... | 1994 | 7966175 |
| isolation of eastern equine encephalitis virus from aedes sollicitans during an epizootic in southern new jersey. | eastern equine encephalitis virus (eee) was isolated from the salt marsh mosquito, aedes sollicitans, collected from coastal areas of new jersey on 3 occasions during the late summer and fall of 1982. the isolations were made at a time when local culiseta melanura were either undergoing a population increase or exhibiting high levels of eee virus. although no human cases were reported during the epizootic period, the data lend support to the hypothesis that ae. sollicitans is capable of function ... | 1986 | 2853203 |
| eastern equine encephalitis in quebec and connecticut, 1972: introduction by infected mosquitoes on the wind? | in 1972 there were outbreaks of eastern equine encephalitis in the eastern townships, quebec, canada and in connecticut, usa. climatic data including northern hemisphere synoptic charts were examined. the findings indicate that the virus could have been brought to lac brome by infected mosquitoes carried on surface winds from meriden, connecticut, on the night of august 22-23, 1972. the distance of 400 km would have been covered in 14-16 h at a speed of 25-30 km h-1 and at a temperature of 15 de ... | 1989 | 2563337 |
| trajectory analysis of winds and eastern equine encephalitis in usa, 1980-5. | backward trajectories of winds were determined to identify possible sources of eastern equine encephalitis virus associated with isolation of virus from mosquitoes or birds or outbreaks in horses between 1980 and 1985 in maryland, new jersey, new york and michigan, usa. the results of the trajectory analyses suggested that eastern equine encephalitis virus could have been carried by infected mosquitoes on surface winds at temperatures 13 degrees c or higher from north carolina north-eastwards al ... | 1990 | 1969804 |
