Body size variation of Culiseta morsitans in relation to vector potential for eastern equine encephalomyelitis virus.
نویسندگان
چکیده
Variation in the body size of wild Culiseta morsitans collected from Massachusetts was examined. No significant size variation was detected at any time during the collection period, nor was there a significant size difference between parous and nulliparous mosquitoes. We conclude that size variation in this species does not affect survivorship, an important aspect of vectorial capacity.

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 ...
متن کاملVector-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 p...

From June through August in 1999 and 2000, we conducted an avian serosurvey for eastern equine encephalomyelitis (EEE) virus at Killbuck Marsh Wildlife Area (KMWA), a focus of infection in central Ohio. We also monitored abundance of the suspected enzootic vector, Culiseta melanura Coquillett, in Brown's Lake Bog, an adjacent wetland. Of the 363 birds of 30 species sampled in 1999, three gray c...
متن کاملReduction of Culiseta melanura fitness by eastern equine encephalomyelitis virus.
The traditional view of interactions between arboviruses and their arthropod vectors is that vector hosts become increasingly resistant to parasites; parasite attenuation occurs; or through the process of coevolution, resistance and attenuation occur in concert. Detrimental effects from arboviruses are only seen when vector and virus are not yet well adapted. Results from this study indicate th...

The relationship between body size and parity status of adult female Culiseta melanura collected from 3 locations in northeastern United States was studied by measuring wing lengths and examining ovaries of individual mosquitoes. Virus isolation was attempted from Cs. melanura collected in Maryland and in New Jersey. At all 3 locations, the size of Cs. melanura collected varied from large in th...
