| entomological studies at an enzootic venezuelan equine encephalitis virus focus in guatemala, 1977-1980. | the ecology of several potential mosquito vectors of venezuelan equine encephalitis (vee) alphavirus was studied in an enzootic focus of that virus on the pacific coast of guatemala over a four-year period. four species-culex taeniopus, mansonia titillans, culex nigripalpus and aedes taeniorhynchus-were most prevalent during the wet season when transmission normally occurs. however, only cx. taeniopus yielded vee virus. the bloodfeeding patterns of these species revealed that ae. taeniorhynchus ... | 1986 | 2873752 |
| vector competence of three venezuelan mosquitoes (diptera: culicidae) for an epizootic ic strain of venezuelan equine encephalitis virus. | experimental studies were undertaken to evaluate the vector competence of selected mosquito species [aedes taeniorhynchus (wiedemann), culex declarator dyar and knab, and mansonia titillans (walker)] from northwestern venezuela for the epizootic (ic) strain of venezuelan equine encephalitis (vee) virus that was responsible for the 1995 outbreak of vee in this area. ae. taeniorhynchus was highly susceptible to infection (94% of 35), and 89% had a disseminated infection. virus-exposed ae. taeniorh ... | 1999 | 10467764 |
| spatial dispersion of adult mosquitoes (diptera: culicidae) in a sylvatic focus of venezuelan equine encephalitis virus. | we studied the spatial localization of mosquitoes in sylvatic focus of venezuelan equine encephalitis virus in western venezuela to identify mosquito species potentially involved in the hypothesized transport of viruses out of enzootic foci. the following criteria were used to identify species with potential for virus export: (1) common in the forest and surrounding area, (2) feeding on a wide range of vertebrates; (3) long dispersal capabilities, and (4) established vectorial competence for enz ... | 2001 | 11761379 |
| ecological characterization of the aquatic habitats of mosquitoes (diptera: culicidae) in enzootic foci of venezuelan equine encephalitis virus in western venezuela. | we studied the aquatic mosquito habitats in and around enzootic foci of venezuelan equine encephalitis virus (vee) in western venezuela. specimens were sampled for 5 mo in three types of vegetation: tall lowland tropical forests, short inundated/secondary growth forests, and pastures/herbaceous vegetation around forests. ground pools, flooded pastures, swamps, ponds, and canals predominated. we used a multivariate statistical approach to quantitatively assess the relationships of mosquito specie ... | 2005 | 15962775 |
