Abstract

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— and —were most prevalent during the wet season when transmission normally occurs. However, only yielded VEE virus. The bloodfeeding patterns of these species revealed that and fed almost exclusively on bovine and equine hosts. Conversely, was highly ornithophilic but occasionally fed on mammals. exhibited a wide host range, utilizing both large and small mammals as well as birds and, rarely, reptiles. The versatility in feeding pattern displayed by this mosquito coupled with its ability to become infected with relatively low levels of enzootic VEE virus suggests that vertebrates other than rodents may serve as amplifying hosts in this habitat.

Nepuyo virus was also isolated from , suggesting that this mosquito might be an endemic vector of this rodent-associated bunyavirus. A single isolate of St. Louis encephalitis virus was made from .
