Vector Potential of Selected North American Mosquito Species for Rift Valley Fever Virsus
Abstract
Selected North American mosquito species were evaluated as potential vectors of Rift Valley virus. Field populations of Aedes canadensis, Ae. cantator, Ae. excrucians, ae. sollicitans, ae. taeniorhynchus, Ae. triseriatus, Anopheles bradleyi-crucians, Culex salinarius, Cx. tarsalis, and Cx. territans perorally exposed to plaque forming units of Rift Valley fever virus readily became infected. Infection rates ranged from 51% (65/127) for Cx. salinarius to 96% (64/67) for Ae. canadensis. For most of the species, about half of the mosquitoes with a disseminated infection transmitted an infectious dose of virus to hamsters. These data suggest that, if Rift Valley fever virus was introduced into North America, several mosquito species would be capable of transmitting it.
