title: Isolation of Jamestown Canyon virus (California serogroup) from Aedes mosquitoes in an enzootic focus in Michigan.
abstract: Twenty isolates of Jamestown Canyon virus were obtained from adult females of 5 Aedes species collected at the Houghton Lake Wildlife Research Area, Missaukee County, in north-central Michigan between 1985 and 1989. Fourteen were from Aedes provocans, and 6 were from 4 other snowmelt Aedes species. One isolate of trivittatus virus and one Cache Valley-like virus were also obtained. Seasonal succession patterns for numerous mosquito species were recorded over 4 years. The temporal association of adult mosquito emergence, virus isolations, and infection and seroconversion of sentinel deer suggest that Ae. provocans is a primary enzootic vector of Jamestown Canyon virus in that focus. We hypothesize that Ae. provocans provides an overwintering reservoir for Jamestown Canyon virus at the study site. A large dry ice-baited "tent trap" was the most productive method for collecting numerous aedine and other mosquito species.
