Abstract

During the summer of 1964 and the spring and summer of 1965, California encephalitis group viruses were isolated from six pools of boreal mosquitoes collected in and near Rochester (54°N, 113°W), Alberta, Canada. Mosquitoes were collected by aspiration, by sweep-netting, and with a CO-baited cone trap. Collections were placed on Dry Ice and shipped to Madison, Wisconsin, for identification and isolation of virus. mosquitoes accounted for 97% of 16,453 mosquitoes examined for virus. Snowshoe hare virus of the California group was isolated from three pools of group, and one pool of group. Jamestown Canyon virus of the California group was isolated from one pool of and from a pool of spp. The minimum vector-infection rate was 0.40 isolates per 1,000 spp. mosquitoes in 1964, 0.46 isolates per 1,000 group mosquitoes in 1965, and 0.33 isolates per 1,000 group mosquitoes in 1965.
