West Nile Virus in Montana

After mosquitoes were trapped and sent to the Veterinary Entomology Lab at Montana State University, the potential vector species were tested in pools of up to 50 mosquitoes. These pools were tested by the Montana Department of Public Health and Human Services, and by Carroll College's Department of Natural Sciences.
