mosquito trap

A woman in a green t-shirt, gray pants, and a blue ballcap checks a mosquito trap hanging from a tree branch in a wooded area. The mosquito trap is a cylindrical net with a larger section at the bottom and a wide flat metal plate at the top. Above the plate is a red water cooler housing dry ice to produce carbon dioxide to attract mosquitoes.

Effective mosquito control for preventing diseases like West Nile virus relies on gathering information on the viral infection status of mosquitoes in numerous areas. The Connecticut Agricultural Experiment Station runs such a viral surveillance program, which involves capturing and testing mosquitoes from 108 sites throughout the state. Here, a CAES researcher checks a mosquito trap at one of the surveillance sites. (Photo courtesy of Joseph R. McMillan, Ph.D.)
