Fly attractant research. Entomologist checking stable flies (Stomoxys calcitrans) caught on a trap baited with a newly designed attractant, or lure, in a cattle feeding station. Attractants on traps such as these are developed to help control the number of potentially disease-carrying flying insects on farms. Photographed on the research farm at the University of Nebraska, USA. | |
