Honeybees usually learn floral scents quickly, but it’s harder for them when the fragrance of roadside flowers mixes with car exhaust. In lab tests, bees normally caught on quickly that a puff of floral scent meant a researcher would soon offer them a taste of sugar, Ryan James Leonard of the University of Sydney said September 30 at the International Congress of Entomology. After two sequences of puff-then-sugar, just a whiff of fragrance typically made the bees stick out their tongues. Road ecologists have put a lot of effort into studying how vehicles kill animals. http://bit.ly/2dBFweO http://bit.ly/1fJ5yqZ This video was produced by YT Wochit News using http://wochit.com
