Honeybees Impacted By Diesel Exhaust

In an attempt to understand the worldwide decline of honeybees, researchers from the University of Southampton found that diesel exhaust fumes change the chemical profile of floral aroma molecules which affect the honeybees’ ability to locate, identify and recognize a potential food source. In their study, they found that the nitric oxide and nitric dioxide components in exhaust were responsible for the molecular change. When these gases were present, the bees in the study were unable to locate flowers. Honeybees have a sensitive sense of smell and rely on learning and memorizing new odors, but diesel exhaust pollution keeps them from doing that. Researchers said that policy makers should work to improve air quality to save the honeybees.
