A widely used insecticide developed by Bayer AG and tied to deaths of honeybees isn’t the main cause of the fatalities, University of Maryland researchers said in a study that may weaken arguments used by environmentalists seeking to ban the chemical.
The insect-killer, imidacloprid, when applied at “realistic” levels doesn’t harm honeybee colonies, according to the three-year study published Wednesday in the peer-reviewed journal PLOS ONE.
