More Honey Bees Dying, Even as Antibiotic Use Halves
A new study led by University of Guelph researchers and funded in part by the Ontario Agri-Food Innovation Alliance is the first large-scale project to assess antibiotic usage trends and their impact on honey bee health in Canada.
The withdrawal of antibiotics, following recent regulation changes, was one of the top predictors of honey bee overwintering mortality — a result that surprised lead author Dr. Brendan Daisley.
