Brandon Kingsley Hopkins, Ph.D., assistant research professor at Washington State University and apiary and laboratory manager at the WSU Apiary Program, co-authored a new study published in May in the Journal of Economic Entomology that shows storing honey bee colonies with elevated levels of carbon dioxide reduces levels of Varroa mites, a method that might prove useful in reducing beekeepers’ winter colony losses.
