Table S4. Numbers of honeybee (Apis mellifera ) and bumblebee (Bombus spp.) individuals tested and positive forV. ceranae presence across six sites and two visits per site. We aimed to sample eight individuals per species per visit to each site where possible (target N = 16 per species per site), but there was some variation in the abundance of honeybees and bumblebees across visits to each field site.
