Three A. c. cerana colonies are shown by parentheses following the apiary names. The rest of 17 samples are A. m. ligustica colonies. DW in parenthesis indicates that pathogens and parasites are specifically detected with dying worker bees (workers crawling on the ground).+ and - indicate positive and negative detections, respectively.
