Table I

Average values for the proportion of tagged bees, visits/bee, visit duration, total time, and average time the bees in the H and NH colonies spent inspecting, uncapping and removing the chalkbrood mummies from the cells (n = 2100). Proportions followed by different letters show significant differences between the lines of bees for the variable measured.
