Abstract:
Nosema apis inoculated and non-inoculated honeybee (Apis mellifera) queens were introduced
into mating nuclei. The workers accepted all queens from both groups. During the 26 days of the
experiment, 47.4% of the inoculated and 50% of the non-inoculated queens were lost. Queens from both
groups started egg-laying after 15.8 days. Workers did not perceive the presence of N. apis in their
queens and did not supersede inoculated queens significantly more often than healthy ones. Significantly
more workers were infected in the mating nuclei with inoculated queens (61%) than in those with
non-inoculated ones (5.3%).
