Adult worker honey bees spend less time sleeping inside cells as
they age and change caste, but foragers slept considerably more
inside cells during this study than previously documented (1)
(treatment bees, 8.4% ± 4.4%; control bees, 9.3% ± 4.6% of
total observations, averaging measures per bee). Treatment bees
slept less inside cells during the night after sleep deprivation
compared with control bees (5.7% ± 3.0% vs. 21.7% ± 8.0% of
observations) relative to the night after DD (z = −3.21; P =
0.0090) and relative to the night before sleep deprivation, although
this latter comparison was not statistically significant (z =
−2.22; P = 0.1400). At present, how much deep sleep is obtained
inside cells, and how sleep inside cells specifically contributes to
recovery sleep, remain unclear.
