Navigation in honeybees: the organization of large-scale spatial memory


Harmonic radar tracking was used in summer 2012 to record the flights of scout bees during take-off and the initial flight path of a honeybee swarm. One swarm performed a full flight to a destination beyond the range of the harmonic radar, another swarm disintegrated within the range of the radar and most of the bees returned to the queen, which had remained at the starting point. We found that the initial stretch of the full flight is characterized by accelerating speed, whereas the disintegrating swarm flew steadily at low speed. The two scouts in the swarm displaying full flight performed characteristic flight maneuvers. They flew at high speed when traveling in the direction of their destination, and slowed down or returned over short stretches at low speed. Scouts in the disintegrating swarm did not exhibit this characteristic flight performance. Our data support the streaker bee hypothesis proposing that scout bees guide the swarm by traveling at high speed in the direction of the new nest site for short stretches of flight and slowing down when reversing flight direction.

Sleep and its role in memory consolidation

The role of sleep in the honeybee memory consolidation has been addressed in our lab in two studies so far. Hussaini et al. (2009; Deprivation.pdf)  found reduced retention after extinction learning in an olfactory PER experiment if bees are prevented from sleep during the night following extinction learning. Beyaert, Greggers and Menzel tested freely flying bees after navigation learning and found reduced homing rates if the bees could not sleep the night after novel navigation learning (see Beyaert L, Greggers U and Menzel R (2012) Honeybees consolidate navigation memory during sleep. Journal of Experimental Biology 215, 3981-3988) These results support the hypothesis that specific forms of memory consolidation are affected by sleep because acquisition learning in the olfactory PER experiment and cue learning in the free flying bee experiment were not compromised after sleep deprivation. We are currently performing experiments that aim to test whether memory consolidation can be facilitated during sleep phases. We also analyze a large data set from long term extracellular multi unit recordings searching for neural activity patterns during sleep phases (Ina Klinke). Furthermore, we carry out laboratory based navigation experiments and interfere with sleep deprivation (Nanxiang Jin).
