Honeybees learn odor cues quickly and efficiently when visiting rewarding flowers. Memorization of these cues facilitates
the localization and recognition of food sources during foraging flights. Bees can also use information gained inside the
hive during social interactions with successful foragers. An important information cue that can be learned during these interactions
is food odor. However, little is known about how floral odors learned in the hive affect later decisions of foragers in the
field. We studied the effect of food scent on foraging preferences when this learning is acquired directly inside the hive.
By using in-hive feeders that were removed 24 h before the test, we showed that foragers use the odor information acquired
during a 3-day stimulation period with a scented solution during a food-choice situation outside the nest. This bias in food
preference is maintained even 24 h after the replacement of all the hive combs. Thus, without being previously collected outside
by foragers, food odors learned within the hive can be used during short-range foraging flights. Moreover, correct landings
at a dual-choice device after replacing the storing combs suggests that long-term memories formed within the colony can be
retrieved while bees search for food in the field. 相似文献

Honeybees ingested 50% w/w (1.8 M) sucrose solution at a rate feeder offering either 16.5, 32.5 or 65 μl/min. While the time
spent ingesting solution at the feeder decreased significantly with increasing flow of solution, bees attained maximum crop
loads with this range of flows. Different parameters related to mouth-to-mouth food exchange (trophallaxis) showed important
modulations as the offered flow of solution was incremented. Trophallactic transfer rate, i.e. the speed at which liquid food
is transferred from donor to recipient bee, was found to increase along with increasing profitability at the rate feeder.
In the present case, food source profitability could have been evaluated by foragers either by measuring the time invested
in ingesting the solution, or by direct assessment of the flow rate of the feeder. Thus it seems that perception of profitability
conditions at the food sourcesuffices for later representation in the hive through trophallactic contacts, independently of
crop-filling state.
