Resumen
Information exchange of environmental cues facilitates decision-making processes among members of insect societies. In honeybee foraging, it is unknown how the odor cues of a resource are relayed to inactive nest mates to enable resource exploitation at specific scented sources. It is presumed that bees need to follow the dance or to be involved in trophallaxis with a successful forager to obtain the discovered floral scent. With this in mind, we evaluated the influence of food scent relayed through in-hive interactions and the subsequent food choices. Results obtained from five colonies demonstrated that bees arriving at a feeding area preferred to land at a feeder carrying the odor currently exploited by the trained forager. The bees that landed at this feeder also showed more in-hive encounters with the trained forager than the individuals that landed at the alternative scented feeder. The most frequent interactions before landing at the correct feeder were body contacts with the active forager, a behavior that involves neither dance following nor trophallaxis. In addition, a reasonable proportion of successful newcomers showed no conspicuous interactions with the active forager. Results suggest that different sources of information can be integrated inside the hive to establish an odor-rewarded association useful to direct honeybees to a feeding site. For example, simple contacts with foragers or food exchanges with non-active foragers seem to be enough to choose a feeding site that carries the same scent collected by the focal forager.
