Social Learning in Bumblebees (Bombus impatiens): Worker Bumblebees Learn to Manipulate and Forage at Artificial Flowers by Observation and Communication within the Colony
Figure 3
The learning curve (time/sec) (±SE) taken to access and forage on syrup for 10 initially naive workers of Bombus impatiens which were allowed to forage freely, but only one at a time, at artificial flowers with and without dead bees present. After the bees had demonstrated their ability to forage at the flowers with dead bees present (i.e., after 3 trails), those flowers were replaced with cleaned ones without dead bees present. The activities of the foragers were recorded for a further 7 visits. H0 showing that the durations for successful foraging are independent of experience is rejected (; ).
