Figure 3: The impaired response to IAA was not caused by masking of this pheromone by the floral compounds.
From: Appetitive floral odours prevent aggression in honeybees
‘CS=IAA’: bees trained to associate a reward with IAA also responded well when IAA was mixed with the plant odour but less to the untrained plant odour alone. ‘CS=IAA+Odourant’: bees trained with the mixture also responded to IAA and the plant odour when they were presented alone. However, in the case of Pr they also generalized to the novel plant odour β-c. ‘CS=Odourant’: bees trained to the plant odour did not respond well when this odourant was mixed with IAA or when IAA alone was presented. Again, in the case of Pr they generalized to the novel plant odour β-c. McNemar tests, Bonferroni-corrected threshold α; NS, not significant; P>α, *P<α, n=53–56 bees per conditioned group.
