A low concentration of geosmin prevents recruitment into stinging behaviour by IAA. (a) Schematic of the behavioural assay. A dyad of bees was presented with a rotating dummy, that they could choose to sting or not. The red arrows denote the entry points of the airflow carrying the odours into the arena. (b) Frequency of trials in which at least one of the bees exhibited stinging behaviour (n = 48 dyads of bees per group). MO: mineral oil (solvent control); Geo 10−x: geosmin at concentration 10−x; IAA 10–1: isoamyl acetate at concentration 10–1. The groups labelled with the same letter are not significantly different from each other (GLM, corrected for multiple comparisons with an FDR procedure).
