Gustatory responsiveness of free-flying bees after exposure to scented sucrose solution.

<p>GRSs of hive bees belonging to different age groups: 6/9 days old (<b>A</b>), 12/16 days old (<b>B</b>) and foragers (<b>C</b>) were measured. Bees were captured either while being offered an unscented sucrose solution (15% w/w) (0 hours) or after 8 h and 24 h of foraging from a scented sucrose solution (LIO, 15% w/w). The asterisks indicate statistical differences in a Kruskal-Wallis test and Dunn comparison (* p<0.05, ** p<0.001, n.s. not significant; for details see the text). The number of observations is shown in parentheses. Boxes indicate the inter-quartile range, horizontal lines within boxes indicate the medians, whiskers include all points within 1.5 times the inter-quartiles, empty circles indicate outliers.
