The Influence of Gustatory and Olfactory Experiences on Responsiveness to Reward in the Honeybee
Figure 4
Gustatory responsiveness after withdrawl of scented sucrose solution.
Gustatory response score (GRS) of caged bees that were exposed during their whole adult lifespan (15 days) to a constant reward program of unscented 15% w/w sucrose solution (A). (B) GRSs of bees that were fed until 14 days of age with an unscented solution, then fed scented sucrose (LIO, 15% w/w) for 24 hours, and then again on unscented sucrose for the following 24 hours (i.e. 15th day). Asterisks indicate statistical differences (Kruskal-Wallis test, * p< 0.05, ** p<0.01, 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.
