Effect of kiwifruit mimic odor and nectar nonsugar compounds on the amount of stored pollen in honey bee colonies. Colonies were stimulated with kiwifruit mimic scented sucrose solution (KM) or KM-scented sucrose solution containing individually nectar non-sugar compounds, caffeine or l-arginine, or combined (KM + CAF, KM + ARG, KM + MIX). The total pollen area of beehives was assessed the day before applying the treatments and 8 days afterwards. Boxplots show the median and interquartile range (IQR), with whiskers showing the maximum value within 1.5 IQR, and individual points mark values outside this range. Letters indicates significant differences between treatments obtained by performing post-hoc comparisons (Table S2).
