Effects of bioactive food compounds on honey bee survival. (A) Overview of all substances studied and the selected concentrations used in the feed. Upward pointing arrow signifies increased life span, rectangular box, no statistical effect on life span, downward pointing arrow signifies shorter life span (p < 0.05 Pair-wise Log-Rank test corrected using FDR). (B) Kaplan–Meier plot of survival curves of ethanol (1% (v/v)) alone and in combination with curcumin at 1, 10 and 100 µg/ml. Pluss signs indicate censored honey bees. Asterisks in legends indicates significant effects on survival compared to controls.
