Figure 3.

Effect of a chronic feeding of LiCl (10 mM, 17.5 mM and 25 mM) in free flying colonies on the survival of the honey bee brood starting on the BFD (brood area fixing day) till BFD + 16 compared to the untreated control (n = 3). The total number of selected eggs on BFD were 797 (control), 748 (10 mM), 741 (17.5 mM) and 748 (25 mM). The 25 mM treatment elicited high brood mortalities; however, there were no significant differences between the treatment groups (p = 0.516, p = 0.123, Kruskal–Wallis test).
