Group feeding resulted in significantly higher whole-body imidacloprid residues compared to the individually fed honeybees. Individual honeybees were fed with a single dosage of 41 ng/bee (RT1, RT24, RT48). Alternatively, groups of ten honeybees per cage were fed with 410 ng/cage imidacloprid (RT24GF). One dot indicates imidacloprid value of one sample of ten bees. Five samples of each hive are presented in one column (n = 150 bees/group). Statistical comparison with an ANOVA yielded a significant effect of the applied treatment (p < 0.001) and multiple comparisons using Dunnett contrasts resulted in RT1 vs. RT24GF: p = 0.0128; RT24 vs. RT 24GF: p < 0.001; RT48 vs. RT24GF: p < 0.001 (see statistical report in supplement).
