Figure 5
Comparative consumption of liquid food baits by colonies of Lasius niger black garden ants (n = 10) and Formica aserva thatching ants (n = 10). Colonies were offered a choice between aqueous solutions of essential amino acids [EAAs (5.55%) w/v], sucrose (5.55%, w/v), and both [EAAs (1%); sucrose (4.55%) w/v). Coloured symbols represent responses of individual colonies and black symbols are estimated marginal means and 95% confidence intervals. Treatment (bait composition) was a significant predictor of bait consumption (see results). Means with different letters are statistically different (p < 0.05) in pairwise comparisons (see Table S8).
