Mean (±s.e.m.) (A) total consumption (g), controlled for evaporation of solutions at lowest concentration (0.001 mmol l⁻¹) for each nectar toxin, and (B) mortality of Bombus terrestris fed five different nectar toxins. Control bumblebees were fed 0.5 mol l⁻¹ sucrose in both solutions and so had no exposure to any toxin. N=40 bees per toxin per concentration. Different lowercase letters represent significant (P<0.05) differences in total consumption between compounds according to LSD post hoc comparison.
