Figure 2. Physiological dose-response curves of different bees for diacetin.
Electroantennographic responses (EAG) of oil bees (Macropis fulvipes/Rediviva neliana) and non-oil bees (Melitta haemorrhoidalis/Apis mellifera) to different dilutions of diacetin. SEM = standard error of the mean. Means (within the same species) that share same letters or do not have letters are not significantly different.
