Discrimination of Complex Odour Mixtures: PER Response [%].

Table shows PER response in % to the training and test mixtures (N = 27 bees for each trial). Numbers in brackets signify number of key odorants in training mixtures, and numbers of odorants in the test mixture that are also key odorants of the training mixture. *: Significant difference in PER response between testing mixture and training mixture (grey boxes), McNemar Chi square test [2×2 Table], p<0.05. For mixture composition see Table 2.
