A US presentation alone does not account for the enhanced odor response 24 h after backward conditioning. (A) Schematic overview of the experiment. Honeybees were either treated with three backward conditioning trials (BW), exposed to three US trials (US), or were left untreated (Naive). (B) Twenty-four hours later the PER was tested with a CS (clove oil) presentation in all groups (BW, black; US, gray; Naive, white). Bars with unequal letters (a–c) differ significantly (P < 0.01).
