Figure 2. Harnessed, antenna-intact forager honey bees can learn to respond differentially to color stimuli.
A, B. All forager honey bees completing visual training. C, D. Only those foragers that responded more than 3 cumulative times to light presentation prior the US (learners). A, C. The percentage of responses to light presentation on each trial. B, D. The average number of cumulative responses. Comparison of responses on trial 10 (A, C) used Chi-square test. Comparison of total cumulative responses (B, D) used Mann-Whitney U test. *p<0.005, **p<0.001, ***p<0.0001.
