Fig. 6. Results of Experiment 3. Bees were trained without a landmark and tested
with a landmark. (A) Bees tested without the landmark searched broadly in the
tunnel. (B-D) Bees tested with the landmark (B) at the training site, (C)
shifted to unit 14, and (D) shifted to unit 4, all tended to make first turns
before reaching the landmark. This effect suggests that bees are repelled by
the novel landmark placed along a familiar path. For an explanation of figure
layout and symbols, see Fig.
