Fig. 6. Experiment 3. Scent-triggered navigation in individual bees, trained alternately to two feeders, each placed in a different location and carrying a different scent. The figure shows the results of experiments using the following scent combinations: rose and lemon, rose and almond, and almond and lemon. Pie charts show distribution of visits to the two test feeders in each experiment, when the respective scents were blown into the hive (white, former rose feeder; light grey, former lemon feeder; dark grey, former almond feeder). In each experiment data are accumulated from four tests for each scent, and are shown separately for first visits, circlings, landings and total visits. The number of individually marked bees that visited both test feeders, the number of choices (N) and P-values for tests of significant difference between the two feeders when the respective scents were blown (Chi² test) are shown below the pie charts.
