Antenna movements as a function of odorants' biological value in honeybees (Apis mellifera L.).

Concerning antenna position (Δθ), we found a significant general effect of the stimulus (RM-ANOVA, F 2,82 = 3.45, p < 0.05), of the concentration (F 7,287 = 2.24, p < 0.05) and a highly significant interaction between both variables (F 14, 574 = 3.25, p < 0.001).

However, correlation coefficients between attractiveness indices and antenna movement variables were not significant (p = 0.12 for both angle and velocity), even if the figures suggest a possible trend, with attractive odorants corresponding more to fast and forward antenna movements.
