Patch Departure Behavior of Bumble Bees: Rules and Mechanisms

Table 9

Departure patterns of bumble bees on treated inflorescences of Aconitum columbianum. The experiment used a descending series of volumes of 30% sucrose solution, from 6 to 0 microliters, in bottom flowers of the inflorescence, with second-from-bottom and third-from-bottom flowers empty. The notation for visit patterns is as detailed in Table 8. Three-way log-likelihood test of independence, G = 28.085, $P<.01$ for the 3-way interaction.
