Abstract
In tactile learning, sucrose is the unconditioned stimulus and reward,
which is usually applied to the antenna to elicit proboscis extension and
which the bee can drink when it is subsequently applied to the extended
proboscis. The conditioned stimulus is a tactile object that the bee can scan
with its antennae. In this paper we describe the quantitative relationships
between gustatory antennal stimulation, gustatory proboscis stimulation, and
tactile learning and memory. Bees are 10-fold more responsive to sucrose
solutions when they are applied to the antenna compared to proboscis
stimulation. During tactile conditioning, the sucrose solution applied to the
proboscis determines the level of acquisition, whereas antennal input is of
minor importance. Bees differing in their gustatory responsiveness measured at
the antenna differ strongly in their tactile acquisition and memory. We
demonstrate how these differences in tactile acquisition and memory can be
greatly reduced by calculating equal subjective rewards, based on individual
gustatory responsiveness.
