ABSTRACT
Olfactory learning in the honeybee was investigated using the conditioned proboscis extension reflex on restrained individuals. We compared, under the same experimental conditions, the most commonly used conditioning procedures, i.e. 1 trial, 3 massed trials (1 min inter-trial intervals), and 3 spaced trials (10 min inter-trial intervals) procedures, using linalool as the conditioned stimulus. Two experiments were performed in which worker bees were subjected to (1) a single test at different times (30 s to 14 days) after the conditioning procedure; (2) a first test within 3 h after the conditioning procedure, and were then retested daily (up to 5 tests). The memory trace of a learnt odorant stimulus could last for the lifetime of the bee, even after a single association with sugar. Repeated tests with 1 day inter-test duration induced a strong decrease of the response level, this effect being more pronounced after a 1-trial conditioning.
