Abstract
Successful bidirectional selection for discriminative olfactory learni ng is reported for drone honey bees (Apis mellifera). Learning perform ance was evaluated using a discrimination conditioning procedure that required drones to discriminate between an appetitively reinforced odo rant and one that was followed by punishment, Selective breeding produ ced high - and low - learning-performance lines of worker progeny that diverged from performance of workers whose fathers were selected at r andom. Furthermore, we show that levels of sucrose-induced sensitizati on are not correlated to learning performance. These results corrobora te earlier findings and further demonstrate the power of selection on a haploid (drone) genotype, In addition, this study now shows that the demonstrated differences in learning performance cannot be completely accounted for by alteration of sucrose-induced sensitization. Thus, u sing this technique, it may be possible to select for associative cond itioning without a pleiotropic increase in sensitization, The honey be e will be ideally suited to these types of correlation analyses in fut ure studies.
