Nowadays we can find a number of experiments that have showed the importance of learning in several situations related with survival of many animal species. For instance, knowledge acquired in the early stages of life could be crucial on the choice of egg-laying site. In this study we explored the influence of Pavlovian conditioning of silkworm larvae on their oviposition behaviour as adult female moths. For this, the larvae learning have to survive the metamorphosis and be shown in oviposition choice. In acquisition phase, a larvae group experienced an odour (conditioned stimulus) paired with mulberry leaves (unconditioned stimulus), another one experienced the odour and the mulberry leaves in an unpaired way and the last one experienced the odour alone during this phase. The results show that when these larvae became moths, only the first group preferred to lay their eggs near the odour when it was present during the test, so that associations learned during the larval stage seem to influence oviposition behaviour during adulthood.
如今，我们可以找到许多实验，这些实验表明了学习在与许多动物物种生存相关的多种情况下的重要性。例如，在生命早期阶段获得的知识可能对产卵地点的选择至关重要。在本研究中，我们探讨了家蚕幼虫的巴甫洛夫条件反射对其成年雌蛾产卵行为的影响。为此，幼虫学习必须在变态过程中存活下来，并在产卵选择中表现出来。在习得阶段，一组幼虫经历了一种气味（条件刺激）与桑叶（非条件刺激）配对，另一组幼虫以非配对的方式经历了这种气味和桑叶，最后一组幼虫在此阶段仅经历了这种气味。结果表明，当这些幼虫变成蛾子后，只有第一组在测试期间有气味时更喜欢在气味附近产卵，因此幼虫阶段学到的关联似乎会影响成年期的产卵行为。
