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.

Preimaginal 条件影响蚕蛾 (Bombyx mori) 的产卵选择

如今，我们可以找到许多实验，这些实验表明在与许多动物物种的生存相关的几种情况下学习的重要性。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。在这项研究中，我们探讨了蚕幼虫的巴甫洛夫条件对它们作为成年雌蛾的产卵行为的影响。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显示出来。在获得阶段，一个幼虫组体验到一种气味（条件刺激）与桑叶（非条件刺激）配对，另一个幼虫以不成对的方式体验到气味和桑叶，最后一个在这个阶段单独体验到气味。结果表明，当这些幼虫变成飞蛾时，
