Plant volatiles are important cues for many herbivorous insects when choosing a suitable host plant and finding a mating partner. An appropriate behavioural response to sensory cues from plants and other insects is crucial for survival and fitness. As the natural environment can show both large spatial and temporal variability, herbivores may need to show behavioural plasticity to the available cues. By using earlier experiences, insects can adapt to local variation of resources. Experience is well known to affect sensory-guided behaviour in parasitoids and social insects, but there is also increasing evidence that it influences host plant choice and the probability of finding a mating partner in herbivorous insects. In this review, we will focus upon behavioural changes in holometabolous insect herbivores during host plant choice and localization of mating partners, modulated by experience to sensory cues. The experience can be acquired during both the larval and the adult stage and can influence later responses to plant volatiles and other sensory cues not only within the developmental stage but also after metamorphosis. Furthermore, we will address the neurophysiological mechanisms underlying the experience-dependent behavioural adaptations and discuss ecological and evolutionary aspects of insect behavioural plasticity based upon experience.
植物挥发物是许多植食性昆虫选择合适寄主植物和寻找交配对象时的重要线索。对来自植物和其他昆虫的感官线索做出适当的行为反应对于生存和适应性至关重要。由于自然环境在空间和时间上都具有很大的变异性，食草动物可能需要对可用线索表现出行为可塑性。通过利用早期经验，昆虫可以适应资源的局部变化。众所周知，经验会影响寄生蜂和社会性昆虫的感官引导行为，但越来越多的证据表明，它也会影响植食性昆虫对寄主植物的选择以及找到交配对象的概率。在这篇综述中，我们将重点关注全变态昆虫食草动物在寄主植物选择和交配对象定位过程中的行为变化，这些变化受对感官线索的经验调节。这种经验可以在幼虫期和成虫期获得，并且不仅可以在发育阶段内，还可以在变态后影响对植物挥发物和其他感官线索的后续反应。此外，我们将探讨经验依赖性行为适应背后的神经生理机制，并讨论基于经验的昆虫行为可塑性的生态和进化方面。
