Insect intraspecific olfactory communication occurs in a complex sensory environment. Here we present recent results on how the olfactory system extracts specific information from a sensory background, and integrates it with complementary information to improve odor source localization. Recent advances on mechanisms of olfactory mixture processing, multi-modal integration, as well as plasticity of sensory processing are reviewed. Significant progress in the understanding of neural coding and molecular bases of olfaction reinforce our perception of the tremendous adaptability of insects to a changing environment. However several reports demonstrate that anthropogenic environmental perturbations interfere with insect olfactory communication and might as a consequence significantly alter the functioning of ecosystems and agroecosystems.
昆虫种内嗅觉通讯发生在复杂的感觉环境中。在这里，我们介绍了最近的研究结果，说明了嗅觉系统如何从感觉背景中提取特定信息，并将其与互补信息整合，以改善气味源定位。综述了嗅觉混合物处理、多模态整合以及感觉处理可塑性的机制的最新进展。对神经编码和嗅觉分子基础的理解取得了重大进展，这增强了我们对昆虫对不断变化的环境的巨大适应能力的认识。然而，有几项报告表明，人为的环境干扰会干扰昆虫的嗅觉通讯，并可能因此严重改变生态系统和农业生态系统的功能。
