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.

昆虫种内嗅觉交流发生在复杂的感官环境中。在这里，我们展示了嗅觉系统如何从感官背景中提取特定信息，并将其与补充信息相结合以改善气味源定位的最新结果。综述了嗅觉混合处理机制、多模态整合以及感觉处理可塑性的最新进展。对神经编码和嗅觉分子基础的理解的重大进展加强了我们对昆虫对不断变化的环境的巨大适应性的认识。然而，一些报告表明，人为环境扰动会干扰昆虫的嗅觉交流，并可能因此显着改变生态系统和农业生态系统的功能。
