Pheromones and other semiochemicals play an important role in the natural world by influencing the behavior of plants, mammals, and insects. In the latter case, species-dependent pheromone communication has numerous applications, including the detection, trapping, monitoring and guiding of insects, as well as pest management in agriculture. On-site sensors are desirable when volatile organic compounds (VOCs) are used as semiochemicals. Insects have evolved highly selective sensors for such compounds, so biosensors comprising complete insects, isolated organs or individual proteins can be highly effective. However, isolated insect organs have a limited lifetime as biosensor, so biomimetic approaches are needed for prolonged monitoring, novel applications, or measurements in challenging environments. We discuss the development of on-site biosensors and biomimetic approaches for airborne-pheromone sensing, together with biomimetic VOC sensor systems. Furthermore, the infochemical effect describing the anthropogenic contamination of the ecosystem through semiochemicals, will be considered in the context of novel on-site pheromone sensing-systems.
信息素和其他化学生态因子在自然界中起着重要作用，影响着植物、哺乳动物和昆虫的行为。在后一种情况下，依赖于物种的信息素通讯有许多应用，包括昆虫的检测、诱捕、监测和引导，以及农业中的害虫管理。当挥发性有机化合物 (VOC) 用作化学生态因子时，现场传感器是理想的选择。昆虫已经进化出对这些化合物具有高度选择性的传感器，因此包含完整昆虫、分离器官或单个蛋白质的生物传感器可以非常有效。然而，分离的昆虫器官作为生物传感器的寿命有限，因此需要仿生方法来进行长时间监测、新的应用或在具有挑战性的环境中的测量。我们讨论了现场生物传感器和仿生方法的发展，用于空气传播信息素的传感，以及仿生 VOC 传感器系统。此外，还将根据新型现场信息素传感系统，考虑描述通过化学生态因子对生态系统人为污染的信息素效应。
