Semiochemicals are chemical compounds that are released by many species as a means of intra- and interspecific communication. Insects have extremely advanced olfactory systems; indeed, they rely on smell when performing many of their main behaviors, such as oviposition, breeding, prey location, and defense. This characteristic of insects implies that semiochemicals could be used for various applications, including in agriculture, where they could be employed along with other tools to control pest insects. The aim of this review is to present the main techniques used and the state of the art in the detection of semiochemicals, focusing on pheromones. In addition to the traditional methods of identifying semiochemicals, such as gas chromatography coupled to a high-resolution detection mode (e.g., flame ionization (FID), electron capture (ECD), photoionization (PID), or mass spectrometry (MS)), other tools are addressed in this review, including sensors and biosensors. While these new technologies may be used under laboratory conditions to improve or complement technologies that are already being used, they are mainly intended for use as new agricultural tools for detecting and controlling pest insects in the field.
信息素是许多物种释放的化学化合物，是它们进行种内和种间交流的一种方式。昆虫具有极其先进的嗅觉系统；事实上，它们在执行许多主要行为（如产卵、繁殖、寻找猎物和防御）时都依赖于嗅觉。昆虫的这一特性意味着信息素可用于各种应用，包括农业领域，可与其他工具一起用于控制害虫。本文旨在介绍检测信息素（特别是信息素）的主要技术和最新技术，除了识别信息素的传统方法，如气相色谱法与高分辨率检测模式（例如火焰离子化（FID）、电子捕获（ECD）、光离子化（PID）或质谱法（MS））相结合外，本文还介绍了其他工具，包括传感器和生物传感器。虽然这些新技术可在实验室条件下用于改进或补充已经使用的技术，但它们主要旨在作为用于田间检测和控制害虫的新型农业工具。
