减少农业损失是可持续地提高农业产出效率以满足我们当前和未来对粮食、纤维、饲料和燃料的需求的有效途径。我们对植物应对生物和非生物胁迫的方式的理解不断提高，导致了创新传感技术的发展，用于检测作物胁迫/胁迫源并部署有效措施。本文旨在介绍目前应用于农业领域的方法对作物生物胁迫检测的现状。介绍了植物病原体（或植物病原体）以及食草昆虫/害虫的关键传感方法，其中描述了工作原理，并讨论了最近的关键工作。综述了植物病原体胁迫鉴定的检测方法，包括核酸检测法、免疫学检测法、图像检测法、光谱检测法、植物激素生物传感法、植物挥发物检测法和主动遥感技术。而与害虫相关的传感技术包括基于机器视觉的方法、害虫声发射传感器和基于挥发性有机化合物的压力监测方法。此外，不同的传感技术之间的比较，以及最近报道的作品，其中的优势和局限性被确定。最后，展望了作物生物胁迫监测的未来发展方向。
Reducing agricultural losses is an effective way to sustainably increase agricultural output efficiency to meet our present and future needs for food, fiber, fodder, and fuel. Our ever-improving understanding of the ways in which plants respond to stress, biotic and abiotic, has led to the development of innovative sensing technologies for detecting crop stresses/stressors and deploying efficient measures. This article aims to present the current state of the methodologies applied in the field of agriculture towards the detection of biotic stress in crops. Key sensing methodologies for plant pathogen (or phytopathogen), as well as herbivorous insects/pests are presented, where the working principles are described, and key recent works discussed. The detection methods overviewed for phytopathogen-related stress identification include nucleic acid-based methods, immunological methods, imaging-based techniques, spectroscopic methods, phytohormone biosensing methods, monitoring methods for plant volatiles, and active remote sensing technologies. Whereas the pest-related sensing techniques include machine-vision-based methods, pest acoustic-emission sensors, and volatile organic compound-based stress monitoring methods. Additionally, Comparisons have been made between different sensing techniques as well as recently reported works, where the strengths and limitations are identified. Finally, the prospective future directions for monitoring biotic stress in crops are discussed.
