For stored grains and their powders, pest infestation has always been a knotty problem and thus comprises a serious threat to global food security. Obviously, timely, rapid and accurate pest detection methods are of extreme importance to protect grains from pest mouth. In facing the defects of traditional methods, such as visual inspection, grain flotation and pest trap, diverse innovative approaches progressed fast alternatively, either targeting pest itself or diagnosing pest-induced changes. The former includes machine vision, metabolite analysis, pest-specific protein techniques, molecular techniques, bioacoustics analysis, conductive roller mill, low-field nuclear magnetic resonance spectroscopy and imaging, while the latter consists of thermal imaging, near-infrared spectroscopy and hyperspectral imaging, impact acoustics analysis, soft X-ray imaging and tomography. The principle, operation procedure, pros and cons and application scenarios were discussed for each method. The results herein hope to promote the technical revolution of pest inspection in stored cereal grains and their powders.
对于储存的谷物及其粉末,虫害一直是一个棘手的问题,因此对全球粮食安全构成了严重威胁。显然,及时、快速、准确的虫害检测方法对于保护谷物免受虫害至关重要。面对传统方法(如目视检查、谷物浮选和害虫诱捕)的缺陷,各种创新方法迅速发展,要么针对害虫本身,要么针对害虫引起的变化进行诊断。前者包括机器视觉、代谢物分析、害虫特异性蛋白技术、分子技术、生物声学分析、导电辊磨、低场核磁共振波谱和成像,后者包括热成像、近红外光谱和高光谱成像、冲击声学分析、软 X 射线成像和层析成像。本文讨论了每种方法的原理、操作程序、优缺点及应用场景。希望本文的研究结果能够推动储粮及其粉末中虫害检测技术的革命。
