储粮害虫声信号的检测和应用

DETECTION AND APPLICATION OF ACOUSTICAL SIGNALS OF PESTS IN STORED GRAIN

与传统的储粮害虫检测方法相比 ,害虫的声测报技术作为一种快速、实用的新方法 ,正日益受到重视 .近年来 ,这一领域在微电子设备及计算机技术的推动下 ,取得了很大进展 .已由最初在小容器谷物样品中监测钻蛀为害粮粒害虫声音的技术 ,发展到目前实仓多点监测储粮害虫声音的微机监控系统 ,实现了对储粮害虫侵害程度的量化 ,通过声信号识别害虫种类方面的工作也在进一步的研究中 .文章综述了储粮害虫声测报领域的发展历程 ,最新进展及存在问题 .

Compared with traditional inspection methods,the technique of detecting acoustic signals of pests in stored grain is a quick and practical method which is attracting increasing attention.In recent years much progress in this field has been made due to improvements with microelectronic and computer techniques.The technology has advanced from the detection of acoustic signals of pests that feed inside grain kernels in small vessels to automated computer based acoustical monitoring systems that can quantify the infestation by pests. Identification of the species of grain beetle is also under investigation.The history,latest developments and unsolved problems of this technology are reviewed.
