Stored grain insect pest is one of the main factors which can endanger the food security. The pests detection technologies have very important significance for grain integrated management. In this paper, different types of detection technologies were generalized and summarized, such as traditional detection methods, new physical detection methods and biological detection methods. Traditional detection methods, such as visual inspection, sample sieving, grain probes and insect traps, are more mature and have been standardized. Physical detection methods such as near-infrared spectroscopy (NIR) and hyperspectral spectroscopy, soft X-ray, electrical conductance, microwave radar, image recognition, acoustic measurement, and electronic nose are more innovative, mainly in rapid and non-destructive type of detection method. Biological detection methods such as biological trap are mostly assisted methods, and usually combine with other methods to achieve optimum detection results. The advantages and disadvantages of various methods were deeply compared and the latest domestic and overseas pests detection technologies were finally discussed, in order to provide a reference for the future development of suitable detection methods and instruments.
