Abstract: Diseases and pests are important factors affecting fruit quality grading. During the process of growth, processing, storage and transportation, fruit are susceptible to pathogens and pests, reducing fruit quality and causing adverse effects on food safety. Recent progress in the application of X-ray imaging, computer vision, nuclear magnetic resonance, spectroscopy and emerging sensors for the non-destructive detection of fruit diseases and pests is summarized in this article. Furthermore, the advantages and disadvantages of each technology are also analyzed, and particular focus is placed on the application of hyperspectral imaging technique in this field. Finally, existing problems and future directions are proposed in order to provide useful information for further research.

Key words: fruit, diseases, pests, non-destructive detection technologies, hyperspectral imaging technology
