This course is part of Module II: Technology and Practice on Grain Postharvest Loss Reduction within the webinar series on postharvest loss reduction organized by the WFP Centre of Excellence for Rural Transformation (WFP China COE). The series was held from August 27th to September 26th, 2024, with support from the Academy of China’s National Food and Strategic Reserves Administration (NAFRA).

The overall objective of this webinar series is to share China’s extensive experience, technologies, and practices in reducing postharvest loss. Across two modules—Module I: Experience on Grain Postharvest Management and Module II: Technology and Practice on Grain Postharvest Loss Reduction—a total of 16 Chinese presenters introduced China’s approaches to postharvest management and demonstrated key technologies applied by aggregators at various stages of the postharvest process.

Within this framework, the present course focuses on the technology and equipment for intelligent monitoring and early warning of stored grain pests. It outlines the research background, key scientific issues, and the integrated pest control technology system for stored grain. The course highlights the development and application of trapping technology, emphasizing online, realtime, accurate, and intelligent monitoring. It discusses the components of the electron probe trap, management software, pest imagery datasets, identification algorithms, and the overall management system. The course also presents field application testing and the monitoring and early warning of the distribution of major stored grain pests.
