This podcast episode examines research conducted at the Universidade Federal da Grande Dourados in Brazil, focusing on the development of a real-time pest detection system for soybean crops using the You Only Look Once (YOLO) architecture. The research aimed to address the challenges of accurately detecting and classifying 12 classes of soybean pests, including 10 distinct species with two further categorized into their adult and nymph stages.

The researchers created a new dataset, called INSECT12C-Dataset, composed of images of these pests captured in real-world field conditions, which presents variations in lighting, object size, occlusion, and background. The dataset, containing 2,758 annotated insects, was used to train and test the YOLO architecture for real-time pest detection.

The podcast will explore:

• The importance of soybean crops to the Brazilian economy and the significant impact of pests on soybean production.
• The challenges of pest detection, both in research and practical applications, due to environmental variability, pest camouflage, mobility, diversity, and the limitations of detection technologies.
• The specific difficulties in detecting all 12 soybean pest classes, including the impact of environmental factors, insect occlusion, data imbalance, and variations in pest appearance.
• Why accurately distinguishing between adult and nymph stages of certain species, like Euschistus heros, posed a particular challenge for the YOLO architecture.
• The researchers' findings, including the effectiveness of YOLO in real-time pest detection and the potential for future improvements using higher-resolution cameras, dataset balancing techniques, and the development of pesticide application maps.

This podcast episode will be of interest to:

• Farmers and agricultural professionals seeking to understand the latest advancements in pest detection and control technologies for soybean crops.
• Researchers and students in the fields of computer vision, artificial intelligence, and precision agriculture.
• Anyone interested in the applications of technology for sustainable agriculture and food security.
