Maize (also known as corn) has played an important role in human agriculture ever since its domestication by indigenous peoples of Mexico some 10,000 years ago. The crop is now planted across the world, including in China. However, several invasive pests, including the fall armyworm Spodoptera frugiperda, have threatened this crop and lowered yield. Eupeodes corollae, an endemic syrphid hoverfly, has been proposed as a biological control agent. Here, students will explore the antagonistic relationship between S. frugiperda and E. corollae, with both species feeding on larvae of the other species, and learn about type III functional …

California, known for its diverse agriculture, is also a major producer of rice, especially in its northern regions in Sacramento River Valley. Traditional methods, predominantly reliant on optical-based satellite imagery, encounter limitations due to atmospheric interference and sensor resolution. The ability of Synthetic Aperture Radar (SAR) to penetrate atmospheric distortions and exhibit high sensitivity to vegetation structure presents a distinct advantage over optical-based methods. Utilizing Optical and SAR data fusion, this study advances the enhanced pixel-based phenological feature composite (Eppf) method using SVM classification algorithm, which can track phenological changes and patterns, providing valuable insights for agricultural planning and management. …
