Sci Rep 15, 29858 (2025). https://doi.org/10.1038/s41598-025-15613-5Date: Received - 11 April 2025 | Accepted - 08 August 2025 | Published - 14 August 2025Executive SummaryThis document outlines a novel, automated insect monitoring system that uses electrical field sensors and artificial intelligence to provide a non-invasive, continuous alternative to traditional methods. The system addresses the critical need for improved insect monitoring in the face of global declines, aiming to overcome the labor-intensive, lethal, and temporally limited nature of conventional techniques like Malaise traps.The core technology detects atmospheric electrical field modulations caused by flying insects. A differential sensor design suppresses environmental noise, while a cloud-based AI pipeline processes the signals. This pipeline employs a Convolutional Neural Network (CNN) for insect detection, a probabilistic algorithm for Wing-Beat Frequency (WBF) analysis, and a lookup-based algorithm for biomass estimation.A field validation study conducted in a Danish nature reserve compared the system against standard Townes Malaise traps. The results demonstrated a moderate to strong positive correlation between sensor and trap data for insect counts (Spearman’s ρ up to 0.725). However, the correlation for biomass was weaker and not consistently significant. A major discrepancy in magnitude was observed, with sensors recording approximately three times more insect counts and 26 times more biomass than the traps. This is attributed to fundamental methodological differences (passive sensing vs. single capture) and significant uncertainty within the system's current biomass estimation algorithm.Notably, the sensor system exhibited higher measurement consistency...","thumbnail_url":"https://img.transistorcdn.com/qJYlR2Phxe3IMx6KHnsmKp1D71DIqj8LuYMSrDKo9Jc/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS82MDgx/MDIyNmJkNWU5YmIz/NzJhZDVmZjYyOGZi/NTgxMi53ZWJw.webp","thumbnail_width":300,"thumbnail_height":300}
