The GPS-guided deployment technology integrates UAV, GPS, and a cloud-based platform to automate the release of parasitoid wasp balls. It precisely plans flight routes and deployment locations based on field boundaries, achieving an operational capacity of 5–10 ha per hour with a 90% deployment success rate. Compared with conventional manual deployment, the system improves efficiency by sixfold, providing a precise, labor-saving, and sustainable solution for biological pest control.
