Air sampling-based device for broad-spectrum collection and monitoring of edna from locust habitats

Abstract

The present invention discloses an air sampling-based device for broad-spectrum collection and monitoring of environmental DNA (eDNA) from locust habitats, relating to the field of agricultural pest monitoring. The device comprises a monitoring mechanism, with a power generation unit mounted at the top and a cleaning mechanism at the front. The cleaning mechanism includes a controller connected to an electric telescopic rod that drives a scraper to periodically clean the filter screen of the air sampling port. This automated cleaning reduces impurity blockage, ensures consistent airflow, and maintains sampling efficiency and eDNA purity. The system allows for long-term, unmanned operation, reducing labor costs and intervention while ensuring reliable and continuous monitoring. The combination of air sampling and automated filter cleaning makes the device suitable for remote field deployment in harsh locust-infested environments. It supports early warning systems, ecological research, and integrated pest management through high-quality eDNA data acquisition.
