Tracking the invasive hornet Vespa velutina in complex environments by means of a harmonic radar

Abstract An innovative scanning harmonic radar has been recently developed for tracking insects in complex landscapes. This movable technology has been tested on an invasive hornet species (Vespa velutina) for detecting the position of their nests in the environment, in the framework of an early det...
