Abstract and Summary
Workers of Polistes gallicus were displaced in transparent plexiglass test tubes, which allowed them sight of the sky, sun and landscape and then released, in a series of trials at various distances from the nests, in the open and in confined conditions (using an arena) to assess their ability of initial orientation and homing.
Results show that the workers are able to show the correct homeward direction independently of release distance, vision of the surrounding landscape and motivation. Homing times and homing performance, on the other hand, depend on release distance and motivation. The possibility that information gained during displacement plays a part in initial orientation is also discussed.
