Abstract

Several studies strongly imply that the desert locust (Schistocerca gregaria) is able to use polarized light patterns in the sky for orientation tasks. A specialized region in its compound eye (DRA) contains photoreceptor cells which are morphologically adapted for the detection of polarized light. This work focuses on the physiological and morphological examination of photoreceptor cells inside and outside the DRA. By applying electrophysiological methods it was tested for spectral, absolute, polarization and angular sensitivity of receptor cells by using electrophysiological methods. Tracer injections revealed projection patterns of the respective cells. In addition data of the solitarious and gregarious phase of the desert locusts were compared.
