Avoidance and locomotor behaviours of Armadillidium granulatum Brandt, 1833 collected from sebkha El Ouafi were studied. Avoidance test was conducted in individuals exposed to zinc contaminated soils. Globally, the animals did not show an avoidance behaviour after 48 h of exposure. The determined concentration effect of this metal was equal to 1043 mg/L. The locomotor activity rhythm was studied in the control animals as well as those exposed to Zn contaminated soils. The results revealed the existence of nocturnal behaviour whatever the experimental conditions. Furthermore, the Periodogram analysis showed the existence of ultradian and circadian periods. This latter was longer for contaminated specimens than the control ones under entraining conditions as well as under constant darkness. In addition, exposed animals showed the most important activity time whatever the regimen imposed and were characterized by a phase advance contrary to the control animals which showed a phase delay.
