The goal of this work is to investigate how Armadillo officinalis modulates its behavior in terms of turn alternation when exposed to micro-vibrations propagating through a A T-maze with multiple exits was used to evaluate the turn alternation pattern in i) adult individuals of A. officinalis exposed or ii) not exposed to micro-vibrations, iii) juveniles of A. officinalis exposed, and vi) adult individuals of Armadillidium vulgare exposed. The generalized regression models used highlighted a significant association between the turn alternation pattern and the micro-vibration (not exposed/exposed), animal’s state (adults/juveniles), and species (A. vulgare/ A. officinalis). In particular, an average higher number of turn alternations was observed for the adults of A. officinalis exposed to the microvibrations compared to i) the not exposed adults, ii) the exposed juveniles, and iii) the exposed adults of A. vulgare. No significant association was instead highlighted between adults of A. officinalis not exposed and adults of A. vulgare exposed to the micro-vibration. Our results showed that A. officinalis seems to be very sensible to external vibrations, differently from A. vulgare. In addition, the sensitiveness to the vibrations seems increasing passing from the juvenile state to the adult condition. This sensitiveness might be linked to the peculiarity of this species to emit vibrations by means of a stridulatory organ.
