Abstract:Chemical senses play a critical role in the ecology and behavior of lizards and snakes. However, evidence of prey chemical discrimination in the Turpan wonder gecko, Teratoscincus roborowskii, a rare frugivorous gecko endemic to China, is not clear. In this experiment, we studied lingual responses by this gecko to single representatives of three major categories of food chemicals, sucrose as a carbohydrate, pure pork fat as a lipids mixture and soy protein powder as a protein. In addition, distilled water was used as a control. All stimuli were presented on cotton swabs in 60-sec tongue-flicks trials. The indices of tongue-flicks rate (TFR) and tongue-flicks attack scores (TFAS(R)) were used to investigate the chemical identification modes on different types of food. Our results showed that the Turpan wonder gecko did responded to all three stimuli and we listed the corresponding number of TFR and TFAS(R). The TFR value in reponse to the distilled water and the saturated sugar solution were significantly greater than that to the lipids , while the TFAS(R) in reponse to the lipids was significantly larger than that to the distilled water and to the saturated sugar solution. These findings indicate that Turpan wonder gecko is capable of using vomeronasal organ to detect and identify these several types of food compound stimuli.
