Abstract:Chemical senses play a critical role in the ecology and behavior of lizards. 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 study, the lingual responses of this gecko to single representatives of 3 major categories of food chemicals were investigated. Saturated sugar solution was used as a carbohydrate, pure pork fat as a lipids mixture and soy protein powder solution as a protein. In addition, distilled water was used as control. All stimuli were presented on cotton swabs in 60-sec tongue-flicks trials. Tongue-flicks rate (TFR) and tongue-flicks attack scores[TFAS(R)] were used to determine the chemical identification modes on different stimuli. Our results showed that the T. roborowskii would respond to all 3 stimuli. The TFR value in reponse to the distilled water and the saturated sugar solution were extremely significantly or significantly greater than that to lipids, while the TFAS(R) in response to lipids was extremely significantly higher than that to distilled water and saturated sugar solution. These findings indicated that T. roborowskii is capable of using vomeronasal organ to detect and identify several types of food chemicals.
