Participation of chemical cues in conspecific detection and sexual discrimination in Boa constrictor occidentalis Serpentes, Boidae Participacion de senales quimicas en el reconocimiento y discriminacion de sexos en Boa constrictor occidentalis Serpentes, Boidae



Gayana 651: 5-10



The use of chemical signals to recognize and to discriminate conspecifics, has been demonstrated in some species of snakes. The behavior in chemio sensorial communication context of boid snakes is known in genus Epicrates. The ability of Boa constrictor occidentalis to detect chemical signals from conspecifics was tested in this paper in order to specify if skin and scent cloacal glands participate in sexual discrimination in this specie. Responses to skin and cloacal conspecifics odor stimuli was assessed by measuring the frequency of tongue flicks. Results show that both males and females detect conspecifics odor and that these secretions participate in sexual discrimination, suggesting an important role of quimior reception in reproductive context in this species.
