This line includes Behavioural Physiology studies of triatomines,centred, principally, on the analysis of the intraespecificcommunication. We investigate the exocrine glands of kissing bugs whose secretions fulfil functions as sexual or alarm pheromones. We are interested in studying the chemical compounds released by these glands to determine if someone or a mixture of the released volatiles constitutesa relevant signal for these insects. Likewise, we evaluate the cuticularlipids as contact cues mediating sexual recognition. Additionally, we incorporate sublines on sexual selection and strategies of utilization of refuges. We analyze the underlying mechanisms behind the mate choice, in a frame of sexual selection, in order to identify the factors that influence the mate choicedepending on the variations of the type and quality of competition(intra and inter-sexual). Also, we study the factors that determine the dynamics of selection and utilization of refuges and how this affects on the intra and inter-specific competition.
