The spatial pattern of defaecation in Triatoma infestans and the role of faeces as a chemical mark of the refuge

Triatominae bugs aggregate around their faeces which carry an assembly signal. Here the biological role of the signal is studied for Triatoma infestans. We describe a stereotypic behaviour of T. infestans where the insects exit from shelters in order to defaecate. A higher concentration of faecal de...
