In the areas where triatomine bugs have not adapted to human habitations, colonies of these insects have been found in houses occupied by sylvatic or sinanthropic mammals. Bloodmeal identifications from triatomine collected in human habitations and their surroundings usually correlate with those from specimens collected in natural biotopes, when two groups of data are considered, those from birds and mammals. This information related to the food preferences of the more fully studied triatomine and the occurrence of the pre-adaptation to […]

Spontaneous colonies of Triatoma infestans, T. sordida and Rhodnius neglectus developed in experimental fowlhouses were observed for the conditions under which they developed, their variations, permanence, annual cycles and survival. Of nine of these colonies three were mixed, one of them with T. infestans and T. sordida and two with T. sordida and R. neglectus. For all the triatomine species the colonies’ development showed a cyclic rhythm with an increase of the production of adults in the first semester of […]
