Aggregation Behaviour and Interspecific Responses in Three Species of Triatominae
The response to intra- and interspecific assembling signals was tested in three species of Chagas' disease vectors. As previously describedfor Triatoma infestans, larvae of both species, T. sordida and T. guasayana, aggregated on papers impregnated with their own excrement. Moreover, bugs belon...

| Sumario: | The response to intra- and interspecific assembling signals was tested in three species of Chagas' disease vectors. As previously describedfor Triatoma infestans, larvae of both species, T. sordida and T. guasayana, aggregated on papers impregnated with their own excrement. Moreover, bugs belonging to each of the three species also aggregated on papers contaminated with faeces from the other two, with the only exception of the larvae of T. guasayana, which did not assemble on faeces of T. sordida. In all cases, the response to interspecific excrement was as strong as that to the intraspecific one. The non-specificity of the signal is discussed in the context of the ecological association of the three species and their role as vectors of Chagas ' disease. |
