Primer registro de Triatoma infestans (Klug) (Hemiptera: Reduviidae) asociado a nidos de loros barranqueros (Cyanoliseus patagonus) (Aves: Psittacidae)

Triatoma infestans is the most important vector of Chagas disease in Argentina. We report for the first time the presence of T. infestans (Klug) (Hemiptera: Reduviidae) associated with burrowing parrot nests Cyanoliseus patagonus (Psitta- siformes: Psittacidae) built on abandoned adobe houses. The possible implications of this finding are discussed, for entomological surveillance of the vector.
