LOBBIA, Patricia A.; ALVAREZ, Rodrigo; PICOLLO, María I.  and  MOUGABURE-CUETO, Gastón. First record of domestic colonies of the dark chromatic variant of Triatoma infestans (Hemiptera: Reduviidae). Rev. Soc. Entomol. Argent. [online]. 2019, vol.78, n.3, pp.1-10. ISSN 0373-5680.

Triatoma infestans (Klug) is the main vector of Chagas disease in southern South America. Although this species shows a similar morphology and chromatic pattern throughout its geographical distribution, some melanic variations have been described. Most of these variants were recognized as part of wild populations constituting evidence of a wild distribution for T. infestansgreater than the expected. This paper reports the presence of eight adults and ffteen immature individuals of melanic T. infestansin domiciliary units of Argentine Gran Chaco. This is the frst report of domestic colonies of the dark chromatic morph of T. infestans.
