Triatominae
The members of Triatominae , a subfamily of Reduviidae, are also known as conenose bugs, kissing bugs, assassin bugs, or triatomines. Most of the 130 or more species of this subfamily are haematophagous, i.e. feed on vertebrate blood; a very few species feed on other invertebrates (Sandoval ''et al.'' 2000, 2004). They are mainly found and widespread in the Americas, with a few species present in Asia, Africa, and Australia. These bugs usually share shelter with nesting vertebrates, from which they suck blood. In areas where Chagas disease occurs (from the southern United States to northern Argentina), all triatomine species are potential vectors of the Chagas disease parasite ''Trypanosoma cruzi'', but only those species (such as ''Triatoma infestans'' and ''Rhodnius prolixus'') that are well adapted to living with humans are considered important vectors.
==History==
At the beginning of the 19th century Charles Darwin made one of the first reports of the existence of triatomines in America in his ''Journal and Remarks'', published in 1839 and commonly known as ''The Voyage of the Beagle''. The following is an extract which he based on his journal entry dated 26 March 1835:
There has been considerable medical speculation as to whether or not Darwin's contact with triatomines in Argentina was related to his later bouts of long term illness, though it is unlikely to have been caused on this specific occasion as he made no mention of the fever that usually follows the first infection.〔
