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.

Rhodnius prolixus nymphs and adult

* Rhodnius prolixus

Saliva of the blood-sucking bug Rhodnius prolixus contains at least seven homologous nitrophorins, designated NP1 to NP7 in order of their relative abundance in the glands.

The salivary nitrophorin from the hemipteran Cimex lectularius ( bedbug ) has no sequence similarity to Rhodnius prolixus nitrophorins but is homologous to the inositol-polyphosphate 5-phosphatase ().

The Rhodnius prolixus nitrophorin structures reveal lipocalin-like eight-stranded β-barrel, three α-helices and two disulfide bonds, with heme inserted into one end of the barrel.

* Rhodnius pallescens Barber, 1932 ( Tc ) ( principal vector in Panama ).

In this study, two adult Rhodnius had their blood systems linked, ensuring that the JH titre in both would be equal.

One was a third instar Rhodnius, the other was a fourth instar.

When the fourth instar Rhodnius had its corpora allata removed, both contained a third instar level of JH and hence one proceeded to instar four, and the other remained at this instar.

Triatoma species and other members of the subfamily Triatominae, such as Rhodnius species, Panstrongylus megistus and Paratriatoma hirsuta, are known as kissing bugs because they tend to bite sleeping humans in the soft tissue around the lips and eyes.
