A nuclear ribosomal DNA pseudogene in triatomines opens a new research field of fundamental and applied implications in Chagas disease

Memorias do Instituto Oswaldo Cruz, 2015
A pseudogene, designated as "ps(5.8S+ITS-2)", paralogous to the 5.8S gene and internal transcribed spacer (ITS)-2 of the nuclear ribosomal DNA (rDNA), has been recently found in many triatomine species distributed throughout North America, Central ...

The P2X7 Receptor and Its Relation to Neglected Tropical Diseases: Focusing on Chagas Disease

Journal of Tropical Medicine, Volume 2026, Issue 1, 2026.
Chagas disease, caused by Trypanosoma cruzi, is a neglected tropical disease (NTD) that can lead to severe cardiac complications, including chronic Chagas cardiomyopathy. While NTDs are caused by a variety of pathogens—such as protozoa, bacteria, viruses, and helminths, Chagas disease remains underexplored, particularly regarding host immune responses.

Genetic basis of triatomine behavior: lessons from available insect genomes

Memorias do Instituto Oswaldo Cruz, 2013
Triatomines have been important model organisms for behavioural research. Diverse reports about triatomine host search, pheromone communication in the sexual, shelter and alarm contexts, daily cycles of activity, refuge choice and behavioural plasticity ...

A new piece in the repeatome puzzle of Triatominae bugs: The analysis of Triatoma rubrofasciata reveals the role of satellite DNAs in the karyotypic evolution of distinct lineages

Insect Molecular Biology, Volume 34, Issue 6, Page 917-928, December 2025.
Satellite DNAs comprise the major component of the Triatoma rubrofasciata repeatome, highlighting their central role in genome composition and architecture. Satellite DNA families show recent amplification in heterochromatin and older, more divergent satellite DNAs located in euchromatin, indicating distinct evolutionary histories.

Behavior of triatomines (Hemiptera, Reduviidae) vectors of Chagas' disease. II. Influence of feeding, lighting and time of day on the number of mating, mating speed and duration of copulation of Panstrongylus megistus (Burm, 1835) under laboratory conditions

Memorias do Instituto Oswaldo Cruz, 1986
To determine in influence of feeding, lighting and time of day on the copulating behavior of Panstrongylus megistus, 480 insect pairs were divided into four groups of 120 each and tested in the following respective situations: without food deprivation (F.

Trypanosoma cruzi circulating among dogs and triatomines in the endemic countryside of the State of Rio Grande do Norte, Brazil.

Acta Tropica, 2019
Vector transmission of Trypanosoma cruzi occurs in several areas of Brazil, including the northeastern region, and domestic animals can serve as reservoirs of the parasite. The aim of this study was to monitor dogs as domestic reservoirs for infection by

Potential geographic displacement of Chagas disease vectors under climate change

Medical and Veterinary Entomology, Volume 39, Issue 4, Page 709-717, December 2025.
As a result of modelling the potential distribution of 55 triatomine species in the Neotropical region, with climate change projected for up to 2050, we found no significant changes. With climate change projected for up to 2080 in the Neotropical region, we see a significant potential for the migration of 55 species of triatomines towards the Amazon ...
