History of insecticide resistance of Triatominae vectors

Revista da Sociedade Brasileira de Medicina Tropical, 2015
In the last 15 years, different types of Triatominae resistance to different insecticides have been reported; thus, resistance may be more widespread than known, requiring better characterization and delimitation, which was the aim of this review.

Biosystematics and evolution of the Triatominae [PDF]

Cadernos de Saúde Pública, 2000
In this paper we summarize the systematics of the 130 currently recognized species of Triatominae and the key features of their evolutionary background. There is increasing evidence that the subfamily has polyphyletic origins, with the various tribes and species groups probably arising from different reduviid lineages in relatively recent times.

Empowering communities through One Health and ArtScience: An innovative approach to combat Chagas disease in endemic areas of Minas Gerais, Brazil

Public Health Challenges, Volume 4, Issue 1, March 2025.
This study combines One Health and ArtScience to address Chagas disease in Latin America through Chagas Express XXI in Minas Gerais, Brazil. Six workshops revealed significant gaps in local understanding of transmission and control, emphasizing the need for education tailored to endemic socio‐environmental contexts.

Deciphering morphology in Triatominae: The evolutionary signals

Acta Tropica, 2009
Many species of Triatominae show evidence for morphological plasticity. Frequent taxonomic questions arose from this variability leading to disputes about describing new subspecies, species or even genera. We suggest this phenotypic flexibility is primarily an intraspecific feature, but with potential for evolutionary changes.

A revised classification of the assassin bugs (Hemiptera: Heteroptera: Reduviidae) based on combined analysis of phylogenomic and morphological data

Systematic Entomology, Volume 50, Issue 1, Page 102-138, January 2025.
This study produces the first combined morphological and molecular phylogenetic analysis for Reduviidae and reveals synapomorphies and diagnostic traits for clades at the ranks of subfamilies and tribes. Based on our resulting robust phylogenetic reconstructions and subsequent optimization of morphological character information, we propose a ...

Everybody loves sugar:first report of plant feeding in triatomines [PDF]

, 2016
Background Triatomines, which are the vectors of Trypanosoma cruzi, have been considered to be exclusive blood feeders for more than 100 years, since the discovery of Chagas disease.

Apoptosis: A Key Process That Trypanosoma cruzi Modulates as a Strategy to Perpetuate Infection

Journal of Parasitology Research, Volume 2025, Issue 1, 2025.
Apoptosis is a crucial host defense mechanism because it can trigger the immune response and get rid of infected cells. These important goals, among others, are achieved through a fine‐tuned process that culminates in a quiet form of cell death. Apoptosis represents a hindrance for intracellular microorganisms that live inside cells. Nevertheless, they

Morphometric characterization of Rhodnius pictipes Stål, 1872 (Hemiptera: Reduviidae) eggs in Eastern Brazilian Amazon populations

Revista Chilena de Entomología
Triatomines are potential vectors of Trypanosoma cruzi, the causative agent of Chagas disease, and are prevalent in the Amazon region of Brazil. This study focuses on the detailed morphometry of Rhodnius pictipes eggs to enhance understanding of their ...

Monocyte‐derived extracellular vesicles, stimulated by Trypanosoma cruzi, enhance cellular invasion in vitro via activated TGF‐β1

Journal of Extracellular Vesicles, Volume 13, Issue 11, November 2024.
Abstract During cell invasion, large Extracellular Vesicle (lEV) release from host cells was dose‐dependently triggered by Trypanosoma cruzi metacyclic trypomastigotes (Mtr). This lEV release was inhibited when IP3‐mediated Ca2+ exit from the ER and further Ca2+ entry from plasma membrane channels was blocked, but whilst any store‐independent Ca2 ...
