Phylogenetic multi-locus codon models and molecular clocks reveal the monophyly of haematophagous reduviid bugs and their evolution at the formation of South America.

open access: yes, 2010
We previously constructed a single molecular clock to date insect evolution that remains a cornerstone within entomological dating. The insect clock predicts that triatomine bugs, the vectors of South American trypanosomiasis, originated with the ...

Trypanosoma cruzi infection enhances olfactory response in Triatoma pallidipennis Stål (Hemiptera: Triatominae) to compounds potentially useful for insect control

open access: yesMedical and Veterinary Entomology, Volume 39, Issue 1, Page 160-170, March 2025.
Triatoma pallidipennis is one of the main vectors of Trypanosoma cruzi, the causative agent of Chagas disease. Attractant activity of octenol, nonanal and a mixture of lactic acid, hexanoic acid and ammonium hydroxide on T. cruzi–infected and non‐infected T. pallidipennis nymphal stages.

Primeiro relato de ocorrência da espécie Eratyrus mucronatus, Stal, 1859, (Hemiptera, Reduviidae, Triatominae), no Estado de Rondônia [PDF]

open access: yes, 2011
INTRODUCTION: This paper reports, for the first time, the presence of the Eratyrus mucronatus species in the State of Rondonia, Brazil. METHODS: These specimens were caught by chance in the forest and later they were collected using luminous traps ...

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

open access: yesSystematic 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 ...

Triatominae as a model of morphological plasticity under ecological pressure

open access: yesMemorias do Instituto Oswaldo Cruz, 1999
The use of biochemical and genetic characters to explore species or population relationships has been applied to taxonomic questions since the 60s. In responding to the central question of the evolutionary history of Triatominae, i.e.

Cytogenetic studies on Mepraia gajardoi (Heteroptera: Reduviidae). Chromosome behaviour in a spontaneous translocation mutant

open access: yesEuropean Journal of Entomology, 2004
We analysed the chromosome complement and male meiosis in a natural population of Mepraia gajardoi (Hemiptera: Reduviidae: Triatominae). The normal karyotype of this species is 20 autosomes plus X1X2Y in males and X1X1X2X2 in females. We confirmed that M.

Comparative descriptions of eggs from three species of Rhodnius (Hemiptera: Reduviidae: Triatominae) [PDF]

open access: yes, 2009
The authors describe and compare the morphological and ultrastructural characteristics of eggs from the three most recent described species of the genus Rhodnius Stål, 1859, which have not previously been studied. These species are Rhodnius colombiensis (

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

open access: yesJournal 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 ...
