Population Biology of Rhodnius domesticus Neiva & Pinto, 1923 (Hemiptera: Reduviidae) under Laboratory Conditions

open access: yesMemorias do Instituto Oswaldo Cruz, 1998
The entire life cycle of Rhodnius domesticus, fed weekly on mice, was studied under controlled conditions. Aspects related to hatching, life time, mortality, feeding behaviour and fecundity for each stage of the insect life-cycle were evaluated.

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

open access: yes, 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.

Effects of the alarm pheromone on Triatoma pallidipennis behaviour

open access: yesPhysiological Entomology, Volume 50, Issue 4, Page 374-387, December 2025.
T. pallidipennis performs behavioural acts in response to volatiles emitted by mechanically disturbed conspecifics. T. pallidipennis shows a repellent response when exposed to volatiles emitted by mechanically disturbed conspecifics. Isobutyric and propanoic acids can be used as repellents of T. pallidipennis. Abstract Adults of some Triatomine species,

Ecological host fitting of Trypanosoma cruzi TcI in Bolivia: mosaic population structure, hybridization and a role for humans in Andean parasite dispersal. [PDF]

open access: yes, 2015
An improved understanding of how a parasite species exploits its genetic repertoire to colonize novel hosts and environmental niches is crucial to establish the epidemiological risk associated with emergent pathogenic genotypes.

Effects of TcFLA‐1BP and TcGP72 Deletion on the Infectivity and Survival of Trypanosoma cruzi in Cell Cultures

open access: yesCell Biology International, Volume 49, Issue 11, Page 1395-1410, November 2025.
ABSTRACT Chagas disease, caused by the protozoan Trypanosoma cruzi, is a neglected tropical disease with limited treatment options and no available vaccine. Understanding the role of proteins in the parasite's biological cycle is critical for advancing vaccine development and optimizing therapies.

Oogenesis and egg development in triatomines: a biochemical approach [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2005
In triatomines, as well as in other insects, accumulation of yolk is a process in which an extra-ovarian tissue, the fat body, produces yolk proteins that are packed in the egg. The main protein, synthesized by the fat body, which is accumulated inside the oocyte, is vitellogenin. This process is also known as vitellogenesis.

In Vitro Impact of Triatomine Salivary Glands Extracts Introduced to Endothelial Cells [PDF]

open access: yes, 2018
Chagas Disease (AKA Trypanosomiasis) is caused by biting/feeding behavior from the arthropod vector Triatoma (subfamily of Reduviidae family), that house the endoparasite Trypanosoma cruzi, which can then be passed to human and mammalian hosts (Schmidt ...

The Ly49E receptor inhibits the immune control of acute Trypanosoma cruzi infection [PDF]

open access: yes, 2016
The protozoan parasite Trypanosoma cruzi circulates in the blood upon infection and invades various cells. Parasites intensively multiply during the acute phase of infection and persist lifelong at low levels in tissues and blood during the chronic phase.

Natural Products from Mexican Medicinal Plants as Promising Trypanocidal Drugs

open access: yesChemistrySelect, Volume 10, Issue 37, October 6, 2025.
Chagas disease (American Trypanosomiasis) is caused by the protozoan Trypanosoma cruzi. Worldwide it is one of the seventeen neglected tropical diseases. There is a need of new drugs. This review assesses the literature (2012‐2024) of secondary metabolites isolated from Mexican plants active against this parasite.
