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 ...

Peridomestic structure, farming activity and triatomine infestation [PDF]

Parasite, 2006
The role of peridomestic structure and farming activity on triatomine infestation was studied on two vector species of Chagas disease (Triatoma pseudomaculata and T. brasiliensis) in Bahia State, northeastern Brazil. A randomly selected population issued from 136 farms was divided into four categories according to the householder activity.

Influye la alimentación sobre el dimorfismo sexual en Triatoma infestans (Hemiptera, Reduviidae) de hábitats naturales? [PDF]

, 2018
Triatoma infestans es el principal vector del parásito que causa la enfermedadde Chagas en Sudamérica. Se sabe que T. infestans tiene diferentes patrones reproductivosy de desarrollo dependiendo de si se alimentan de aves o mamíferos.

Automated identification of spotted‐fever tick vectors using convolutional neural networks

Medical and Veterinary Entomology, Volume 39, Issue 4, Page 829-841, December 2025.
We evaluate the performance of convolutional neural networks (CNN) AlexNet, ResNet‐50 and MobileNetV2 for the automated identification of tick species capable of transmitting spotted fever. CNNs achieved accuracy rates of ~90% in identifying ticks and showed sensitivities of 59%–100% according to species, sex, position or image resolution.

Sugar feeding in triatomines: a new perspective for controlling the transmission of Chagas disease

Frontiers in Physiology
Introduction: Triatomines are vectors of Trypanosoma cruzi, the etiological agent of Chagas disease. Currently, there is no vaccine against this disease. Thus, control of the insect vector population is the main strategy available to reduce the number of

Effects of the alarm pheromone on Triatoma pallidipennis behaviour

Physiological 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,

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

Cell 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.
