Trends in evolution of the Rhodniini tribe (Hemiptera, Triatominae): experimental crosses between Psammolestes tertius Lent & Jurberg, 1965 and P. coreodes Bergroth, 1911 and analysis of the reproductive isolating mechanisms

Parasites & Vectors, 2021
Background The tribe Rhodniini is a monophyletic group composed of 24 species grouped into two genera: Rhodnius and Psammolestes . The genus Psammolestes includes only three species, namely P. coreodes , P. tertius and P. arthuri .

Topographic Barriers and Lowland Corridors Structure Gene Flow in the Chagas Vector Rhodnius pallescens Across the Isthmian Forests

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim Biogeographic processes can profoundly shape the connectivity and evolutionary potential of arthropod disease vectors. We investigated how Panama's ecological and topographic transitions structure populations of the kissing bug Rhodnius pallescens, the primary vector of the Chagas disease agent Trypanosoma cruzi in the region.

Description of nymphs and ontogenetic morphometry of Triatoma ryckmani Zeledón & Ponce, 1972 (Hemiptera: Heteroptera: Reduviidae: Triatominae)

EntomoBrasilis, 2020
Triatoma ryckmani Zeledón & Ponce, 1972 is a species found in sylvatic habitat at Central America. Considered rare in the past and poorly studied, nowadays can be found inside houses with potential of dispersal and colonization.

The Contribution of Entomological Surveillance to the Control of Chagas Disease in Endemic Regions: An Integrative Literature Review

Tropical Medicine &International Health, Volume 31, Issue 7, Page 832-842, July 2026.
ABSTRACT Chagas disease remains a significant public health challenge in various endemic regions of Latin America. The persistence of vector‐borne transmission highlights the complexity of the issue and the limitations of traditional strategies. In this context, entomological surveillance plays a strategic and multifaceted role, not only in the early ...

TNF‐α partially modulates the endothelial dysfunction during the acute phase of Trypanosoma cruzi infection

British Journal of Pharmacology, Volume 183, Issue 10, Page 2256-2272, May 2026.
Background and Purpose Whereas the effects of Trypanosoma cruzi (T. cruzi) infection are well‐characterised in the heart, its impact on the vasculature has received little attention. In this study, we investigated the effects of acute and chronic T. cruzi infection on vascular responsiveness and the underlying mechanisms.

Trends in taxonomy of Triatomini (Hemiptera, Reduviidae, Triatominae): reproductive compatibility reinforces the synonymization of Meccus Stål, 1859 with Triatoma Laporte, 1832

Parasites & Vectors, 2021
Meccus' taxonomy has been quite complex since the first species of this genus was described by Burmeister in 1835 as Conorhinus phyllosoma. In 1859 the species was transferred to the genus Meccus and in 1930 to Triatoma. However, in the twentieth century,

Trapping sylvatic Triatominae (Reduviidae) in hollow trees [PDF]

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1999
This work reports the trial of a very simple trapping system (comprising small plastic bottles (9 X 6 cm) covered with double­ coated adhesive tape and containing a mouse as bait ) to collect all instars of triatomines in hollow trees, a favourable ecotope for many triatomine species including T. sordida, T. guasayana, and T. infestans 'dark morphs'

Endemism and Conservation of Hemiptera on the Qinghai‐Tibetan Plateau

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Endemism patterns of Hemiptera on the Qinghai‐Tibetan Plateau (QTP) are mainly driven by historical climate change. Existing protected areas do not sufficiently cover endemism hotspots. ABSTRACT The Qinghai‐Tibetan Plateau is essential for the maintenance of global biodiversity.

Research needs for Chagas disease prevention.

, 2010
We present an overview of the two main strategies for the primary (vector control) and secondary (patient care) prevention of Chagas disease (CD). We identify major advances, knowledge gaps, and key research needs in both areas.
