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.

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.

Trypanosomiasis vector control in Africa and Latin America. [PDF]

, 2008
Vectors of trypanosomiasis - tsetse (Glossinidae) in Africa, kissing-bugs (Triatominae) in Latin America - are very different insects but share demographic characteristics that render them highly vulnerable to available control methods.

Taxonomy, Evolution, and Biogeography of the Rhodniini Tribe (Hemiptera: Reduviidae)

Diversity, 2020
The Triatominae subfamily includes 151 extant and three fossil species. Several species can transmit the protozoan parasite Trypanosoma cruzi, the causative agent of Chagas disease, significantly impacting public health in Latin American countries.

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.

Modeling disease vector occurrence when detection is imperfect: infestation of Amazonian palm trees by triatomine bugs at three spatial scales. [PDF]

, 2010
BACKGROUND: Failure to detect a disease agent or vector where it actually occurs constitutes a serious drawback in epidemiology. In the pervasive situation where no sampling technique is perfect, the explicit analytical treatment of detection failure ...

Successional and native forests predict the occurrence and infection status of Chagas disease vectors in Panama

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Findings here show that successional forest predicts greater kissing bug infestation risk in palm trees, whereas native forest predicts lower kissing bug occurrence but greater infection with T. cruzi. These insights can guide land use planning towards vegetation management practices that help minimize T. cruzi transmission risks for rural communities.
