Revisiting the chromosomal diversification of the genus rhodnius (Stål, 1859) (Hemiptera, Triatominae)

open access: yes, 2021
Although all triatomines are considered as potential vectors of the Chagas disease, the Triatoma, Panstrongylus, and Rhodnius genera are the most important from the epidemiological point of view.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Aspects of classification of Hemiptera hemocytes from six triatomine species

open access: yesMemorias do Instituto Oswaldo Cruz, 1991
The objective of this work was to characterize, and compare different morphological types of hemocytes of Rhodnius prolixus, Rhodnius, Rhodnius neglectus, Triatoma infestans, Panstrongylus megistus, and Dipetalogaster maximus.

First report of Rhodnius stali Lent, Jurberg & Galvão, 1993 (Hemiptera: Reduviidae: Triatominae), vector of Trypanosoma cruzi (TcI) and Trypanosoma rangeli (TrA), in Rondônia, Southwestern Brazilian Amazonia

open access: yesHeliyon, 2023
Triatomines are hematophagous insects of epidemiological importance as they are vectors of Chagas disease. The first report of Rhodnius stali Lent, Jurberg & Galvão, 1993 in Rondônia, Brazil, is described.

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus

open access: yesInsect Science, EarlyView.
Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

A panel of ten microsatellite loci for the Chagas disease vector Rhodnius prolixus (Hemiptera: Reduviidae). [PDF]

open access: yes, 2008
Rhodnius prolixus is the main vector of Chagas disease in Venezuela, where it is found colonising rural housing consisting of unplastered adobe walls with palm and/or metal roofs.

Karyotype of Rhodnius montenegrensis (Hemiptera, Triatominae)

open access: yesGenetics and Molecular Research, 2015
The Triatominae subfamily comprises 6 tribes. The tribe Rhodniini comprises 2 genera and 22 nominal species. Rhodnius montenegrensis (Hemiptera, Triatominae) was recently described as evolutionarily related to R. robustus. Therefore, in order to contribute to karyosystematic study of the tribe Rhodniini, this report describes the number of chromosomes ...

Entomological surveillance of Trypanosoma cruzi vectors in Rio Grande do Norte, Brazil

open access: yesMedical and Veterinary Entomology, EarlyView.
Discontinuous entomological surveillance and persistent infestation by triatomines highlight the risk of Trypanosoma cruzi transmission. The diversity of triatomine species in the peridomicile shows the potential for colonization into the home. The wide distribution of Triatoma brasiliensis and Triatoma pseudomaculata accompanies high rates of ...

Assessment of the Performance of Indirect Immunofluorescence Assay for Chagas Disease in Dogs Using a Reference Panel of Four Chimeric Proteins

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
We evaluated the performance of an indirect immunofluorescence (IIF) assay for detecting anti‐Trypanosoma cruzi IgG in dogs using four chimeric IBMP antigens and latent class analysis. The IIF assay showed suboptimal sensitivity and overall accuracy compared to ELISA and LCA‐based methods.
