Estudo comparado do ciclo evolutivo de triatomíneos a duas temperaturas Comparison of life cycles of triatominae according to changes in temperature

Memorias do Instituto Oswaldo Cruz, 1989
We studied the life cicle of several triatominae species: Dipetalogaster maximus (Uhler, 1894); Panstrongylus herreri Wygodzinsky, 1948; Panstrongylus megistus (Burmeister, 1835); Rhodnius ecuadoriensis Lent & Leon, 1958; Rhodnius nasutus Stal, 1859 ...

Trends in Taxonomy of the Rhodniini Tribe (Hemiptera, Triatominae): Reproductive Incompatibility between Rhodnius neglectus Lent, 1954 and Psammolestes spp. Confirms the Generic Status of Psammolestes Bergroth, 1911

Diversity, 2022
The tribe Rhodniini is a monophyletic group composed of 24 species grouped in two genera: Rhodnius and Psammolestes. Rhodnius is a paraphyletic genus formed by 21 species.

Rhodnius prolixus: Identification of missing components of the IMD immune signaling pathway and functional characterization of its role in eliminating bacteria

PLoS ONE, 2019
The innate immune system in insects is regulated by specific signalling pathways. Most immune related pathways were identified and characterized in holometabolous insects such as Drosophila melanogaster, and it was assumed they would be highly conserved ...

A rhamnose-binding lectin from Rhodnius prolixus and the impact of its silencing on gut bacterial microbiota and Trypanosoma cruzi.

Developmental and Comparative Immunology, 2020
Lectins are ubiquitous proteins involved in the immune defenses of different organisms and mainly responsible for non-self-recognition and agglutination reactions. This work describes molecular and biological characterization of a rhamnose-binding lectin

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.

Taxonomical over splitting in the Rhodnius prolixus (Insecta: Hemiptera: Reduviidae) clade: Are R. taquarussuensis (da Rosa et al., 2017) and R. neglectus (Lent, 1954) the same species?

PLoS ONE, 2019
The use of subtle features as species diagnostic traits in taxa with high morphological similarity sometimes fails in discriminating intraspecific variation from interspecific differences, leading to an incorrect species delimitation.

Unravelling the biochemical aspects of the interaction between ticks and Leishmania using a tick cell line

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 350-359, June 2026.
Leishmania infantum propagated in IDE8 tick cell line in vitro. L. infantum reduces tick cell viability and induces reactive oxygen species production. Lipidic profile of IDE8 tick cell line is altered during Leishmania infection. Abstract Leishmaniasis comprises a group of vector‐borne neglected tropical diseases caused by species of the obligatory ...

Effects of proallatotoxins (precocenes) on the development and reproduction of Rhodnius prolixus: some data

Memorias do Instituto Oswaldo Cruz, 1991
Proallatotoxins, and particularly preconcenes, are exceptionally promising models for studying Rhodnius prolixus physiology and for comparison with other natural compounds with anti-hormonal activities.

Conkazal‐M1 from the MKAVA family of conotoxins: A dual‐function protease inhibitor and neuroactive peptide

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Marine cone snails produce a diverse array of bioactive peptides, known as conotoxins, in their venom. Given their high target potency and specificity, conotoxins are attractive compounds for the development of precision research tools and pharmacological agents.
