Chagas' disease in the Amazon Basin: V. Periurban palms as habitats of Rhodnius robustus and Rhodnius pictipes - triatomine vectors of Chagas' disease

Memorias do Instituto Oswaldo Cruz, 1983
Trypanosoma cruzi infected Rhodnius robustus and/or Rhodnius pictipes were commonly found, in large numbers, in the Brazilian Amazonian palms Maximiliana regia ("inajá"), Acrocomia sclerocarpa ("mucajá") and Orbignya speciosa ("babaçu").

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,

Interacción tripanosoma-vector-vertebrado y su relación con la sistemática y la epidemiología de la tripanosomiasis americana

Biomédica: revista del Instituto Nacional de Salud, 2007
Introducción. Trypanosoma rangeli es la segunda especie de tripanosoma que infecta al hombre en América Latina. Se ha observado variabilidad en las características biológicas, bioquímicas y moleculares en diferentes aislamientos de este parásito ...

Karyotype of Rhodnius montenegrensis (Hemiptera, Triatominae)

Genetics 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 ...

Effect of photoperiod and host distribution on the horizontal transmission of Isaria fumosorosea (Hypocreales: Cordycipitaceae) in greenhouse whitefly assessed using a novel model bioassay [PDF]

, 2010
A model bioassay was used to evaluate the epizootic potential and determine the horizontal transmission efficiency of Isaria fumosorosea Trinidadian strains against Trialeurodes vaporariorum pharate adults under optimum conditions (25±0.5°C, ~100% RH ...

Characterization of Triacylglycerol Dynamics and Lipid Metabolism in the Beetle Tribolium castaneum

Archives of Insect Biochemistry and Physiology, Volume 120, Issue 3, November 2025.
Tribolium castaneum larvae accumulate triacylglycerol (TAG) during development, while adults rapidly deplete reserves post‐emergence. Under starvation, beetles prioritize protein catabolism over lipid mobilization, despite increased expression of lipolysis genes, revealing stage‐specific metabolic adaptations in this model insect.

Identifying Health Centers in Honduras Infested with Rhodnius Prolixus Using the Seroprevalence of Chagas Disease in Children Younger than 13 Years. [PDF]

, 2005
The objective of this study is to determine if a Chagas disease protocol starting with a serological survey is as reliable at identifying insect-infested areas as one using the gold standard entomological survey.

Evaluation of two candidate molecules—TCTP and cecropin—on the establishment of Trypanosoma brucei gambiense into the gut of Glossina palpalis gambiensis

Insect Science, Volume 32, Issue 5, Page 1747-1760, October 2025.
This study investigates the potential of enhancing the resistance of Glossina palpalis gambiensis to Trypanosoma brucei gambiense to mitigate the transmission of Human African Trypanosomiasis. We successfully cloned genes encoding proteins of interest in Sodalis strains, resulting in recombinant Sodalis (recSodalis) that were micro‐injected into the L3

Symbiont-mediated RNA interference in insects [PDF]

, 2016
RNA interference (RNAi) methods for insects are often limited by problems with double-stranded (ds) RNA delivery, which restricts reverse genetics studies and the development of RNAi-based biocides. We therefore delegated to insect symbiotic bacteria the

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

Insect Molecular Biology, Volume 34, Issue 5, Page 632-644, October 2025.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce
