A ‘vigilance unit’ for households subject to triatomine control
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1982Abstract An inexpensive ‘vigilance unit’ consisting of a cardboard box and attached plastic bag is described. This is utilized to provide two ways of detecting residual triatomine bugs present after an insecticide control programme in Brazil. How well it works will depend on the householders' enthusiasm to participate in the vigilance measures ...

Interactions of Trypanosoma cruzi and Triatomines
2011Triatomine bugs are vectors of Trypanosoma cruzi, the etiologic agent of Chagas disease in Latin America. The flagellate colonizes the intestinal tract of the insect, especially the rectum. T. cruzi changes the composition of amino acids and proteins/peptides in the rectum and affects the intestinal innate immune homeostasis.

Genital morphology and copulatory behavior in triatomine bugs (Reduviidae: Triatominae).
Arthropod structure & development, 2019Triatomines (Heteroptera: Reduviidae) include around 139 species, widely known as vectors of Chagas disease. Our aim is to review the existing knowledge of the genital morphology and sexual behavior and provide some functional analysis of these traits in

Cleptohaematophagy of the Triatomine bug Belminus herreri
Medical and Veterinary Entomology, 2000Summary The Triatomine bug Belminus herreri , previously known only from Panama, is reported for the first time from Colombia. Three adult B. herreri were collected from a chicken coop and a viable egg was found on a

Triatomines as Experimental Vectors of Trypanosomes of Asian Monkeys
The American Journal of Tropical Medicine and Hygiene, 1978Systematic surveys of the wild macaques of South Asia by blood culture resulted in the discovery that trypanosomiasis is enzootic in the simians of Indonesia, Malaysia, India, and Thailand. The isolates obtained differ in morphology, metabolism, and ability to multiply in arthropods.

Infection of triatomines with Trypanosoma cruzi
1997The scientist who discovered American trypanosomiasis (Chagas’ disease), Carlos Chagas, not only wisely recognized the disease as a clinical entity, but also identified its causative agent (Trypanosoma cruzi) and its haematophagous (triatomine) insect vector (Chagas, 1909).

Care and maintenance of triatomine colonies
1997The family Reduviidae, subfamily Triatominae, indudes more than 110 species, several of which are vectors of Trypanosoma cruzi, the causative agent of Chagas’ disease or American trypanosomiasis. Triatomines are common in the Americas, from the southern USA throughout Latin America, south to Patagonia.

Density-dependent perception of triatomine bug bites
Annals of Tropical Medicine & Parasitology, 1986Pots containing different densities of Rhodnius prolixus were strapped on to the upper and lower arms and legs of six human volunteers. Analysis of the volunteers' perception of the bugs' probing activity showed a clear linear trend of perception according to bug density. Comparison with other results suggests that in humans as well as other vertebrate

Triatomines as Vectors of American Trypanosomiasis
2012Triatomine bugs are the biggest blood-sucking insects, with adults up to 41 mm long. They are well adapted to hematophagy, possessing fine mouthparts to ingest blood from the capillaries of the warm-blooded hosts. Hematophagy is supported by the salivary glands, a “chemical factory” producing hundreds of compounds, some of them acting as local ...

Differences in competitive ability for the occupancy of shelters in triatomines
Medical and Veterinary Entomology, 2017Abstract Triatomines (Hemiptera: Reduviidae: Triatominae) are nocturnal blood‐sucking insects. During daylight hours they remain in an akinetic state inside their shelters, whereas at dusk they become active and move outside. When they are outside their shelters during the photophase, triatomines are vulnerable to
