Blood Digestion in Triatomine Insects

2021
Triatomine insects had a fundamental role in the establishment of essential concepts of insect physiology, especially thanks to the use of Rhodnius prolixus as a model for basic research in the last century. The major unique feature that made triatomines excellent models is their strictly hematophagous way of life, as molting in nymph stages and ...

Development of an operational trap for collection, killing, and preservation of triatomines (Hemiptera: Reduviidae): the kissing bug kill trap

Journal of medical entomology
Surveillance of triatomines or kissing bugs (Hemiptera: Reduviidae: Triatominae), the insect vectors of Trypanosoma cruzi, a Chagas disease agent, is hindered by the lack of an effective trap.To develop a kissing bug trap, we made iterative improvements ...

Density-dependent perception of triatomine bug bites

Annals of Tropical Medicine & Parasitology, 1986
Pots 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

Survival of Arboviruses in Trypanosome-Infected Triatomines

The American Journal of Tropical Medicine and Hygiene, 1977
The potential of triatomines to maintain arboviruses was demonstrated by the ability of Rhodinius prolixus with experimentally punctured abdomen to harbor Venezuelan equine encephalitis (VEE) virus for at least 4 months and St. Louis encephalitis virus for 1 month.

Occurrence of domestic and intrusive triatomines (Hemiptera: Reduviidae) in sylvatic habitats of the temperate Monte Desert ecoregion of Argentina.

Acta Tropica, 2019
The eco-epidemiology of Triatominae and Trypanosoma cruzi transmission has been little studied in the Argentinean Monte ecoregion. Herein, we provide a comprehensive description of domestic and intrusive triatomines to evaluate the risk of reinfestation ...

Cleptohaematophagy of the Triatomine bug Belminus herreri

Medical and Veterinary Entomology, 2000
Summary 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

Interactions of Trypanosoma cruzi and Triatomines

2011
Triatomine 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.

Sound production in some triatomine bugs

Physiological Entomology, 1977
ABSTRACT. Adults of five species of Triatominae were found to stridulate when handled: Triatoma protracta, T. lenti, T. infestans, Panstrongylus megistus and Dipetalogaster maximus.

Simplified membrane feeding of bloodsucking triatomines (Hemiptera: Reduviidae)

Acta Tropica, 2017
Laboratory-reared hematophagous triatomines that are the main vectors of Chagas disease are generally fed on small vertebrates or on blood-filled membrane devices. Such devices allow a large-scale rearing of these vectors without sacrificing host animals but are almost always expensive, fragile, not easily purchased, and usually difficult to use ...

Care and maintenance of triatomine colonies

1997
The 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.
