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.

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.

Triatomine physiology in the context of trypanosome infection

Journal of Insect Physiology, 2017
Triatomines are hematophagous insects that feed on the blood of vertebrates from different taxa, but can occasionally also take fluids from invertebrate hosts, including other insects. During the blood ingestion process, these insects can acquire diverse parasites that can later be transmitted to susceptible vertebrates if they complete their ...

Triatomines as Vectors of American Trypanosomiasis

2012
Triatomine 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 ...

Amines from vertebrates guide triatomine bugs to resources

Journal of Insect Physiology, 2014
Most triatomine bugs (Heteroptera: Reduviidae) are nest-living insects that require vertebrate blood or invertebrate haemolymph to complete their life cycle. Vertebrates accumulate excretory products in or near their nesting sites and we hypothesize that triatomines use emanations from such host wastes when searching for resources.
