Triatoma Virus Pathogenicity in Laboratory Colonies of Triatoma infestans (Hemiptera: Reduviidae)
Journal of Medical Entomology, 1997In a survey of wild populations of Triatoma infestans (Klug) in Argentina, 10% were infected with Triatoma virus (TrV). The virus also was detected in a laboratory colony 18 mo after being established, with infection rates up to 100%. Mortality rate was 97.6% in nymphs and the molting process was inhibited, thereby increasing development time.

Population dynamics and control of Triatoma infestans
Medical and Veterinary Entomology, 1992Abstract. Analysis of field populations of Triatoma infestans (Hemiptera: Reduviidae), after a 3‐year study, shows that population growth rate is affected by both density‐dependent and density‐independent mortality.

Nervous system of Triatoma infestans
Journal of Morphology, 1994AbstractThe anatomy of the adult nervous system of the haematophagous bug Triatoma infestans has been studied by means of dissections and histology. The central nervous system comprises three nervous masses: the brain + suboesophageal ganglion, the prothoracic ganglion, and the posterior fused ganglion (meso + metathoracic + abdominal ganglia).

Similarity of the patterns of sensilla on the antennae of Triatoma melanosoma and Triatoma infestans
Annals of Tropical Medicine & Parasitology, 2001The patterns of sensilla on the antennae of sylvatic Triatoma melanosoma Lent, Jurberg, Galvao and Carcavallo 1994 were compared with those of three samples of Triatoma infestans (Klug 1834) - one of domestic populations in Paraguay, Bolivia, Argentina and Chile, one of the sylvatic 'dark morph' from the Bolivian Chaco, and one from sylvatic sites in ...

Antigenic components in Triatoma infestans haemolymph
Journal of Insect Physiology, 1972Abstract Immunoelectrophoretic experiments were made of the antigenic composition of Triatoma infestans haemolymph, taking instar and feeding into consideration. Haemolymph from adult male insects against antiserum to haemolymph of T. infestans, revealed between 14 and 17 antigenic components.

The intestine of Triatoma infestans. I. Cytology of the midgut
Journal of Ultrastructure Research, 1976The midgut of starved Triatoma infestans was studied by light and electron microscopy. The apical border of the intestinal cells shows microvilli in a regular array and a peculiar peritrophic membrane that forms tube like compartments around and upon the microvilli. The other cellular components are similar to those found in other hematophagus insects.

Kinetics of expression of the salivary apyrases in Triatoma infestans
Insect Biochemistry and Molecular Biology, 2004Apyrases are nucleoside triphosphate-diphosphohydrolases that remove Pi from ATP and ADP. The blood feeding reduviid Triatoma infestans, which transmits the Trypanosoma cruzi agent of Chagas disease to animals and man, presents in its salivary glands five apyrases with molecular masses of 88, 82, 79, 68 and 67 kDa.

Field experiments of dispersive flight by Triatoma infestans
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1981Using marked male Triatoma infestans allowed to escape and fly on a little-used airport in Brazil and salt flats in Argentina, 33 of 169 flew in the former and 28 of 528 in the latter experiment. Many of the bugs which flew had been classed as poorly fed. The proportion of bugs which flew was in reasonable agreement with predictions based on laboratory

Isolation and characterization of the haemolymph lipoproteins of Triatoma infestans
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19821. Three lipoproteins differing in hydrated densities were isolated by ultracentrifugal procedures from the haemolymph of adult and fasted Triatoma infestans. 2. They are the high density lipoprotein HDL (d = 1.115-1.152) and the two very high density lipoproteins VHDL-I (d = 1.190-1.231) and VHDL-II (d = 1.245-1.260).

Repellency of deet to nymphs of Triatoma infestans
Medical and Veterinary Entomology, 2000Summary The repellency of N,N‐diethyl‐3‐methylbenzamide (deet) to Triatoma infestans (Klug) (Hemiptera: Reduviidae) was evaluated using third‐instar nymphs and a video tracking technique.
