Triatoma infestans, to be or not to be autogenic?

Acta Tropica, 2023
Autogeny, the ability to develop eggs without a meal in the adult stage, has been described in several groups of arthropods, especially hematophagous Diptera Nematocera. In obligate hematophagous hemimetabolous insects that feed on blood in all their instars, such as Triatominae, this concept gives rise to species with apparently facultative autogeny ...

Degradation of serum proteins in Triatoma infestans

Experimental Parasitology, 1976
It has been previously described (Perassi 1972, 1973)that no serum proteins from the animal on which the insects were fed can be detected in the insects' hemolymph of either male or female Triatoma infestans. In other words, the absorption of the proteins does not take place from the gut content to the hemolymph.

The occurrence of arachidonic acid in Triatoma infestans

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1987
1. Gas-liquid chromatography and mass spectrometry were used to verify the presence of arachidonic acid (20:4 omega 6) in adult male and female organs of the blood-suckling bug Triatoma infestans. Fat body, gonad and head lipids were analyzed. 2. Male gonads contained the highest percentage of phospholipids and the highest percentage of arachidonic ...

Triatoma Virus Pathogenicity in Laboratory Colonies of Triatoma infestans (Hemiptera: Reduviidae)

Journal of Medical Entomology, 1997
In 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.

Nervous system of Triatoma infestans

Journal of Morphology, 1994
AbstractThe 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).

Population dynamics and control of Triatoma infestans

Medical and Veterinary Entomology, 1992
Abstract. 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.

Similarity of the patterns of sensilla on the antennae of Triatoma melanosoma and Triatoma infestans

Annals of Tropical Medicine & Parasitology, 2001
The 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, 1972
Abstract 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, 1976
The 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.
