Biological Control of the Chagas Disease Vector Triatoma infestans with the Entomopathogenic Fungus Beauveria bassiana Combined with an Aggregation Cue: Field, Laboratory and Mathematical Modeling Assessment [PDF]

, 2015
Background: Current Chagas disease vector control strategies, based on chemical insecticide spraying, are growingly threatened by the emergence of pyrethroid-resistant Triatoma infestans populations in the Gran Chaco region of South America. Methodology

Pyrethroid-Resistant and Susceptible Triatoma infestans (Klug, 1834) (Hemiptera, Triatominae): Analysis of Their Vectorial Characteristics by Metacyclogenesis, Feeding/Defecation Patterns, and Parasite Load

Parasitologia, 2022
Populations of Triatomas infestans with different susceptibility to pyrethroid insecticides were reported to have distinct evolutionary and epidemiological characteristics.

Gene discovery in Triatoma infestans [PDF]

Parasites & Vectors, 2011
AbstractBackgroundTriatoma infestansis the most relevant vector of Chagas disease in the southern cone of South America. Since its genome has not yet been studied, sequencing of Expressed Sequence Tags (ESTs) is one of the most powerful tools for efficiently identifying large numbers of expressed genes in this insect vector.ResultsIn this work, we ...

Improving houses in the Bolivian Chaco increases effectiveness of residual insecticide spraying against infestation with Triatoma infestans, vector of Chagas disease

Tropical medicine & international health, 2021
Failure to control domestic Triatoma infestans in the Chaco is attributed to vulnerable adobe construction, which provides vector refuges and diminishes insecticide contact.

The spread of satellite DNAs in euchromatin and insights into the multiple sex chromosome evolution in Hemiptera revealed by repeatome analysis of the bug Oxycarenus hyalinipennis

Insect Molecular Biology, Volume 32, Issue 6, Page 725-737, December 2023., 2023
The genomic analysis revealed a male‐biased abundance of satellite DNAs (satDNAs) in the bug Oxycarenus hyalinipennis. The complementary chromosomal analysis by fluorescence in situ hybridization supported the notion of satDNA enrichment on the Y chromosome of the species.

Residual effect of lambdacyhalothrin on Triatoma infestans [PDF]

Memórias do Instituto Oswaldo Cruz, 1995
Insecticidal residual effect and triatomine infestation rates in houses of a community fumigated with lambdcyhalothrin (Icon) are reported. No mortality was observed in 5th-instar Triatoma infestans nymphs in 72-hr exposure test on three different surfaces, one month after fumigation for a dose of 31.5 mg am/m2.

Comparative morphology of serotonin‐immunoreactive neurons innervating the central complex in the brain of dicondylian insects

Journal of Comparative Neurology, Volume 531, Issue 14, Page 1482-1508, October 2023., 2023
The central complex is an insect brain area controlling goal‐directed orientation. Comparative analysis of insect species ranging from firebrats to flies reveals two bilateral pairs of serotonin‐immunoreactive neurons innervating the central complex in all neopteran species and two additional pairs of neurons in flies and butterflies.

Bacteriolytic activity in saliva of the hematophagous Triatoma infestans (Reduviidae) and novel characterization and expression site of a third lysozyme

Archives of Insect Biochemistry and Physiology, Volume 113, Issue 3, July 2023., 2023
Bacteriolytic activity after zymography of saliva obtained from unfed nymphs or 7 days after feeding and after an incubation at pH 4 and pH 6, followed by staining and additional incubation in water. Molecular masses of marker proteins are displayed on the left.

Comparison of feeding and defecation patterns between fifth-instar nymphs of Triatoma patagonica (Del Ponte, 1929) and Triatoma infestans (Klug, 1934) under laboratory conditions Comparação dos padrões alimentar e de defecação em ninfas de quinto estádio de Triatoma patagonica (Del Ponte, 1929) e Triatoma infestans (Klug, 1934), em condições de laboratório

Revista da Sociedade Brasileira de Medicina Tropical, 2008
Among the vectors of Chagas disease, Triatoma patagonica is a species in the process of adaptation to the human environment. However, its vector competence is not well known.
