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

Daily Variations in the Expression of Genes Related to Insecticide Resistance in the Chagas Disease Vector Triatoma infestans (Hemiptera: Reduviidae). [PDF]

Am J Trop Med Hyg, 2019
Pyrethroid resistance has been detected in Triatoma infestans, which in part has been attributed to increased oxidative metabolism of the insecticide by cytochrome P450s. Nicotinamide adenine dinucleotide phosphate (NADPH) cytochrome P450 reductase (CPR)

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 ...

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.

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.

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.

Using axenic and gnotobiotic insects to examine the role of different microbes on the development and reproduction of the kissing bug Rhodnius prolixus (Hemiptera: Reduviidae)

Molecular Ecology, Volume 32, Issue 4, Page 920-935, February 2023., 2023
Abstract Kissing bugs (Hempitera: Reduviidae) are obligately and exclusively blood feeding insects. Vertebrate blood is thought to provide insufficient B vitamins to insects, which rely on symbiotic relationships with bacteria that provision these nutrients.
