Taxonomic and systematic analysis among triatomine bug species (Hemiptera, Reduviidae) from colonies of the Special Health Service of Araraquara (SESA), inferred from 16S rDNA mitocondrial sequences [PDF]

, 2008
Foram analisadas seqüências de nucleotídeos do gene 16S do rDNA mitocondrial em 14 populações de triatomíneos mantidos em colônias no insetário SESA de Araraquara- SP, comparando-as com seqüências do mesmo gene disponíveis no GenBank.

A new piece in the repeatome puzzle of Triatominae bugs: The analysis of Triatoma rubrofasciata reveals the role of satellite DNAs in the karyotypic evolution of distinct lineages

Insect Molecular Biology, Volume 34, Issue 6, Page 917-928, December 2025.
Satellite DNAs comprise the major component of the Triatoma rubrofasciata repeatome, highlighting their central role in genome composition and architecture. Satellite DNA families show recent amplification in heterochromatin and older, more divergent satellite DNAs located in euchromatin, indicating distinct evolutionary histories.

Potential geographic displacement of Chagas disease vectors under climate change

Medical and Veterinary Entomology, Volume 39, Issue 4, Page 709-717, December 2025.
As a result of modelling the potential distribution of 55 triatomine species in the Neotropical region, with climate change projected for up to 2050, we found no significant changes. With climate change projected for up to 2080 in the Neotropical region, we see a significant potential for the migration of 55 species of triatomines towards the Amazon ...

Metaciclogênese do Trypanosoma cruzi como parâmetro de interação do parasita com o triatomíneo vetor

Revista da Sociedade Brasileira de Medicina Tropical, 1997
Triatoma infestans infectados por três amostras do Trypanosoma cruzi permitiram observar: 1) variabilidade numérica de metacíclicos obtidos de cada amostra após diferentes períodos de infecção; 2) diferenças na perda da infecção de acordo com a amostra ...

Canine Trypanosoma cruzi infection in the Bolivian Chaco [PDF]

, 2018
A cross-sectional study on Trypanosoma cruzi was carried out in 2013 to evaluate the role of dogs as possible source of infection for humans in two rural communities of the highly endemic Bolivian Chaco (Bartolo, Chuquisaca Department, n = 57 dogs; and ...

Effects of the alarm pheromone on Triatoma pallidipennis behaviour

Physiological Entomology, Volume 50, Issue 4, Page 374-387, December 2025.
T. pallidipennis performs behavioural acts in response to volatiles emitted by mechanically disturbed conspecifics. T. pallidipennis shows a repellent response when exposed to volatiles emitted by mechanically disturbed conspecifics. Isobutyric and propanoic acids can be used as repellents of T. pallidipennis. Abstract Adults of some Triatomine species,

Modelling the potential geographic distribution of triatomines infected by Triatoma virus in the southern cone of South America [PDF]

, 2015
Background: Triatoma virus (TrV) is the only entomopathogenous virus identified in triatomines. We estimated the potential geographic distribution of triatomine species naturally infected by TrV, using remotely sensed and meteorological environmental ...

Biotic Assembly of the Species of Triatomini (Hemiptera: Reduviidae: Triatominae) in the Mexican and South American Transition Zones

Journal of Biogeography, Volume 52, Issue 10, October 2025.
ABSTRACT Aim To infer the biogeographic history of the Triatomini by evaluating how their species became part of the biogeographic transition zones of the New World. This group of blood‐feeding insects includes key vectors of Chagas disease. Understanding their dispersal and diversification over geological time may help elucidate the temporal dynamics ...
