Chromosome homogeneity in populations of Triatoma brasiliensis Neiva 1911 (Hemiptera - Reduviidae - Triatominae)

Cadernos de Saúde Pública
Triatoma brasiliensis is the most important vector of Chagas disease in the semiarid zone of the Northeast of Brazil. Several authors have reported the occurrence of four chromatic patterns with morphological, ecological, and genetic differences.

Does Triatoma brasiliensis occupy the same environmental niche space as Triatoma melanica? [PDF]

Parasit Vectors, 2015
Triatomines (Hemiptera, Reduviidae) are vectors of Trypanosoma cruzi, the causative agent of Chagas disease, one of the most important vector-borne diseases in Latin America. This study compares the environmental niche spaces of Triatoma brasiliensis and Triatoma melanica using ecological niche modelling and reports findings on DNA barcoding and wing ...

Reproductive Biology of Triatoma brasiliensis (Hemiptera, Triatominae) During the Imaginal Molt. [PDF]

Am J Trop Med Hyg, 2016
The triatomines are vectors of the protozoan Trypanosoma cruzi, etiologic agent of Chagas disease. These insects are sexually active after the imaginal molt. Some aspects have been studied in Triatoma brasiliensis during the imaginal molt, such as autogeny in virgin females and the relationship between blood ingestion by fifth instar nymph and the ...

Evolutionary ecology of Chagas disease; what do we know and what do we need?

Evolutionary Applications, Volume 11, Issue 4, Page 470-487, April 2018., 2018
Abstract The aetiological agent of Chagas disease, Trypanosoma cruzi, is a key human pathogen afflicting most populations of Latin America. This vectorborne parasite is transmitted by haematophageous triatomines, whose control by large‐scale insecticide spraying has been the main strategy to limit the impact of the disease for over 25 years.
