Nuclear rDNA-based molecular clock of the evolution of triatominae (Hemiptera: reduviidae), vectors of Chagas disease.
Inferred chronological data about the evolution of Triatominae fit well with current hypotheses on their evolutionary histories, but suggest reconsideration of the current taxonomy of North American species complexes.
Phylogeography and Genetic Variation of Triatoma dimidiata, the Main Chagas Disease Vector in Central America, and Its Position within the Genus Triatoma
The distinction between the five different taxa furnishes a new frame for future analyses of the different vector transmission capacities and epidemiological characteristics of Chagas disease, and indicates that T. dimidiata will offer problems for control, although dwelling insecticide spraying might be successful against introduced populations in Ecuador.
The ITS-2 of the nuclear rDNA as a molecular marker for populations, species, and phylogenetic relationships in Triatominae (Hemiptera: Reduviidae), vectors of Chagas disease.
Phylogenetic trees support an old divergence between South American and North-Central American Triatomini and query the validity of some genera and the very low sequence variation between species of the phyllosoma complex suggests that subspecific ranking would be more appropriate.

Genomic Changes of Chagas Disease Vector, South America
This study analyzed the main karyologic changes that have occurred during the dispersion of Triatoma infestans and proposed that heterochromatin and DNA variation mainly reflected adaptive genomic changes that contribute to the ability of T. infestan to survive, reproduce, and disperse in different environments.
Isozyme evidence of lack of speciation between wild and domestic Triatoma infestans (Heteroptera: Reduviidae) in Bolivia.
Wild and domestic Triatoma infestans from the Cochabamba region of Bolivia were virtually identical at 19 gene loci coding for enzymes; no allele was distinctive of either the wild or the domestic populations, and this supports the hypothesis that there is no speciation between wild and domestic T. infestants.
Theories on the evolution of Rhodnius
Current knowledge about the sequence of events leading to the domestication of species of Rhodnius that are important vectors of Chagas disease in the Andean pact and Central American countries is reviewed.
Mitochondrial DNA sequence variation among triatomine vectors of Chagas' disease.
In a preliminary analysis of the mitochondrial large subunit ribosomal RNA (mtlsurRNA) and cytochrome B (mtCytB) genes, DNA sequencing was used to study species identification and phylogeny and produced similar results that were generally consistent with the accepted taxonomy of the subfamily.
The process of domestication in Triatominae.
The process of domestication in Triatominae is not only a historical event, but may be a generalised current trend within the subfamily (cf. Diotaiuti 1997).
