“…DNA markers such as genomic or mitochondrial DNA sequence features and DNA microsatellites are highly useful for analyzing genetic variations among various triatomine taxa (Garcia and Powell, 1998;Lyman et al, 1999;Monteiro et al, 2000;Dotson and Beard, 2001;Marcilla et al, 2001;Monteiro et al, 2001). While mitochondrial DNA sequence polymorphism is very useful for distinguishing differences among similar species and among populations of the same species from different geographic locations Monteiro et al, 2001), it lacks the sensitivity to detect very subtle differences that frequently exist among very recently diverged populations.…”

Contribución de los autores:Óscar Quirós-Gómez: concepción y diseño del estudio, recolección y resumen de información bibliográfica y escritura del manuscrito Nicolás Jaramillo: recolección de información bibliográfica y escritura del manuscrito Víctor M. Angulo: análisis e interpretación de datos Gabriel Parra-Henao: concepción y diseño del estudio, análisis e interpretación de datos y escritura del manuscrito Todos los autores participaron en la revisión del manuscrito. Triatoma dimidiata es un importante vector de la enfermedad de Chagas en Centroamérica y en los países del norte de Suramérica. En Colombia, tiene una amplia distribución y su presencia se ha reportado en 14 departamentos de las regiones Andina, Caribe, de los Llanos Orientales y del Alto Magdalena, en las cuales ocupa diferentes ecótopos naturales y artificiales. La especie está clasificada como secundaria para la transmisión de Trypanosoma cruzi; sin embargo, su presencia en el ambiente silvestre, peridoméstico y doméstico en la región Andina, y su capacidad de movilizarse entre ellos, le han permitido escapar al control basado en la aspersión con piretroides y ello resalta su importancia en el mantenimiento de la transmisión del parásito debido a la potencial reinfestación de las viviendas. La comprensión de las relaciones de T. dimidiata con su hábitat, así como el empoderamiento de la comunidad, contribuyen al desarrollo de sistemas de control efectivos y perdurables. El propósito de esta revisión fue describir la distribución, los factores de riesgo, la ecología, las características entomológicas y los hábitats de las poblaciones de T. dimidiata en Colombia, y proponer alternativas de intervención acordes con las características particulares de esta especie. Triatoma dimidiata in Colombia: Distribution, ecology and epidemiological importanceTriatoma dimidiata is an important vector of Chagas disease in Central America and countries of northern South America. In Colombia, it has a wide geographical distribution with reported presence in 14 departments in the Andean, Caribbean, Eastern plains and Upper Magdalena regions, where it occupies different natural and artificial ecotopes. The species is considered a secondary vector in the transmission of Trypanosoma cruzi. Its presence in wild, peridomestic and intradomiciliary habitats in the Andean region, coupled with its ability to move between them, has allowed it to escape the control based on pyrethroids spraying, highlighting its importance in maintaining transmission of the parasite through the potential reinfestation of homes. Understanding the relation of T. dimidiata and its habitats, as well as the empowerment of communities, will contribute to the development of effective and lasting control systems. The purpose of this review was to describe the distribution, risk factors, ecology, entomological features and habitats of T. dimidiata populations in Colombia, and to propose alternative interventions in agreement with the specific characteristics of the species.

“…This species presents morphologically variable populations, but early attempts to delineate geographic boundaries between them failed, and clinal variation was proposed to explain this species' extensive polymorphism (reviewed by Dorn et al, 2007). Later on however, a combination of morphology, cytogenetics and molecular data led to the unambiguous detection of a cryptic taxon and the recognition of the Dimidiata species complex (Marcilla et al, 2001;Panzera et al, 2006;Dorn et al, 2007Dorn et al, , 2009). …”

Genetics and evolution of triatomines: from phylogeny to vector control

et al. 2011

View full text Add to dashboard Cite

Triatomines are hemipteran bugs acting as vectors of the protozoan parasite Trypanosoma cruzi. This parasite causes Chagas disease, one of the major parasitic diseases in the Americas. Studies of triatomine genetics and evolution have been particularly useful in the design of rational vector control strategies, and are reviewed here. The phylogeography of several triatomine species is now slowly emerging, and the struggle to reconcile the phenotypic, phylogenetic, ecological and epidemiological species concepts makes for a very dynamic field. Population genetic studies using different markers indicate a wide range of population structures, depending on the triatomine species, ranging from highly fragmented to mobile, interbreeding populations. Triatomines transmit T. cruzi in the context of complex interactions between the insect vectors, their bacterial symbionts and the parasites; however, an integrated view of the significance of these interactions in triatomine biology, evolution and in disease transmission is still lacking. The development of novel genetic markers, together with the ongoing sequencing of the Rhodnius prolixus genome and more integrative studies, will provide key tools to expanding our understanding of these important insect vectors and allow the design of improved vector control strategies.
