Environmental and Dispersal-Related Drivers of Color Morph Distribution in Triatoma infestans (Klug, 1834) (Hemiptera, Reduviidae) Open
Understanding the dispersal capacity of Triatoma infestans, the main vector of Chagas disease in South America, is vital for vector control and managing recolonization after insecticide use. This study compares the seasonal frequency of me…

Where you live shapes who you are: morphological changes in urban Triatoma infestans Open
Introduction Urbanization has transformed landscapes, driving ecological and morphological changes in insects. Chagas, traditionally a multidimensional rural problem, is increasingly reported in urban areas. Triatoma infestans , the primar…

Bug off or bug out: mapping flight secrets of Triatoma garciabesi (Hemiptera: Reduviidae) through climate, geography, and greenery Open
Introduction Triatoma garciabesi is a vector of Trypanosoma cruzi , the causative agent of Chagas disease, and is found across northwest and central Argentina, southern Bolivia, and western Paraguay. It frequently invades rural houses duri…

Reconstructing Sordida subcomplex (Hemiptera, Reduviidae, Triatominae) phylogeny across species distribution range Open
BACKGROUND The conformation of the Sordida subcomplex has been a topic of prolonged debate, with diverse methodological approaches employed to discern its constituent species. Up to now, Triatoma sordida, T. garciabesi and T. rosai compris…

Relationship between genetic diversity and morpho-functional characteristics of flight-related traits in Triatoma garciabesi (Hemiptera: Reduviidae) Open
Background Triatoma garciabesi , a potential vector of the parasitic protozoan Trypanosoma cruzi , which is the causative agent of Chagas disease, is common in peridomestic and wild environments and found throughout northwestern and centra…

Relationship between flight muscle dimorphism and wing morphometry in Triatoma infestans (Klug, 1834) (Hemiptera, Reduviidae, Triatominae) Open
Triatoma infestans , the primary vector of Chagas disease in southern South America, is reported as a dimorphic species for flight muscle development and presents a marked phenotypic plasticity in traits related to flight. In triatomines, …

Urban vectors of Chagas disease in the American continent: A systematic review of epidemiological surveys Open
Background Chagas is a complex and multidimensional socio-environmental health phenomenon, in which different components converge and interact. Historically, this disease was associated with insect vectors found in the rural environment. H…

Parthenogenesis in weevils of the tribe Naupactini (Coleoptera, Curculionidae): a<i>Wolbachia</i>-density dependent trait? Open
The intracellular bacteria Wolbachia pipientis can manipulate host reproduction to enhance their vertical transmission. It has been reported an association between parthenogenesis and Wolbachia infection in weevils from the tribe Naupactin…

Characterization of melanic and non-melanic forms in domestic and peridomestic populations of Triatoma infestans (Hemiptera: Reduviidae) Open
Background Melanic (dark) morphs have been barely reported in peridomestic and sylvatic conditions for Triatoma infestans , the most important vector of Chagas disease in the Southern Cone of South America. Adults with dark and small yello…

A Microsatellite-Based Analysis of House Infestation With Triatoma Infestans (Hemiptera: Reduviidae) After Insecticide Spraying in the Argentine Chaco Open
Prevention of vector-borne transmission of Chagas disease mainly relies on residual insecticide spraying. Despite significant success at a regional scale, house infestation with Triatoma infestans (Klug) (Hemiptera: Reduviidae) still persi…

Morphometric variability among the species of the Sordida subcomplex (Hemiptera: Reduviidae: Triatominae): evidence for differentiation across the distribution range of Triatoma sordida Open
Wing shape best delimited the four species phenotypically. The proposed cryptic species, T. sordida from Argentina, differed from T. sordida from Brazil and Bolivia in all measured shape traits, suggesting that the putative new species may…

Where do these bugs come from? Phenotypic structure of Triatoma infestans populations after control interventions in the Argentine Chaco Open
House re-invasion by native triatomines after insecticide-based control campaigns represents a major threat for Chagas disease vector control. We conducted a longitudinal intervention study in a rural section (Area III, 407 houses) of Pamp…
