Uso de nuevas herramientas para el control de triatominos en diferentes situaciones entomológicas en el continente americano

Abstract

El mejoramiento de la vivienda rural o periurbana, asociado con educación sanitaria de la población humana que vive en áreas endémicas para la enfermedad de Chagas,

Entomological Indices, Feeding Sources, and Molecular Identification of Triatoma phyllosoma (Hemiptera: Reduviidae) One of the Main Vectors of Chagas Disease in the Istmo de Tehuantepec, Oaxaca, Mexico

“…The houses examined were selected randomly in each locality and the local authorities were informed of the purpose of the study. Collections were conducted using the man/hour method 24 in domestic (on walls, beds, and floors) and peridomestic (the surrounding areas of the houses that included henhouses, wood piles, and stone walls) areas. Insect searches were done manually using flashlights.…”

Geographic distribution of Triatoma dimidiata and transmission dynamics of Trypanosoma cruzi in the Yucatan peninsula of Mexico.

“…Indeed, colonization of houses by migrating insects (from the same or other species) from sylvatic/peri-domestic environments has been documented, as well as the reemergence of population from residual individuals. [12][13][14][15][16] In addition, entomologic surveillance following control programs showed that adults flying from potential sylvatic areas could also contribute significantly to transmission, even in the absence of colonization of houses. 15,[17][18][19][20][21] In fact, the relationships between triatomine sub-populations from different environments are not always clearly understood, even though this has considerable implications for parasite transmission.…”

Re-infestation of houses by Triatoma dimidiata after intra-domicile insecticide application in the Yucatán peninsula, Mexico

“…The interruption of natural transmission is thus underway in the Southern Cone countries (Argentina, Brazil, Bolivia, and Chile) (WHO 1997). However, recolonization of houses by migrating insects (from the same or other species) from sylvatic/peridomestic environments has been documented, as well as the reemergence of populations from surviving bugs (Forattini et al 1984, Gorla 1991, Schofield 1991, Scorza et al 1994, Gajate et al 1996, Oliveira-Filho 1997, Dujardin et al 1999, Almeida et al 2000.…”
