“…These results could be due to an adaptive response to different climatic conditions, such as those recorded in the natural distribution area of T. mexicana in Mexico (López-Cárdenas et al 2005, Becerril-Flores et al 2007, Salazar-Schettino et al 2007, Villagrán et al 2008). According to most of the studied parameters in this study, T. mexicana cannot be considered to be an effective transmitter of T. cruzi to humans, which is different from other similar species, such as six species in the Phyllosoma complex (Martínez-Ibarra et al 2003a, Martínez-Ibarra & Novelo-López 2004.…”

“…In spite of the important role of T. mexicana in the transmission of T. cruzi to human populations in an epidemiologically important areas of Mexico, such as the states of Guanajuato, Hidalgo, Querétaro and San Luis Potosí (Becerril-Flores et al 2007, Salazar-Schettino et al 2007, Villagrán et al 2008, the biology and behavior of this species has not been documented.…”

“…This species usually occurs inside human houses (especially on walls and bedrooms) and in the peridomicile and is mostly collected from yards and in sylvatic foci at the center of Mexico (López-Cárdenas et al 2005, Becerril-Flores et al 2007, Salazar-Schettino et al 2007, Villagrán et al 2008. The climate in this area is mild and dry with 400-1000 mm annual rainfall and temperatures ranging from 0-40 o C (SEGOB 2005).…”

“…Todo el material empleado en el presente estudio fue obtenido a partir de colonias de T. barberi mantenidas en el Laboratorio de Microbiología Molecular de Enfermedades Infecciosas del Instituto de Ciencias de la Salud de la Universidad Autónoma del Estado de Hidalgo. Estas colonias se constituyeron a partir de material colectado en la localidad de El Ahorcado como previamente se reportó (Becerril-Flores et al 2007). Las colonias se alimentaron una vez por semana sobre ratón y se mantuvieron a una temperatura de 28°C con humedad relativa del 66%.…”

“…Un ejemplo de lo anterior son los estudios que se han realizado en el estado de Hidalgo, en los cuales se han identifi cado cuatro especies de triatominos a partir de colectar exclusivamente organismos adultos, dentro de las cuales se encuentran T. dimidiata, T. mexicana, T. gerstaeckeri y T. barberi (Becerril-Flores 2008información personal, Vidal-Acosta et al 2000. Recientemente, en un estudio realizado por nuestro grupo de investigación se determinaron nuevas zonas endémicas de la enfermedad de Chagas en Hidalgo, identifi cando organismos adultos de T. barberi, T. mexicana y T. dimidiata infectadas con T. cruzi, presentándose los aislados más virulentos en T. barberi (Becerril-Flores et al 2007).…”

-Triatoma barberi Usinger is a widely recognized vector of the protozoa Trypanosoma cruzi. The determination of its presence in the rural houses is made by direct observation of adults, nymphs, exuviae or eggs. For this reason, egg structural characteristics could facilitate the differentiation and identifi cation of species that inhabit such environments. In here, the morphologic characteristics of eggs of T. barberi are described and analyzed with special attention to the anterior pole of the egg. The structural analysis of eggs by scanning electron microscopy (SEM) showed the presence of a wide and rough chorion edge, which contain aeropyles and micropyles. A deep spermatic canal between the endochorion and exochorion, and a trabecular network in the interior were also observed. The operculum showed cells with irregular growth and undefi ned polygonal shape. Externally, the operculum cells forms two rings of projections that surround a single extension located to the center. The cellular projections resemble respiratory horns, although the presence of aeropyles was not observed. The chorion structural characteristics can help to identify and separate close species in the Triatominae subfamily.
