Abstract: -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 struct… Show more

“…In a study on the egg exochorium, Evangelista-Martínez et al (2010) demonstrated that cells shape and spots in relation to their location in the cephalic, median, and caudal regions have taxonomic value and can be used to characterize eggs of different species within the Triatominae subfamily. In the present study, the relevance of these areas was also demonstrated and, although no interspecific differences in cell shape were observed, ornamentation and spots differed between the 2 species in the 3 regions as observed using OM.…”

“…However, when the small eggs were washed with a low‐concentration alkaline solution, we observed polygonal ornamentation dominated with hexagons. Evangelista‐Martínez et al (2010) studied ornamentation in T. barberi eggs from the state of Hidalgo using 0.1 M cacodylic acid washes and later processed samples for SEM.…”

“…Triatoma barberi was described in 1939 by Usinger and is an endemic species of Mexico, where it has been reported in Colima, Hidalgo, Jalisco, Mexico City, Michoacán, Morelos, Oaxaca, Puebla, Guerrero, Tlaxcala, Guanajuato, Querétaro and Veracruz (Galvão et al 2003, Ramsey et al 2015). It is considered to be the most important vector in Mexico due to the presence of domestic and peri‐domestic habitats, its ability to live until 2,400 m above sea level, and its especially extensive geographical distribution and high infection rate in this country (Guzmán‐Bracho 2011, Cruz‐Reyes and Pickering‐Lopez 2006, Salazar‐Schettino et al 2010, Evangelista‐Martínez et al 2010).…”
