| 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 identification 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... |

| In order to determine the risk of transmission of Trypanosoma cruzi by triatomines in Metztitlan municipality, Hidalgo State, Mexico, entomological indexes were calculated and the characteristics of dwellings were described. A transversal, retrospective, descriptive, and observational study was performed by means of an intentional not probabilistic and expertise sampling from January to December of 2005 in 10 localities in which presence of triatomines were investigated either intra or peridomestic environmental in 699 houses. Building material and presence of infected triatomines with T. cruzi were registered to determine entomologic indexes. The triatomine species collected were: Triatoma barberi (Usinger) and T. mexicana (Herrich-Schaeffer) (Hemiptera:... |
