Abstract

Chagas disease (CD) is a zoonosis that affects about 2 million people in Brazil and is transmitted by blood-sucking insects. Populations of these vectors domiciled in Brazil are now virtually eliminated. However, it is recognized that the eradication of the domestic environment of these populations can leave a vacant ecological niche that could be occupied strictly sylvatic or peridomestic insects. The species of Triatoma matogrossensis subcomplex, are found in central Brazil. Some are found in rocky areas and others were caught in a domestic environment. In an analysis of the recent literature notices the epidemiological importance of the species Triatoma matogrossensis subcomplex, tending to hosting and transmission capacity of T. cruzi. However, knowledge of species biology, ecology and phylogeny of the sub-complex is still rare. Thus, the objectives of this work are: (1) study the genetic and morphological variability of populations of species of "sub-complex" Triatoma matogrossensis, (2) characterize the populations of species of Triatoma matogrossensis sub-complex by wing geometry, (3) characterize the populations of Triatoma matogrossensis sub-complex species by head geometry (4) Characterize populations of species Triatoma matogrossensis subcomplex by comparing the sequences COI mitochondrial genes, 16S CytB, (5) Characterize populations of species Triatoma matogrossensis subcomplex by microsatellite analysis.
