Triatoma brasiliensis is now considered the most important Chagas disease vector in the semiarid areas of northeastern Brazil.

[1] T. brasiliensis occurs in 12 Brazilian states, including Maranhão, Piauí, Ceará, Rio Grande do Norte, and Paraíba.

This species of Kissing Bug has the greatest potential to spread Chagas disease due to its distribution over large areas where numerous people reside.

Triatoma species are commonly called Kissing Bugs because they bite around the mouth where skin is thinner.

The control strategies against this vector are very complex due to its capacity to infest natural and artificial environments presenting high levels of population density.
