Triatoma brasiliensis Neiva, 1911 is now considered the most important Chagas disease vector in the semiarid areas of northeastern Brazil. T. brasiliensis occurs in 12 Brazilian states, including Maranhão, Piauí, Ceará, Rio Grande do Norte, and Paraíba. T. brasiliensis is native to this part of Brazil, and thus persists in the natural environment. This species of Kissing Bug has the greatest potential to spread Chaga's 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. T. brasiliensis also has the greatest potential to colonize new areas and spread throughout northeastern parts of Brazil. This makes control problematic.

Trinervitermes trinervoides is a species of termite belonging to family Termitidae. It is native to and widespread in southern Africa where it inhabits mesic to semi-arid grasslands. Due to the snout on the head of soldiers, and their grass collecting habits, they are known as snouted harvester termites.
