Abstract

Abstract.

is the most important vector of Chagas disease in the Caatinga eco-region of northeastern Brazil. Wild populations have been reported only from rocky outcrops. However, this species frequently infests/re-infests houses in rock-free sedimentary lowlands. We therefore hypothesized that it should also occupy other natural ecotopes. We show that a common Caatinga cactus, , locally known as xiquexique, often harbors breeding colonies apparently associated with rodents (n = 44 cacti, infestation rate = 47.7%, 157 bugs captured). Our findings suggest that infested cacti might be involved in house re-infestation by in the Caatinga region.
