Abstract
Triatoma pseudomaculata Correˆa and Espõ´nola, 1964 and Triatoma juazeirensis Costa
and Felix, 2007 ( T. brasiliensis Neiva, 1911 [part]), are sylvatic vectors of Trypanosoma cruzi (Chagas,
1909), the causative agent of Chagas disease, in northeast BrazilÑespecially in the caatinga region.
In an area of caatinga in the State of Bahia, we compared the wild and peridomestic habitats of these
two species of Triatominae to assess their behavioral plasticity in relation to habitat selection in
different environments. In the sylvatic environment, the habitat of these two species is never shared.
T. pseudomaculata is found in trees and bird nests, but without apparent preference for any particular
tree species. In contrast, T. juazeirensis is exclusively rupicolous (found among rocks). Both species
invade peridomestic structures but do not display a signiÞcant ability to colonize human dwellings.
In the peridomestic area, they are highly adaptable to different habitats and can occupy substrates that
they do not colonize in the sylvatic environment. This behavioral plasticity seems to be more striking
in T. juazeirensisÑrupicolous in sylvatic environments but colonizing wooden structures in the
peridomicile in 80% of cases.
