Abstract INTRODUCTION The present study reports the presence of triatomines in natural, peridomestic, and intradomicile environments in Itacoatiara municipality, state of Amazonas, a non-endemic region for Chagas disease. METHODS Active search was performed inside tree trunks, and palm trees, residences, and peridomiciles localized near the forest area.

RESULTS:

Twenty adults and ten triatomines nymphs were collected, fifteen of which were from natural forests, thirteen from intradomiciles, and two from peridomicile areas.

CONCLUSIONS:

The new records of adults and nymphs of triatomines in the intra- and peridomiciles suggest the adoption of prophylactic measures for vector surveillance in the study area.
