Abstract

Background and objectives: Triatomines are invertebrate hosts of Trypanosoma cruzi, etiological agent of Chagas Disease, a parasitosis that affects mammals, including humans. Considering these insects as natural sources of infection, this study aimed to evaluate the occurrence of triatomine infestation in home environment in the Municipality of Aurora, CE between 2012 and 2015. Methods: The secondary data on catches of species and analysis of T. cruzi infection were obtained from the Chagas Disease Control Program’s of Medical Entomology Laboratory Médica Zolide Mota Ribeiro in Juazeiro do Norte-CE. Results: A total of 1.176 triatomine specimens were captured, most of them found in the peridomiciliary area (85,71%), and were identified as Triatoma pseudomaculata (81,38%), T. brasiliensis (15,73%), Rhodnius nasutus (1,45%), Panstrongylus lutzi (1,28%), and Panstrongylus megistus (0,17%). Of the analyzed triatomines the majority were nymphs (64,80%), followed by adult males (17,52%) e 0,34% of them were infected by Trypanosoma cruzi. These infected insects belonged to the species Triatoma pseudomaculata (0,42%) and T. brasiliensis (0,54%), most of them in nymph stage (80%). Conclusion: The triatominal infestation index is significant in intradomicile and, especially, in the peridomicile, representing a health risk for the population of Aurora, CE, since triatomines parasitized by Trypansoma cruzi have already been diagnosed. Furthermore, the most prevalent species founded in this study are among the main vectors of Chagas disease in Cariri region, State of Ceará and Brazil.
