Abstract
This study analyzed the occurrence and the contamination of triatomines by trypanosomatids in Orbignya speciosa (babassu) specimens in the State of Rondônia, Brazil, in two different environments (pasture and woods). Capture of triatomines on babassus and microscopic search for trypanosomatids in their digestive tube were carried out. Four hundred ninety-four (494) specimens were captured (Rhodnius prolixus and R.robustus), of which 35.6% of the triatomines were positive for trypanosomatids. The high index of natural infection along with the abundance of triatomines points out to the necessity to create an epidemiological surveillance system to monitor vector-borne transmission and deepen the studies on the ecology of such vectors in the Amazon.
Highlights
This study analyzed the occurrence and the contamination of triatomines by trypanosomatids in Orbignya speciosa specimens in the State of Rondônia, Brazil, in two different environments
This study aimed to analyze the occurrence and the contamination of triatomines found in palm trees, such as Orbignya speciosa, by trypanosomatids in two different environments in the state of Rondônia, Brazil
The triatomines collected belong to the genus Rhodnius and are sorted into two species: Rhodnius robustus 459 (92.9%) and Rhodnius prolixus 35 (7.1%), with 390 (93.8%) R. robustus and 26 (6.2%) R. prolixus in the pasture area and 69 (88.5%) R. robustus and 9 (11.5%) R. prolixus in the primary forest, respectively

This study aimed to analyze the occurrence and the contamination of triatomines found in palm trees, such as Orbignya speciosa (babassu), by trypanosomatids in two different environments (primary forest and pasture) in the state of Rondônia, Brazil.
