INTRODUCTION
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).
METHODS
Capture of triatomines on babassus and microscopic search for trypanosomatids in their digestive tube were carried out.
RESULTS
Four hundred ninety-four (494) specimens were captured (Rhodnius prolixus and R.robustus), of which 35.6% of the triatomines were positive for trypanosomatids.
CONCLUSIONS
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.
简介
本研究分析了巴西朗多尼亚州两种不同环境（牧场和林地）中巴巴苏棕榈果内锥虫体的发生和对三种原虫的污染情况。
方法
对巴巴苏棕榈果上的三种原虫进行捕获，并对其消化道内的锥虫体进行显微镜检查。
结果
共捕获 494 只（Rhodnius prolixus 和 R.robustus），其中 35.6%的三种原虫对锥虫体呈阳性。
结论
高的自然感染指数加上三种原虫的丰富度，表明有必要建立一个流行病学监测系统来监测媒介传播，并深化对亚马逊地区此类媒介生态的研究。
