Abstract

Rhodnius montenegrensis is a sylvatic triatomine and a vector of Trypanosoma cruzi, with records of its invasion into human dwellings. This study reports the first record of R. montenegrensis in Peru. Triatomines were collected from Attalea phalerata palm trees in peri-urban areas of the city of Iñapari, Peru. Seven specimens of R. montenegrensis were collected, and they were found to be infected with T. cruzi and/or T. rangeli. Additionally, some specimens showed human DNA in their gut contents. With this report, the number of triatomine species in Peru increased from 18 to 19, and the number of countries with the presence of R. montenegrensis rose from two to three (Brazil, Bolivia and Peru). The notification of R. montenegrensis, as well as the information related to the infection rate by T. cruzi and the presence of human blood as a food source for this insect vector, highlight the need for attention from the country's vector control programs to this new species recorded in Peru.

Rosa et al., 2012（半翅目，锥虫科）秘鲁：克氏锥虫（Chagas, 1909）（活动体目，锥虫科）在城市周边地区传播的预警

黑山锥虫是一种林木锥虫，是克氏锥虫的病媒，有入侵人类住所的记录。本研究报道了在秘鲁首次发现的黑山黑尾霉。从秘鲁Iñapari市城郊地区的Attalea phalerata棕榈树上采集了三聚螨。采集到7只黑山黑田鼠标本，发现它们感染克鲁兹和（或）朗格里弓形虫。此外，一些标本在它们的肠道内容物中发现了人类DNA。有了这份报告，秘鲁的三角蝽种类从18种增加到19种，存在黑山黑蝽的国家从2个增加到3个（巴西、玻利维亚和秘鲁）。黑山弓形虫的通报，以及与克氏弓形虫感染率和存在人类血液作为这种昆虫媒介的食物来源有关的信息，突出表明该国的媒介控制规划需要关注秘鲁记录的这一新物种。
