First report of colonization by Panstrongylus megistus (Burmeister, 1835) (Hemiptera, Reduviidae, Triatominae) in the Metropolitan Region of São Paulo, Brazil

Abstract We report the first known occurrence of Panstrongylus megistus (Burmeister, 1835) (Hemiptera, Reduviidae, Triatominae) in the Metropolitan Region of São Paulo, Brazil. In 2018, adult specimens were sent by residents to the competent authorities and, in the inspection of the property, a large focus associated with a marsupial nest was found. This finding reinforces the importance of the species in the state of São Paulo, serves as an alert for epidemiological surveillance and extends the species colonization area in the state of São Paulo.

摘要 本研究首次报道了巴西圣保罗大都会区出现大锥蝽（Panstrongylus megistus (Burmeister, 1835)，半翅目（Hemiptera）、猎蝽科（Reduviidae）、锥蝽亚科（Triatominae)）的记录。2018年，当地居民将采集到的成虫标本送交主管部门，经对该场所的勘查，发现一处与有袋类巢穴相关的大型虫源聚集点。该发现进一步凸显了该物种在圣保罗州的公共卫生重要性，为流行病学监测工作敲响警钟，并拓展了该物种在圣保罗州的定殖分布范围。
