克氏锥虫恰加斯传播的生态流行病学情景部分由吻虫媒介生态学形成。“皇家棕榈”Attalea butyracea Kunth的存在是恰加斯病在帕纳马传播的一个主要危险因素，因为它们经常受到Rhodnius pallescens Barber的侵扰，Rhodnius pallescens Barber是一种主要的新热带锥虫。cruzi向量人们认为，在帕纳马，这种关系非常密切和独特，限制了R的利基市场。pallescens的，Att.丁酸。然而，在这里，我们提出的意见，T。克氏感染R.在帕纳马洛斯桑托斯省佩达西区，一种寄生在椰子树上的灰色植物Acrocomia aculeata Jacquin。在2015年5月至2016年8月期间，我们在旱季和雨季期间使用放置在每个棕榈冠上的老鼠诱饵陷阱从83个coyol棕榈中采样了接吻虫。我们收集了62个R。pallescens和Eratyrus cuspidatus Stål接吻虫。使用逻辑回归，我们发现，接吻虫在coyol棕榈侵扰的概率增加，在雨季，与果序数和棕榈高度。我们研究了成年R。pallescens bugs（n = 30），发现T. 67%的样本中存在Cruzi。我们能够分离并鉴定T. cruzi从寄生虫存在于粪便中的R. pallescens，所有寄生虫都属于TC I谱系。结果表明，绿色叶片数和房屋距离增加了T.这些结果突出了coyol棕榈树作为一个潜在的风险因素，在帕纳马的干燥拱门南美锥虫病传播。
Abstract Ecoepidemiological scenarios for Trypanosoma cruzi Chagas transmission are partially shaped by kissing bug vector ecology. The presence of Attalea butyracea Kunth, the ‘royal palm’, is a major risk factor for Chagas disease transmission in Panamá given their frequent infestations by Rhodnius pallescens Barber, a major neotropical T. cruzi vector. It was assumed that in Panamá this relationship was very close and unique, limiting the niche of R. pallescens to that of Att. butyracea. However, here we present observations about T. cruzi-infected R. pallescens infesting coyol palms, Acrocomia aculeata Jacquin, in Pedasí district, Los Santos Province, Panamá. Between May 2015 and August 2016, we sampled kissing bugs from 83 coyol palms using mice-baited traps placed at the crown of each palm during the dry and wet season. We collected 62 R. pallescens and one Eratyrus cuspidatus Stål kissing bugs. Using logistic regression, we found that the probability of kissing bug infestation in coyol palms increased during the rainy season, with infructescence number and palm height. We examined adult R. pallescens bugs (n = 30) and found T. cruzi in 67% of the samples. We were able to isolate and characterize T. cruzi from parasites present in the feces from R. pallescens, all parasites belonging to the TC I lineage. We found that green fronds number and house proximity increased T. cruzi infection probability in kissing bugs collected in coyol palms.These results highlight coyol palms as a potential risk factor for Chagas disease transmission in the dry arch of Panamá.
