In southeast Amazon, Lutzomyia (Nyssomyia) flaviscutellata is the incriminated vector of Leishmania (Leishmania) amazonensis, a causative agent of zoonotic cutaneous leishmaniasis (CL). The optimal methods for surveying Lu. flaviscutellata were investigated in the Bragança region, northeast Pará State, Brazil, selected for the presence of Le. amazonensis. The performances of modified Disney traps and CDC light traps were compared in four ecotopes within and around four village transects during the wet and dry seasons. The physiological age of female sand flies was estimated and natural infection by flagellates was evaluated by dissection. Disney traps were better for detecting the presence of Lu. flaviscutellata, while CDC traps performed well for detecting Lutzomyia (Nyssomyia) antunesi, suspected vector of Leishmania lindenbergi. The former was more abundant during the wet season, when female flies were naturally infected with Le. amazonensis. These findings identified the environments of local transmission. In order to improve surveys of Lu. flaviscutellata as part of integrated epidemiological surveillance of CL, our recommendations include focusing vector surveys with Disney traps on forest fragments where people work, during the seasonal peak of the vector. Further field studies are required to make model‐based predictions of seasonal variations in the vectorial capacity of vector populations.

在巴西帕拉州Bragança地区内的城市中，黄褐斑病菌（Lutzomyia flaviscutellata）和其他皮肤利什曼病媒介的昆虫学调查，并记录了亚马逊利什曼原虫。

在亚马逊河的东南部，黄褐藻（Nyssomyia）是黄喉利什曼原虫（Leishmania）amazonensis（一种人畜共患性皮肤利什曼病（CL）的病原体）的致病媒介。陆测量的最佳方法。在巴西帕拉州东北部的Bragança地区调查了flaviscutellata，以发现Le的存在。亚马孙。在湿季和旱季，在四个村庄样带内及附近的四个生态区中，对改进的迪斯尼陷阱和CDC轻型陷阱的性能进行了比较。估计雌性沙蝇的生理年龄，并通过解剖评估鞭毛虫的自然感染。迪士尼陷阱更适合发现Lu的存在。黄cut，而CDC捕集阱在检测Lutzomyia（Nyssomyia）antunesi（疑似利什曼原虫lindenbergi的媒介）方面表现良好。前者在雨季更为丰富，当时雌蝇自然感染了Le。亚马孙。这些发现确定了本地传播的环境。为了提高对鲁的调查。flaviscutellata作为CL的综合流行病学监测的一部分，我们的建议包括在媒介的季节性高峰期间，用迪士尼陷阱对媒介进行调查，以调查人们工作的森林碎片。需要进行进一步的现场研究，以基于模型预测媒介种群矢量能力的季节性变化。
