This study investigated the sandfly fauna of two quartzite caves in the Espinhaço Mountain Range, located in the municipality of Diamantina, state Minas Gerais. From August 2010-July 2011, entomological sampling was performed in the caves of Salitre and Monte Cristo with two HP light traps exposed in the photic and aphotic zones of each cave. The sandfly fauna consisted of 17 species, among which Lutzomyia cipoensis was predominant (54.76%). The male/female ratio in the total captures was 1:2.5. The aphotic zone showed the highest frequency of specimens captured (65%). A greater density of sandflies occurred during the summer (January-February), coinciding with the period of higher temperatures, humidity and rainfall. The presence of Lutzomyia longipalpis, Lutzomyia whitmani and Lutzomyia pessoai, proven or suspected vectors of leishmaniasis, is of concern because the area is visited by many tourists.
本研究调查了米纳斯吉拉斯州迪亚曼蒂纳市埃斯皮尼亚山两座石英岩洞穴中的沙蝇区系。2010 年 8 月至 2011 年 7 月，在 Salitre 和 Monte Cristo 洞穴中使用两个 HP 光陷阱进行了昆虫学采样，每个洞穴的光照和无光区域各暴露一个光陷阱。沙蝇区系包括 17 种，其中以 Lutzomyia cipoensis 为主（占 54.76%）。总捕获物中的雌雄比例为 1:2.5。无光区的标本捕获频率最高（占 65%）。沙蝇密度在夏季（1 月至 2 月）最高，与高温、高湿度和降雨期相吻合。Lutzomyia longipalpis、Lutzomyia whitmani 和 Lutzomyia pessoai 的存在令人担忧，因为这些地区有许多游客光顾，它们被认为是利什曼病的潜在或实际传播媒介。
