摘要洞穴是一种独特的栖息地，居住着多样化和单一的生物群。在这些居民中，白蛉是新热带地区流行病学的重要对象，因为它们是利什曼原虫的媒介。这些昆虫的活动期通常是黄昏和夜间，但有报道称，洞穴中的白蛉有昼夜活动。因此，本研究的目的是评估在洞穴环境中的疼痛，米纳斯吉拉斯市白蛉的日常活动的周期性。在雨季和旱季，用灯光诱捕器连续操作5天收集白蛉。每12小时采集一次样品，并在暗相和暗相之间分离。共采集白蛉23种1,777只。最丰富的物种是Lutzomyia renei（Martins，Falcão和Silva）（44%），其次是Lutzomyia longipalpis（Lutz和Neiva）（15%），Evandromyia edwardsi（Mangabeira）（11%）和Micropygomyia quinquefer（Costa Lima）（6%）。的丰富性和丰度的总沙蝇和丰富的男性和女性沙蝇在无光区的洞穴没有不同的暗相和暗相之间，但不同的光周期在入口处和周围的洞穴。从我们对这些昆虫在该生态区的日常活动的研究中，将有可能知道一天中的哪个时段是访问或生活在这些环境中的脊椎动物（包括人类）暴露风险最大的时段。
Abstract Caves are unique habitats that are inhabited by a diverse and singular biota. Among these inhabitants are sand flies, which are of great epidemiological interest in the Neotropical region because they are vectors of Leishmania. The period of activity of these insects is usually crepuscular and nocturnal, but there are reports of diurnal activity of sand flies in caves. Thus, the aim of this study was to evaluate the periodicity of daily activity of sand flies in cave environments in the municipality of Pains, Minas Gerais. Sand flies were collected with light traps, which were operated for 5 consecutive days in the rainy season and in the dry season. Samples were collected every 12 h and separated between photophase and scotophase periods. In total, 1,777 sand flies of 23 species were collected. The most abundant species was Lutzomyia renei (Martins, Falcão, and Silva) (44%), followed by Lutzomyia longipalpis (Lutz and Neiva) (15%), Evandromyia edwardsi (Mangabeira) (11%), and Micropygomyia quinquefer (Costa Lima) (6%). The richness and abundance of total sand flies and the abundance of male and female sand flies in the aphotic zone of the caves did not differ between the photophase and scotophase, but differed between photoperiods at the entrance and at sites surrounding the caves. From our study of the daily activity of these insects in this ecotope, it will be possible to know which period of the day is of greatest risk of exposure of vertebrates who visit or live in these environments, including the human population.
