Immature phlebotomine sand flies develop in soils with essential and ideal characteristics for their life cycle, such as organic matter, humidity, temperature and low levels of light. Information regarding the potential breeding places of these dipterans is fundamental to understand the epidemiology and ecology of leishmaniasis, in addition to its importance to control them. In the present study, we aimed to find natural breeding sites of sand flies on Marambaia Island with the aid of emergence traps and direct search of immature forms using the flotation technique with saturated sugar solution in organic substrates of the region. Both methods were effective, with a total of 42 specimens of six different species - including some species that participate in the transmission cycle of American Tegumentary Leishmaniasis - collected by the emergence traps, and five immature forms obtained by floatation technique. However, further studies are still necessary, mainly with respect to the ecology and biology of immature sandfly stages, so that control measures focused on breeding sites can produce positive sustainable results in natural environments.
未成熟的白蛉在具有对其生命周期至关重要且理想特征的土壤中发育，例如有机物、湿度、温度和低光照水平。关于这些双翅目昆虫潜在繁殖地的信息，对于理解利什曼病的流行病学和生态学至关重要，此外对控制它们也很重要。在本研究中，我们旨在借助诱捕器以及通过在该地区有机基质中使用饱和糖溶液浮选技术直接搜索未成熟形态，来寻找马兰巴亚岛上白蛉的自然繁殖地。两种方法都很有效，通过诱捕器共收集到六种不同物种的42个标本，其中包括一些参与美洲皮肤利什曼病传播周期的物种，通过浮选技术获得了五个未成熟形态。然而，仍需要进一步研究，主要是关于未成熟白蛉阶段的生态学和生物学，以便针对繁殖地的控制措施能够在自然环境中产生积极的可持续成果。
