Sand flies play a crucial role as vectors of bacteria, viruses, and protists, with Leishmania being the most notable among them, transmitted to vertebrate hosts during blood feeding. Understanding the feeding behaviours of sand flies is imperative for gaining insights into their eco-epidemiological roles in the transmission of these infectious agents. This systematic review aimed to answer the question 'What are the blood-feeding sources identified in Brazilian sand flies?' to provide an analysis of their blood-feeding habits. The diverse range of at least 16 vertebrate orders identified as blood sources for 54 sand fly species across different geographic regions was summarised, and the factors potentially associated with the risk of bias in the included studies were analysed. The findings broaden the discussion concerning methods used to identify blood meal sources and shed light on the implications of sand fly feeding behaviours for the transmission dynamics of Leishmania.
沙蝇在传播细菌、病毒和原生动物方面发挥着至关重要的作用，其中最引人注目的是利什曼原虫，它在吸血时传播给脊椎动物宿主。了解沙蝇的取食行为对于了解它们在这些传染病原体传播中的生态流行病学作用至关重要。本系统综述旨在回答“在巴西沙蝇中发现了哪些吸血源？”这个问题，以分析它们的吸血习惯。综述总结了至少 16 个不同的脊椎动物目，这些目被确定为来自不同地理区域的 54 种沙蝇的血液来源，并分析了与纳入研究中的偏倚风险相关的因素。这些发现拓宽了有关识别血液来源方法的讨论，并阐明了沙蝇取食行为对利什曼原虫传播动态的影响。
