The influence of food types, reproductive behaviour, and the existence of a possible stratification to the attractiveness of Calliphoridae and Mesembrinellidae flies may contribute to the definition of collection methodologies. Thus, we assessed the effectiveness of traps with two bait types exposed at two different heights in the forests for collecting the aforementioned families. Traps were exposed in the Amazon rainforest floodplain area, where 40 traps were installed in 20 trees, in three periods of the year. On each tree, one trap was installed at 0.6 m and the other at 10 m above the ground, with either bovine lung or fermented banana. A total of 1,173 individuals were collected, including 10 species of Calliphoridae (962 individuals) and four species of Mesembrinellidae (211 individuals). Of the total in each family, Calliphoridae was most abundant in 0.6m lung bait traps (41%) and Mesembrinellidae in the 0.6 m banana bait traps (29%). Calliphoridae showed greater species richness, abundance, and differentiation in composition in low traps with lung as bait. In conclusion, only dipteran species from Calliphoridae have been affected and responded the collection methodologies employed of we, which may highlight remarkable differences in collection and subsequent data interpretation of inventories and monitoring using these insects.
食物类型、繁殖行为以及可能存在的分层对丽蝇科和膜翅蝇科苍蝇吸引力的影响，可能有助于确定采集方法。因此，我们评估了在森林中两种不同高度暴露两种诱饵类型的诱捕器对采集上述科苍蝇的有效性。诱捕器设置在亚马逊雨林洪泛区，一年中的三个时期内在20棵树上安装了40个诱捕器。在每棵树上，一个诱捕器安装在离地面0.6米处，另一个安装在10米处，诱饵分别为牛肺或发酵香蕉。总共收集到1173只个体，包括10种丽蝇科（962只个体）和4种膜翅蝇科（211只个体）。在每个科的总数中，丽蝇科在0.6米高的牛肺诱饵诱捕器中数量最多（41%），膜翅蝇科在0.6米高的香蕉诱饵诱捕器中数量最多（29%）。丽蝇科在以肺为诱饵的低位诱捕器中表现出更高的物种丰富度、丰度和组成差异。总之，只有丽蝇科的双翅目物种受到了影响，并对我们采用的采集方法做出了反应，这可能凸显了在使用这些昆虫进行库存和监测的采集及后续数据解释方面的显著差异。
