Performing quantitative sampling and determining faunistic analyses of dipterans is of fundamental importance in the analysis of ecological behavior, such as population dynamics and diversity, among other factors, for exotic and native species of necrophagous dipterans, so it is important to observe the type of bait used in traps to capture these dipteran species. This work aims to study structural parameters and faunistic indices of the diversity of Calliphoridae and Mesembrinellidae species as well as the abundance and diversity of species attracted to liver in two stages of decomposition: fresh liver and liver at 48 h of putrefaction. A total of 2826 dipterans were collected during the period from May 2021 to February 2022. We observed that liver in decomposition for 48 h was more attractive in the forest and rural environments, while fresh liver showed greater attractiveness in the urban environment; however, no statistical difference was evidenced between the attractiveness in the different environments. The Mesembrinellidae family and the species (Wiedemann, 1819) were collected mostly from deteriorated liver, while (Fabricius, 1775) showed no preference for any liver decomposition stage. The Wilcoxon test indicated that there is a significant difference between the preferences for putrefied bait in Mesembrinellidae, while in Calliphoridae, there was no preference for type of bait. The faunistic analysis showed that richness in the forest area was always higher when compared to the urban and rural areas. (Guimarães, 1977) and (Aldrich, 1922) were abundant and exclusive in the preserved environment, showing themselves to be good environmental bioindicators.
对双翅目昆虫进行定量采样并确定其动物区系分析，对于分析诸如种群动态和多样性等生态行为至关重要，这涉及到其他因素，包括外来和本地食尸性双翅目物种。因此，观察诱捕器中用于捕获这些双翅目物种的诱饵类型很重要。这项工作旨在研究丽蝇科和膜翅蝇科物种多样性的结构参数和动物区系指数，以及在肝脏分解的两个阶段（新鲜肝脏和腐烂48小时的肝脏）吸引到肝脏的物种的丰度和多样性。在2021年5月至2022年2月期间共收集了2826只双翅目昆虫。我们观察到，在森林和农村环境中，分解48小时的肝脏更具吸引力，而新鲜肝脏在城市环境中表现出更大的吸引力；然而，不同环境中的吸引力之间没有统计学差异。膜翅蝇科及其物种（维德曼，1819年）大多从变质肝脏中收集，而（法布尔，1775年）对任何肝脏分解阶段均无偏好。威尔科克森检验表明，膜翅蝇科对腐烂诱饵的偏好存在显著差异，而在丽蝇科中，对诱饵类型没有偏好。动物区系分析表明，与城市和农村地区相比，森林地区的丰富度始终更高。（吉马良斯，1977年）和（奥尔德里奇，1922年）在保存环境中数量丰富且独具特色，表明它们是良好的环境生物指标。
