Sarchophagid flies (Insecta, Diptera) from pig carcasses in Minas Gerais, Brazil, with nine new records from the Cerrado, a threatened Neotropical biome

Abstract

ABSTRACT. Sarchophagid flies (Insecta, Diptera) from pig carcasses in Minas Gerais, Brazil, with nine new records from the Cerrado, a threatened Neotropical biome. The diversity of the Sarcophagidae fauna of the Cerrado biome, also know as the Brazilian Savanna, is still underestimated. In this research we collected flies in the state of Minas Gerais, Brazil, during a Forensic Entomology experiment. Samples were collected throughout the decomposition process of domestic pig (Sus scrofa Linnaeus) carcasses, and the experiments were conducted in areas of pasture and semideciduous forest. A total of 85,694 adult flesh flies belonging to 57 species were collected from all carcasses. New records for nine species of Sarcophaginae are provided, including the first record of Blaesoxipha (Acridiophaga) caridei (Brèthes, 1906) to Brazil, and new occurrences of the following species for the Cerrado and/or for the state of

Saprophytic flies in impacted areas of the Belo Monte Dam, Pará, Brazil (Diptera: Mesembrinellidae, Neriidae, Ropalomeridae, and Sarcophagidae): community composition, abundance, and species richness

“…Ravinia effrenata is a new occurrence for the state of Pará, since in Brazil it was recorded only for Roraima, Maranhão, Minas Gerais, and Pernambuco (Lopes & Leite 1990, Mello-Patiu et al 2014, Barbosa 2019. This was the second most abundant species in this study, and no specimens were reported by Esposito & Linhares (2002) or by Souza et al (2011).…”

“…However, in seven species were obtained, indicating that animal carcasses and decomposing fruit are attractive for this genus. Helicobia aurescens (Townsend, 1927) is a new record for the Brazilian Amazon, since in Brazil it was recorded for Distrito Federal, Mato Grosso do Sul, Minas Gerais, Paraná, Pernambuco, Rio de Janeiro, and São Paulo (Pape 1996, Barros et al 2008, Mello-Patiu et al 2014, Barbosa 2019, Toma et al 2020).…”

New records of Sarcophagidae (Insecta: Diptera) collected in Cerrado fragments in the municipality of Campo Grande, Mato Grosso do Sul state, Brazil

“…Previous distribution (PaPe 1996;barros et al 2008;rosa et al 2011;Souza et al 2015): Neotropical: Argentina, Brazil (Distrito Federal, Maranhão, Minas Gerais, Paraná, Rio de Janeiro, São Paulo). Helicobia aurescens has already been caught in traps baited with animal tissues (decomposing bovine liver and lung), dog feces, and domestic pig and rodent carcasses (Moura 2004;Mulieri et al 2008;barros et al 2008;Mulieri et al 2010;Mello-Patiu et al 2014;souza et al 2015). In Curitiba, Paraná state, this species showed a preference for inhabited areas (Ferreira 1979).…”

“…This species showed mostly coprophagous and scavenger habits (loPes 1973;D'alMeiDa 1983;Dias et al 1984b;D'alMeiDa & liMa 1994;MarChiori et al 2001;barros et al 2008), and was correlated to the rural area in Guajira, Colombia (valverDe-Castro et al 2017). was collected with traps containing powdered milk and agar, fish, rotten banana with brown sugar, human feces, and domestic pig carcass (loPes 1973;loPes 1975;Mello-Patiu et al 2014;valverDe-Castro et al 2017). This species was captured exclusively in a forest area in Colombia, being attracted to fish bait, however that study involved only two specimens (valverDe-Castro et al 2017).…”

“…Previous distribution (PaPe 1996;barros et al 2008;buenaventura & PaPe 2013;sousa et al 2015): Nearctic: Mexico (San Luis Potosí); Neotropical: Argentina, Bolivia, Brazil (Amazonas, Ceará, Distrito Federal, Maranhão, Mato Grosso, Rio de Janeiro, São Paulo), Costa Rica, Guyana, Nicaragua, Panama, Peru, Trinidad & Tobago. This species has already been collected with traps baited with fish, chicken viscera, bovine lung, human feces, and domestic pig carcass (YePez-Gaurisas et al 2013;Mello-Patiu et al 2014;sousa et al 2015); Peckia (E.) anguilla was considered asynanthropic in a study carried out in Belo Horizonte (Dias et al 1984a), but in Colombia, this species was more abundant in rural area than in urban and forest areas. In the last two areas it showed the same proportion of collected specimens and showed attraction to fish (YePez-Gaurisas et al 2013).…”
