Primeiro registro de Peckia (Squamatodes) trivittata (Curran) (Diptera: Sarcophagidae) colonizando cadáver humano carbonizado em área de restinga da Bahia, Brasil

Abstract

Resumo. Apresenta-se o registro de sarcofagídeos colonizando um cadáver carbonizado em uma área de restinga no município de Mata de São João, Bahia, o qual foi encontrado dentro de um recipiente metálico. As larvas coletadas da vítima foram criadas em dieta específica, com temperatura, umidade e fotoperíodo controlados até a fase adulta para possibilitar a identificação taxonômica. Sete espécimes de Peckia trivittata (Curran) emergiram da criação em laboratório. O presente artigo reporta o primeiro registro da espécie P. trivittata em cadáver humano e a primeira ocorrência dessa espécie para o estado da Bahia, Brasil.First record of Peckia (Squamatodes) trivittata (Curran) (Diptera: Sarcophagidae) colonizing carbonized human corpse in restinga area of Bahia, BrazilAbstract. It is presented a record of Sarcophagidae flies colonizing a human carbonized corpse in a restinga area in the municipality of Mata de São João, Bahia, which was found inside a metal container. The larvae collected from the victim were reared in a specific diet, with temperature, humidity and photoperiod controlled until the adult emergence to enable taxonomic identification. Seven adult specimens of Peckia trivittata (Curran) emerged from the laboratory creation. The present article also reports the first record of the species P. trivittata on the human corpse and the first occurrence of this species for Bahia State, Brazil.

First record of the Ravinia almeidai (Lopes, 1946) (Diptera: Sarcophagidae: Sarcophaginae) to the state of Bahia, Brazil

“…Unlike females of other dipterans, females of this family deposit first-instar larvae on the colonization substrate, and are therefore considered ovoviviparous insects. This characteristic may confer some kind of advantage to this group in terms of pioneering the colonization of the substrate, as already reported by Ramos et al (2018).…”

“…As mentioned above, some species of this family can develop in decaying organic matter, including vertebrate carcasses, which makes them an important tool widely used in forensic entomology, mainly for the determination of the post-mortem interval (PMI) (Denno & Cothran 1976;Byrd & Castner 2001;Barros et al 2008;Carvalho & Mello-Patiu 2008;Lopes et al 2018;Ramos et al 2018).…”

Rapid assessment of the knowledge about Coleoptera (Arthropoda: Insecta) of forensic importance in an urban fragment of the Atlantic Forest in Salvador, Bahia, Brazil

“…Forensic Entomology can be defined as the area of Biological Sciences that uses knowledge about insects and other Arthropoda in legal matters, with the medico-legal aspect as the main one, in which knowledge about the biology and taxonomy of insects is employed in criminal investigations, especially those related to violent deaths (Lord & Stevenson 1986;Ramos et al 2018). In this context, the presence of both immature and adult insects colonizing corpses is used as an essential tool for calculating the "Post-Mortem" interval (PMI) estimate (Pujol-Luz et al 2008;Ramos et al 2018).…”

“…Insects, which are pioneers in locating the body, use this new "micro-habitat" in various ways as copulation and/or reproduction sites, as well as a source of food and hiding (Catts & Goff 1992;Lopes et al 2018;Pamponet et al 2019). In this sense, animals that visit carcasses are valuable tools for different studies in forensic sciences (Oliveira-Costa 2007;Mise et al 2007;Ramos et al 2018;Lopes et al 2018;Pamponet et al 2019).…”

“…From the point of view, entomofaunistic inventories are highly relevant for the knowledge of insect fauna in a given area, in addition to serving as a basis for several other studies. Likewise, in Forensic Entomology, local studies are essential to be applied, since each environment has its particularities, such as temperature, humidity, soil type, so increasing the knowledge about the species that act in cadaverous decomposition in the different regions of Brazil and that can be used as tools in this aspect (Oliveira-Costa 2007;Ramos et al 2018).…”
