Necrophagous flies (Diptera: Sarcophagidae) of forensic importance in a plant system in eastern El Salvador

Abstract

Flies are among the first organisms to attend a corpse. Of these, the families Sarcophagidae and Calliphoridae have the greatest presence and use in post-mortem estimation. Our objective was to identify which are the most relevant organisms for post-mortem estimation in coffee farming systems.
Our work consisted in the collection of dipterans through two traps, a hanging trap for the capture of larvae and a ground trap for the capture of adult diptera, thus allowing us to know which dipterans are of forensic interest, since they colonize the baits and allow the estimation of larval cycles.
A total of 98 individuals were observed, divided into 3 species and one subfamily: Sarcophaginae (1).
Of the 3 species, only 2 colonized the baits and therefore the larval development time at 36°C was estimated: Sarcophaga crassipalpis 360 h, Sarcophaga rufficornis 384 h.
