Behavior of Fannia sabroskyi (Seago, 1954) (Insecta, Diptera, Fanniidae), species of forensic importance, on different substrates for oviposition under laboratory conditions

Fanniidae is a family of Diptera (Arthropoda, Insecta) with worldwide distribution. They have very diversified eating habits. Some species are synanthropic and for carrying pathogens gain importance in the medical field. In addition, fanniids are also found in corpses in a more advanced stage of decomposition, so they can contribute to estimate the time of death in cases of violent death. In this study aimed to evaluate the selection behavior of females of Fannia sabroskyi (Seago, 1954) by the oviposition substrate and, from the obtained results, to classify their importance within the forensic context as potential or accidental. Three feeding substrates were offered to females during their reproductive period. The females had a greater preference for the liver for oviposition. Such results are important to better understand the biology of species of forensic importance.
