Abstract Content

Necrophagous insects such as blow flies are naturally attracted to carrion. As the maggots feed on carrion, they indirectly serve as a biological clock which can be used by forensic entomologists to estimate the minimum post-mortem interval (mPMI), or post-colonization-interval. In Malaysia, at least 24 species of forensic importance dipterans have been reported from human corpses, with Chrysomya being the dominant genus followed by other genera of calliphorids, sarcophagids and muscids. Forensic entomological cases examined at the Faculty of Medicine, Universiti Teknologi MARA revealed a few uncommon dipteral species colonization on human corpses. One case reported Eristalinus arvorum (Diptera: Syrphidae), a species of rat-tail maggots within a human skull. Another case reported third instars of Piophila casei (Diptera: Piophilidae) collected from a human skeleton where numerous pupae of Chrysomya nigripes (Diptera: Calliphoridae) were attached on the skull and scapula. The unique biology and behaviours of these species provide clues to the case pertaining to mPMI, stages of decomposition, insect successional sequence, and ecoregion of the scene. However, gaps in knowledge and limitations from the cases should be addressed to improve future applications. Research opportunities in forensic entomology are also highlighted in this presentation.
