Hydrocarbons Profiling for Age Determination Using Forensic Important Phorid Flies

Abstract

Forensic entomology studies provide crucial tool in estimating the post-mortem interval (PMI) of deceased individuals, with insects playing significant role in this process. Spiniphora genitalis, a forensically important phorid fly species, has been identified as a potential candidate for PMI estimation due to its abundance and rapid colonization of cadaveric remains. Traditional methods for determining the age of phorid fly larvae, such as morphological analysis and size comparison, can be complicated and inaccurate. This study aims to analyse cuticular hydrocarbons (CHC) compounds present on the cuticle of S. genitalis larvae at different ages (Day 1, Day 3, Day 7). The findings of this research will contribute reliable method for age determination of S. genitalis larvae, ultimately improving PMI estimation in forensic entomology.
