Abstract

Insects are still rarely used to determine the post-mortem interval (PMI). The flies during
the period of laying eggs and forming larvae can estimate the time of death. This study aims to determine
the species abundance, and time of appearance of fly larvae on white rat carcasses that were treated with
burning. The experiment was conducted on 12 female white rats of the wistar strain, aged two-three months,
healthy, and weighing 150-200 g. The research was experimental which consisted of 4 treatments with 3
repetitions of each treatment with variations in burning time, namely A (10 min), B (20 min), and C (30
min). Observations were made for five days until the carcass underwent complete decomposition. Larvae
were taken from each carcass using tweezers, then put into vials containing 70% alcohol. The larvae were
then identified morphologically in the laboratory. There were types of fly larvae found in the burnt treated
white rat carcasses, namely Sarcophaga argyrostoma and S. haemorrhoidalis, while the controls were
Chrysomya albiceps, C. megacephala, and C. bezziana. S. argyrostoma was found with the highest
abundance in the treatment (39.9 individuals), while C. albiceps was found in the control (346.2
individuals). The first fly larvae that appeared in the burning treatment were S. argyrostoma (31 h) and
those of the control C. megacephala (31 h). The variation of combustion has or does not affect the type,
abundance, and time of appearance of fly larvae on the carcass.
