Abstract :
Chrysomya megacephala (Fabricius) and Chrysomya rufifacies (Macquart) are two important species of blow flies that could be utilised as indicators to estimate the Post Mortem Interval (PMI) of corpses in forensic science. Determination of PMI of corpses is based on the larva size and its development stages. Development studies of eggs, larvae and pupae of Ch. megacephala and Ch. rufifacies at 27°C, 30°C and 33°C were carried out using an insect growth chamber. Data from these studies were used to construct growth curves and Accumulated Degree Hours (ADH) for both species. Ch. megacephala needs 9.15 days to complete one life cycle at 27°C, 8.54 days at 30°C and 6.76 days at 33°C. Development for Ch. rufifacies is slower than Ch. megacephala and takes 9.92 day at 27°C, 9.13 days at 30°C and 7.44 days at 33°C. Eggs of the two species hatch faster at 33°C compared to the two other temperatures. Low value of ADH shows shorter life cycle of that particular species. This study s findings are useful in estimating PML of the corpses found under various environmental temperatures.
