Impact of methamphetamine on the life cycle stages of two forensically important flies in Al-diwaneyah city

Introduction: In recent years, the entry of narcotic drugs, including Methamphetamine into Iraq by smugglers has increased the proportion of addict of this type of drugs (According to recent statistics of the Iraqi Ministry of Interior).

Materials and Method: The present study aimed to search the impact of Methamphetamine on life cycle stages of Chrysomya putoria and Chrysomya albiceps in estimating the postmortem interval (PMI). The first group fed on Methamphetamine -liver mixture and the second used as control group. The weight of larvae was measured after 24 to 54 hours of exposure. The time of both Pupariation and adult emergence was also accurately studied.

Results: The results confirmed that the larvae of C. putoria and C. albiceps exposed to Methamphetamine liver mixture developed faster than those in control, resulting in the conclusion that Methamphetamine impacted and motivates the growth of larva. There were no significant differences in the duration of pupariation between larvae exposed to Methamphetamine and control for both species. The adults of the two species took the same amount of time to emerge. The growth difference between both control and flies exposed to drug was observed clearly from 24 hours upwards. This provides very accurate and important information for researchers in the field of forensic sciences.
