Abstract

The study focuses on the use of entomotoxicology to detect and quantify malathion, an organophosphorus pesticide, in Chrysomya megacephala larvae feeding on malathion-exposed decomposing cow lung. Malathion, often used in agriculture and medicine, can affect insect life cycles, potentially leading to inaccuracies in estimating the minimum post-mortem interval (mPMI) in forensic cases. The study optimized the extraction method of malathion from maggots and used Gas Chromatography-Mass Spectroscopy (GC-MS) for detection. Despite successful chromatographic separation of malathion, the pesticide could not be detected in the larvae, suggesting the need for further research using more realistic models. The findings highlight challenges in forensic entomotoxicology and underscore the need for further research with adequate sample sizes and real-world crime scene models.
