Study of Insect Larva Used to Detect Toxic Substance through Decomposed Bodies

Forensic entomology, Entomotoxicology is used to study the effect of toxins in the cadaver with the help of the insects. In some cases when toxicological samples are absent then the insects and other arthropods plays an important role to study the time since death and also the postmortem index (PMI). The identification and quantification of the present drug in the cadaver is studied through the analysis of the insects and other feeding arthropods present on the cadaver. The presence of different types of drug viz; benzodiazepines, nefopam, antidepressants, opiates, cocaine, heroin, barbiturates, alcohol etc. can also be identified through the study of insect larvae. Entomotoxicology is also used to establish the comparative study between the drugged and non-drugged bodies and the larvae samples collected, preserved in ethanol and used as controlled samples in laboratories.
