The use of DNA in forensic entomology refers to the application of DNA analysis techniques in the field of entomology to investigate crime scenes, specifically involving insects. Forensic entomology is the multidisciplinary science that studies the role of insects, such as flies and beetles, in criminal investigations. It involves the examination of insect activity, development, and behavior to estimate the postmortem interval (PMI) and other crucial information that can aid in criminal investigations.
The utilization of DNA in forensic entomology involves the extraction, amplification, and analysis of genetic material from insects found at a crime scene or on a victim's body. This genetic information can provide valuable insights into several aspects of an investigation, including the identification of insect species, the source of the insects, their life cycle stages, and even potential human DNA present on the insects themselves, such as blood residues. DNA analysis can aid in establishing the species involved, determining whether the insects are of forensic interest, and linking them to a particular individual or group.
By combining DNA analysis with entomological studies, forensic entomologists can provide crucial information regarding the time of death, movement of a corpse, and potential associations with suspects or victims. This evidence can be instrumental in corroborating or refuting witness accounts, providing new leads, or even exonerating innocent individuals.
The use of DNA in forensic entomology has significantly enhanced the accuracy and reliability of entomological evidence in criminal investigations, contributing to more robust decision-making processes and justice outcomes.
