In forensic entomology, what does PMI stand for?

In forensic entomology, PMI stands for Post-Mortem Interval, which refers to the time that has elapsed since a person has died. Understanding PMI is crucial in forensic investigations as it helps forensic scientists and investigators establish timelines and better understand the circumstances surrounding a death. The presence and life cycle stages of insects found on or near a corpse can provide valuable information that aids in estimating PMI.

The other options do not accurately reflect the concept relevant to forensic entomology; for instance, Personal Medical Investigation and Pest Management Indicator are irrelevant to determining time of death, while Physical Mortality Index does not pertain to the methodologies used in forensic science. Therefore, Post-Mortem Interval is the correct terminology used in the context of forensic investigations involving insect activity.
