Final answer:
Forensic entomologists are the scientists who study the relationship between the succession of insect populations on a corpse and the Postmortem Interval (PMI), aiding in criminal investigations.
Step-by-step explanation:
The forensic entomologists are the scientists who relate the succession of insect population on a corpse to Postmortem Interval (PMI). Forensic entomology is a field of science that focuses on the study of insects and other arthropods in a legal context, primarily to determine the elapsed time since death. This discipline is a part of forensic science, where the knowledge of insects and their life cycles is applied to assist in the investigation of criminal matters, especially those involving death and decomposition of human bodies.
Forensic entomologists collect and analyze insect evidence from crime scenes to help provide insights into the timing and circumstances of a person's death, which can be essential in homicide investigations.
