What is one key use of forensic entomology?

Forensic entomology primarily involves the study of insects and their developmental stages to help estimate the post-mortem interval, commonly referred to as the time since death. Insects such as blowflies are among the first organisms to arrive at a decomposing body, and their life cycles are well-documented. By examining the species of insects present and their developmental stages, forensic entomologists can establish a timeline of when the death occurred. This information is crucial in criminal investigations, as it can provide law enforcement with important insights regarding the circumstances surrounding a death.

The other options do not align with the primary focus of forensic entomology. Analyzing radioactive substances pertains to a different field, specifically nuclear forensics. Identifying victims through dental records falls under forensic odontology, which evaluates dental characteristics to establish identity. Verifying alibis through location tracking relates to digital forensics and the examination of electronic data, which is distinct from the biological assessment performed in entomology. Thus, the use of insect activity to estimate the time of death is the central utility of forensic entomology.
