About this mock
This assessment probes advanced concepts in forensic entomology, focusing on the thermal-summation framework used to estimate the postmortem interval (PMI), the larval-development diagrams that underpin age assignment, the successional approach when larval data alone cannot reach far enough back in time, the principal sources of error and uncertainty that constrain any entomological opinion, and the collection protocols that determine whether scene evidence reaches the laboratory in usable condition. Each question targets precision knowledge that directly affects the reliability of a PMI opinion submitted to court.
Designed for students, MSc and BSc learners, and practitioners of forensic entomology who are moving beyond foundational identification skills into the quantitative and interpretive core of the discipline. The questions address accumulated degree days (ADD), accumulated degree hours (ADH), base-temperature thresholds, isomegalen and isomorphen diagrams developed by Grassberger and Reiter, the maggot-mass heat effect, entomotoxicology interference, indicator-species succession, collection containers, killing agents, and the rearing-versus-killing split.
Topics covered:
- Thermal summation: ADD, ADH, and the base temperature
- Isomegalen and isomorphen diagram construction and use
- Successional PMI estimation: indicator species and community analysis
- Sources of error: maggot-mass heat, drugs, concealment, local ecology
- Scene collection: sampling locations, killing agents, rearing splits
- Preservation and packaging of entomological specimens
Allow 30 minutes.
