Forensic Entomology: Evidence Collection, Preservation and Entomotoxicology

This mock covers the practical workflows that forensic entomologists follow from autopsy table to laboratory report: how to collect insect evidence systematically from a body, how to kill and fix specimens so they remain identifiable for years, how to rear immature insects to the adult stage for definitive species identification, and how drugs and poisons in a victim's body pass into carrion insects and alter larval development timelines.

Designed for students and practitioners of forensic entomology at BSc and MSc level, this test builds the hands-on procedural knowledge that underpins postmortem interval calculation. It is relevant to candidates preparing for NFSU MSc, UGC-NET Paper II Forensic Science, and CHFI or GCFA exams where insect-evidence handling appears in the methodology unit. It also addresses the use of insects as alternate biological samples when conventional toxicology or DNA specimens are unavailable due to advanced decomposition.

Topics covered:

• Systematic collection of insect evidence during formal autopsy
• Body-bag and clothing inspection as mandatory collection steps
• Killing, fixation, and ethanol concentration for stored specimens
• Labelling materials and chain-of-custody requirements
• Rearing larvae to adult emergence for species identification
• Rearing container design: substrate, ventilation, and temperature
• Entomotoxicology: drug effects on blow fly larval development
• Insects as alternate samples for toxicology and victim DNA

This is a foundation-level test. Mastery of these procedures is essential before attempting postmortem interval calculation or successional analysis. Allow 30 minutes.
