Which term describes the time when insects begin colonizing a body, including pre-colonization by myiasis?

• A. Time of Colonization (TOC)
• B. Minimum Post Mortem Interval (minPMI)
• C. Successional Ecology
• D. Postmortem Interval (PMI)

Answer: (A)

Time of colonization refers to the moment when insects first begin to inhabit a corpse, marking the start of insect activity on the remains. This includes the initial stages of colonization, such as flies laying eggs or first instars appearing, which can encompass myiasis events. This is the best term because it specifically identifies when colonization begins, providing a starting point to interpret insect development data for estimating how long decomposition has progressed. In contrast, the minimum postmortem interval is only the lower bound of the time since death based on the earliest evidence, not the exact onset of colonization. Successional ecology describes the sequence and timing of insect arrivals over decomposition, not the precise start of colonization itself. The postmortem interval covers the entire time since death, including periods before colonization and after, so it doesn’t pinpoint when insect activity begins.
