What does Time of Colonization (TOC) refer to?

• A. The time when flies lay eggs on a body, including pre-colonization by myiasis.
• B. The time when flies come to colonize a body, including pre-colonization by myiasis.
• C. The duration of fly activity after death.
• D. The time of discovery of the body.

Answer: (B)

Time of colonization is the moment insects first reach and begin to colonize a corpse, starting the insect-driven timeline used to estimate PMI. This focuses on when the first colonizing flies arrive and establish feeding on the body, which can involve early larval development that begins soon after arrival (sometimes described as pre-colonization by myiasis). It is not simply the moment eggs are laid, nor the overall duration of fly activity after death, nor the time the body is found. So the option that states the time when flies come to colonize a body, including pre-colonization by myiasis, best captures this concept.
