Insect-Age Estimate
Definition
An assessment of age or developmental progress under stated biological and modelling assumptions. Assess the development and association actually supported by the submitted specimens and records. Earlier cohorts may be missing, and material can arrive after developing elsewhere.
- Context
- Infestation timing
For example, a larva may enter a product after developing elsewhere, so its complete age need not equal the age of that product’s infestation.
The result is not automatically the duration of product contamination, continuous fly access or neglect. Each proposed earlier event requires its own support.
