Culture Survival Bias
Definition
A difference between the collected material and organisms represented among survivors. Only some collected insects may survive rearing and emerge as adults. Their species and condition need not represent everything in the original sample.
- Context
- Rearing interpretation
For example, one species may emerge successfully while another fails during rearing; the emerged adults alone would then misrepresent the original collection.
Keep suitable baseline material and collection records. Successful adult identification does not prove that all original larvae belonged to that species.
