and determined if the interruption of quarantine
cold treatment with a single temperature ‘spike’
affected survival or mortality of Mediterranean

8, HS+spike on day 9. All the treatments
were returned to cold treatment for the completion
of the exposure period (12–16 days) required
for the quarantine treatment temperature (1.1–
2.2°C).
