A single box of infested avocados (mixed with
non-infested ‘fillers’) was removed from the cold
treatment on the 6th, 7th, 8th or 9th day and
placed in a walk-in refrigerator set at 7.69
0.10°C. After the pulp temperature reached a
minimum 4.2°C, the fruit were returned to the
cold treatment walk-in and the 12–16 days exposure
time was continued for quarantine treatment.
