Background and Aims International quarantine rules prohibit exports of fruit from areas with fruit flies. Cold storage was tested from 1989 to 2012 as a postharvest treatment against the Mediterranean fruit fly (Medfly) in nine cultivars of Australian grown tablegrapes. The paper shows how market access was obtained. It reviews the methods, models and science that underpin fruit fly disinfestation. Methods and Results Tablegrapes were infested with immature stages of Medfly for large scale tests seeking 99.99% mortality at the upper 95% confidence level. Infested berries were exposed to 1, 2 and 3°C for 12, 13, 14, 15, 16, 18 and 20 days. No survivors were found in fruit held at 1°C for 16 days, 2°C for 18 days and 3°C for 20 days. Conclusion The data presented satisfy international requirements for access to quarantine‐restricted markets. Several decades of research are reviewed to show how science and phytosanitary regulation can be used to harmonise cold disinfestation treatments. Significance of Study This work has enabled Australia's tablegrape industry to gain access to several international markets. The science used and presented is expected to benefit disinfestation research.
