The tour was undertaken to facilitate implementation of vapour heat treatment (VHT) for the quarantine disinfestation of tropical fruits in Queensland. The Japanese MAFF (Ministry of Agriculture, Fisheries and Forestry) has adopted VHT as its preferred quarantine disinfestation treatment against fruit flies in tropical fruits such as mangoes, papaw, melons and small cucurbits, capsicums, and egg fruit. Any treatment, chemical or physical could be submitted for their consideration but residue free physical treatments are most likely to prove acceptable and of these heat is most appropriate to tropical fruits. They are by no means inflexible, as evidenced by acceptance of hot water dip treatments for Mexican mangoes but acceptance procedures are rigid. Clearly any treatment schedule already accepted for other countries on closely related pests to ours would have a better chance of acceptance than a less well known method. MAFF researchers have been closely involved in the development of VHT to its present high standards of efficiency and efficacy and their JICA (Japanese International Cooperative Agency) foreign aid VHT teams are ex-MAFF or seconded.
