Expert Consultation on phytosanitary treatments for The Bactrocera Dorsalis complex

The Standards Committee (SC) was informed about concerns from some countries on the absence of phytosanitary treatments for the control of Bactrocera invadens, Drew, Tsuruta & White (Diptera: Tephritidae). After discussion between the IPPC Secretariat and the National Plant Protection Organization (NPPO) of Japan it was agreed to organize an expert consultation meeting on phytosanitary treatments to control fruit flies of economic importance from the Bactrocera dorsalis complex in December 2014 in Okinawa. The Technical Panel on Phytosanitary Treatments (TPPT), the Technical Panel on Fruit Flies (TPFF) and the SC all agreed such a meeting would be of particular interest to those areas or countries affected by this pest. Thus, twenty-four researchers from twelve countries met in Okinawa, Japan, between 1 and 5 December 2014 for an expert consultation on phytosanitary treatments for fruit flies belonging to the Bactrocera dorsalis complex. The meeting was hosted by the Plant Quarantine Office of the Japanese Ministry of Agriculture, Forestry and Fisheries, and partly funded by Japan, the FAO/IAEA Joint Division of Nuclear Techniques in Agriculture and the IPPC Secretariat.

Setting the scene was a discussion of the implications of the recent taxonomic synonymization of four fruit fly pests in the Bactrocera genus on the application of phytosanitary measures particularly in sub-Saharan Africa where B. dorsalis outbreaks have been occurring in recent years.

Participants presented their countries’ research on phytosanitary treatments against the different fruit flies. Issues in the design, conduct, operationalization, evaluation and presentation of the data of post-harvest treatments were discussed. Participants collated a comprehensive list of NPPO-approved treatments for B. dorsalis complex species.
