                                                    Irradiation treatment for Ceratitis capitata
 

                                                                         (2011)


Scope of the treatment
This treatment applies to the irradiation of fruits and vegetables at 100 Gy minimum absorbed dose to prevent the emergence of adults of Ceratitis capitata at the stated efficacy. This treatment should be applied in accordance with the requirements outlined in ISPM 18:20031
Treatment description .
Name of treatment Irradiation treatment for Ceratitis capitata
Active ingredient N/A
Treatment type Irradiation
Target pest Ceratitis capitata (Diptera: Tephritidae) (Mediterranean fruit fly)
Target regulated articles All fruits and vegetables that are hosts of Ceratitis capitata
Treatment schedule
Minimum absorbed dose of 100 Gy to prevent the emergence of adults of Ceratitis capitata
Efficacy and confidence level of the treatment is ED99.9970 at the 95% confidence level.
Treatment should be applied in accordance with the requirements of ISPM 18:2003.
1 The scope of phytosanitary treatments does not include issues related to pesticide registration or other domestic requirements for approval of treatments. Treatments also do not provide information on specific effects on human health or food safety, which should be addressed using domestic procedures prior to approval of a treatment. In addition, potential effects of treatments on product quality are considered for some host commodities before their international adoption. However, evaluation of any effects of a treatment on the quality of commodities may require additional consideration. There is no obligation for a contracting party to approve, register or adopt the treatments for use in its territory.


This irradiation treatment should not be applied to fruits and vegetables stored in modified atmospheres.
Other relevant information
Since irradiation may not result in outright mortality, inspectors may encounter live but non-viable Ceratitis capitata (larvae and/or pupae) during the inspection process. This does not imply a failure of the treatment.
The Technical Panel on Phytosanitary Treatments based its evaluation of this treatment on the research work undertaken by Follett and Armstrong (2004) and Torres-Rivera and Hallman (2007), which determined the efficacy of irradiation as a treatment for this pest in Carica papaya and Mangifera indica.
Extrapolation of treatment efficacy to all fruits and vegetables was based on knowledge and experience that radiation dosimetry systems measure the actual radiation dose absorbed by the target pest independent of host commodity, and evidence from research studies on a variety of pests and commodities. These include studies on the following pests (with hosts in parentheses): Anastrepha ludens (Citrus paradisi and Mangifera indica), A. suspensa (Averrhoa carambola, Citrus paradisi and Mangifera indica), Bactrocera tryoni (Citrus sinensis, Lycopersicon lycopersicum, Malus domestica, Mangifera indica, Persea americana and Prunus avium), Cydia pomonella (Malus domestica; also artificial diet) and Grapholita molesta (Malus domestica; also artificial diet) (Bustos et al., 2004; Gould and von Windeguth, 1991; Hallman, 2004, Hallman and Martinez, 2001; Jessup et al., 1992; Mansour, 2003; von Windeguth, 1986; von Windeguth and Ismail, 1987). It is recognized, however, that treatment efficacy has not been tested for all potential fruit and vegetable hosts of the target pest. If evidence becomes available to show that the extrapolation of the treatment to cover all hosts of this pest is incorrect, then the treatment will be reviewed.
