                                                  Irradiation treatment for Cydia pomonella
 

                                                                        (2009)




Scope of the treatment
This treatment applies to the irradiation of fruits and vegetables at 200 Gy minimum absorbed dose to prevent the emergence of adults of Cydia pomonella 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 Cydia pomonella
Active ingredient: N/A
Treatment type: Irradiation
Target pest: Cydia pomonella (L.) (Lepidoptera: Tortricidae)
Target regulated articles: All fruits and vegetables that are hosts of Cydia pomonella.
Treatment schedule
Minimum absorbed dose of 200 Gy to prevent the emergence of adults of Cydia pomonella.
Efficacy and confidence level of the treatment is ED99.9978 at the 95% confidence level.
Treatment should be applied in accordance with the requirements of ISPM 18 (Guidelines for the use of irradiation as a phytosanitary measure).
This irradiation treatment should not be applied to fruit and vegetables stored in modified atmospheres.
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.

Other relevant information
Since irradiation may not result in outright mortality, inspectors may encounter live, but non-viable
Cydia pomonella (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 Mansour (2003) that determined the efficacy of irradiation as a treatment for this
pest in Malus domestica.
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 and hosts: 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 and artificial diet)
and Grapholita molesta (Malus domestica and artificial diet) (Bustos et al., 2004; Gould & von
Windeguth, 1991; Hallman, 2004, Hallman & Martinez, 2001; Jessup et al., 1992; Mansour, 2003;
von Windeguth, 1986; von Windeguth & 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.
