<p><b>Country of Origin</b>:  Japan

<p><b>Commodity: Fresh apple fruit (all varieties)              </b></p>
<p><b>Scientific name:  </b><i>Malus</i> <i>domestica</i> Borkh<b> 


Common name</b>: Apple</p>
<p><b>Background</b></p>
<p>Apples (<i>Malus domestica</i>) of the Fuji variety are currently admissible from Japan (USDA-APHIS, 2008b) into the United States under the provisions of 7 CFR 319.56-27.  This includes mandatory cold treatment followed by fumigation with methyl bromide as provided in 7 CFR 305, and then, inspection of treated fruit by an APHIS inspector during preclearance inspections prior to export. The Japanese Ministry of Agriculture, Forestry and Fisheries (MAFF) has requested that APHIS consider allowing all varieties of <i>Malus domestica</i> apples from Japan (Bessho, 2007) into the United States under the same conditions as those required for the Fuji variety apples. </p>
<p><b>History:
</b></p>
<p>A review of APHIS pest interception data covering the 14 years (1994-2008) of imports has revealed no interceptions of quarantine significant pests and diseases of concern on commercial shipments of Fuji apples from Japan (AQAS-PestID 2008). Thus the mandatory cold treatment followed by fumigation with methyl bromide and then inspection by an APHIS inspector during preclearance of the commodity have been effective measures to mitigate pest risk at origin. 
</p>
<p>APHIS site visits to export production areas in Japan have not revealed any concerns about the efficacy of the systems approach currently in place for allowing Fuji apples from Japan into the United States (USDA-APHIS, 2004; USDA-APHIS, 2006a; USDA-APHIS, 2006b; USDA-APHIS, 2008a). 
</p>
<p><b>Pests of Concern:</b></p>
<p>The 1994 decision sheet for Fuji apples from Japan (USDA-APHIS, 1994) listed the following seven pests of concern, three insects, two mites and two diseases.</p>
<p>Insects:      </p>
<p>· <i>Adoxophyes orana </i>Fischer von Röeslerstamm<i>,</i> (Lepidoptera: Tortricidae) summer fruit tortrix<i> </i></p>
<p>· <i>Carposina sasakii </i>Matsumura (<i>=Carposina niponensis </i>Walsingham)<i>,</i> (Lepidoptera: Carposinidae) peach fruit moth </p>
<p>· <i>Conogethes punctiferalis,</i> (Lepidoptera: Pyralidae) Yellow peach moth </p>
<p>        Mites:</p>
<p>· <i>Tetranychus kanzawai </i>Kishida<i>,</i> (Acari: Tetranychidae) Kanzawa spider mite,</p>
<p>· <i>Tetranychus viennensis </i>(Zacher), (Acari: Tetranychidae) Hawthorn spider mite </p>
<p>Diseases:
</p>
<p>· <i>Gymnosporangium yamadae</i> Miyabe ex G. Yamada, (Uredinales: Pucciniaceae) Japanese Apple Rust </p>
<p>· <i>Monilinia fructigena</i> Honey ex Whetzel<i>,</i> (Helotiales: Sclerotiniaceae) brown rot.</p>
<p><b>Per APHIS regulations 7 CFR 319.56-27, the following measures are currently required for importing Fuji variety apples from Japan.</b></p>
<p>1. <b>Cold treatment and fumigation.</b></p>
<p>All approved apples must be cold treated for a minimum of 40 days at a pulp temperature of 1.1( C (34( F.) or less.  Following the 40 days of cold storage the apple shipment will be held in an approved facility until all core temperatures are sufficient for T109a fumigation treatment. Apples are fumigated with methyl bromide in approved facilities, for 2 hours, using treatments T109a-1, or T109a-2, depending on whether plastic or cardboard cartons are used for packing (USDA-APHIS, 2008c).  </p>
<p>2. <b>Preclearance inspection by an APHIS and MAFF inspector.
</b></p>
<p>All apples imported into the United States must be accompanied with a phytosanitary certificate issued by MAFF. 
</p>
<p>3. All shipments are subject to further inspection at port of entry.
</p>
<p>Subjecting commodities as apples to cold treatment for a definite period of time reduces the temperature at the core of the fruit and subsequently causes mortality to any internal pests that may be present in the fruit. Fumigating the fruit after the cold treatment kills any remaining surface pests. This combination treatment T 109a is an APHIS approved Probit 9 level (high mortality) treatment for the targeted insect pests. The effectiveness of the treatment is further evidenced by the lack of pest interceptions for the past 14 years (AQAS-PestID 2008). Though apple varieties may vary in their color, texture and other morphological features, the pest complex associated with them remains essentially the same and therefore we believe that the treatment currently in use for Fuji apples will be effective for the target pests on all other varieties.</p>
<p>Additional Measures:
</p>
<p>In addition to the requirements listed in 7 CFR 319.56-27, other measures practiced by Japan as standard production practices include:</p>
<p>Registration of orchards<b>: </b>Apple orchards designated for export are to be registered, inspected and certified by MAFF.  All apples must be bagged during the growing season, and free of pests and/or symptoms of brown rot and /or rust diseases.</p>
<p>Safeguards: From April – November 30, consignments must be safeguarded after export inspections are completed against reinfestation from pests. </p>
<p>These measures are included in the preclearance workplan for export of Fuji apples from Japan to the United States (USDA-APHIS, 2000).
</p>
<p><b>Discussion:
</b></p>
<p>Registration and inspection of apple orchards by MAFF, and bagging of all apples (as part of standard production practices) further ensures that quarantine pests of concern will not follow the pathway (Kitigawa et al., 1992).  Bagging apples specifically excludes high risk pests like Lepidoptera larvae (Bessin and Hartman, 2007; Love, 2002).  Inspection of packed fruit at the packing house by MAFF and oversight inspection by APHIS during preclearance program activities reduce the probability that pests will follow the pathway of fresh apples.  Finally, a mandatory cold treatment followed by fumigation with methyl bromide as provided in 7 CFR 305, which has been determined to be efficacious against a large numbers of pests, provides further security against the pests of concern (APHIS, 2008c).  Cultural practices and integrated pest control practiced in Japan reduce apple pest populations to very low levels (Rieselman, 2009). Varietal differences to quarantine treatment are considered to be non-significant by APHIS (Krissoff et al., 1997). Consequently, APHIS PPQ considers the risk of introduction of insects and diseases through the pathway of all varieties of fresh apples to be very low under the systems approach conditions presently in place for Fuji apples.
</p>
<p><b>Conclusion
</b></p>
<p>The history of the Preclearance Program in Japan indicates that no quarantine pests on commercial cargo of Fuji apples have been intercepted/reported/identified at U.S. ports of entry from 1994 to present, and no pests of concern have been reported from the pre-clearance program in Japan. APHIS PPQ considers the pest list on other <i>Malus domestica</i> apple varieties would not be significantly different from that of Fuji variety apples and that the measures currently in place for Fuji apples are also adequate to manage risks associated with all <i>Malus domestica</i> apple varieties from Japan.  Mandatory cold treatment followed by fumigation with methyl bromide as provided in 7 CFR 305, which has been determined to be efficacious against a large numbers of pests, provides further security against the pests of concern regardless of the variety (APHIS, 2008c; Krissoff et al., 1997). Therefore we recommend allowing the entry of additional <i>Malus domestica</i> apple varieties from currently approved areas in Japan to the United States under the provisions of 7 CFR 319.56-27.</p>
