Status:<\/strong><\/h5>\n<p><strong><u>Background<\/u>:<\/strong>\u00a0 <em>Enarmonia formosana<\/em> is a wood boring moth whose larvae feed on the bark and sapwood of practically all rosaceous trees, including <em>Prunus<\/em> (cherry, almond, apricot, nectarine, peach, and plum), <em>Cydonia<\/em> (quince), <em>Malus<\/em> (apple), <em>Pyrus<\/em> (pear), <em>Sorbus<\/em> (mountain ash), and <em>Pyracantha<\/em> (firethorne)<sup>1<\/sup>.\u00a0 There is one generation per year<sup>2<\/sup>.\u00a0 Adult moths fly and lay eggs from April to September<sup>2<\/sup>.\u00a0 Eggs are laid in cracks, crevices, wounds, crotches, and lenticels of trees<sup>2<\/sup>.\u00a0 Eggs hatch after a few weeks and larvae seek out openings in the bark through which they enter the tree<sup>2<\/sup>.\u00a0 Larvae burrow deep into the cambium where they feed until the following spring<sup>2<\/sup>.\u00a0 Feeding causes dieback and wilting of the tree canopy and the damage makes the tree susceptible to bacterial and fungal diseases, frost damage, and other insect pests<sup>2<\/sup>.\u00a0 This secondary damage can be fatal to the tree.\u00a0 Because the moths usually attack mature trees, the most likely pathway for spread of cherry bark tortrix into California is through firewood of the host species.<\/p>\n<p><strong><u>Worldwide Distribution<\/u>:<\/strong> <em>Enarmonia formosana<\/em> is native to the Palearctic region.\u00a0 It is widespread in Europe, temperate Asia, and North Africa<sup>1<\/sup>.\u00a0 The first North American detection was in Richmond, British Colombia in May, 1989<sup>1<\/sup>.\u00a0 From there, it has been spreading to the south.\u00a0 It was found just across the border in Whatcom county, Washington in 1991<sup>2<\/sup> and then in Oregon in 2000<sup>4<\/sup>.\u00a0 Although the moth is widespread in western Washington, it has not been found in eastern Washington, suggesting that the Cascades may be a barrier to natural spread of the moth.<\/p>\n<p><strong><u>Official Control<\/u>:<\/strong> Oregon has established a quarantine against <em>Enarmonia formosana<\/em> regulating the entire state of Washington, the entire province of British Colombia, Multnomah and Clackamas counties in Oregon, and any other state, province, or territory where an established population of the moth is detected and not eradicated.\u00a0 The quarantine covers all plants in the genera <em>Crataegus<\/em>, <em>Cydonia<\/em>, <em>Malus<\/em>, <em>Prunus<\/em>, <em>Pyracantha<\/em>, <em>Pyrus<\/em> and <em>Sorbus,\u00a0<\/em>and unseasoned firewood derived from trees of these host plant genera. \u00a0Uninfested nursery stock plants of these genera that are less than two inches in diameter are exempted from the quarantine<sup>3<\/sup>.<\/p>\n<p><strong><u>California Distribution<\/u>:\u00a0<\/strong> <em>Enarmonia formosana<\/em> has never been detected in California.\u00a0 Trapping for the moth is included in CDFA\u2019s stone fruit commodity-based survey and it has not been trapped, further supporting its absence from the State.<\/p>\n<p><strong><u>California Interceptions<\/u>:\u00a0<\/strong> <em>Enarmonia formosana<\/em> has never been intercepted in any regulatory situations in California.<\/p>\n<p>The risk cherry bark tortrix (<em>Enarmonia formosana<\/em>) would pose to California is evaluated below.<\/p>\n<h5><strong>Consequences of Introduction:\u00a0 <\/strong><\/h5>\n<p><strong>1) Climate\/Host Interaction:<\/strong> Rosaceous plants are widely cultivated in California and <em>Enarmonia formosana<\/em> is likely to establish wherever they are grown.
