The most common Gracillariidae, intercepted on Azalea is <em>Caloptilia azaleella<\/em>. This insect has been previously rated C by CDFA. A pest rating proposal is required to evaluate the current rating for this species.<\/p>\n<h5><strong>History &amp; Status:<\/strong><\/h5>\n<p><strong><u>Background<\/u><\/strong>:\u00a0 <em>Caloptilia azaleella<\/em> are small, yellow moths with purplish markings on the wings. Leaf mining stage is a yellowish caterpillar about half inch long. <em>Caloptilia azaleella<\/em> is known to attack only azaleas (<em>Rhododendron spp<\/em>.) worldwide. The larvae mine the leaf tissue; as these mines age, they cause brown blisters on the leaves. The mature larvae emerge from leaf tissue, then roll and tie the edge of the leaves around themselves for protection. They can cause considerable damage to greenhouse grown azaleas in North Carolina (Frank, 2016). Maximum infestation in Florida nurseries was noted from early spring through summer (Dekle, 2007). In Oregon, where it has been \u00a0introduced, there are three generations per year.<\/p>\n<p><strong><u>Worldwide Distribution<\/u><\/strong>:<\/p>\n<p><em>Caloptilia azaleella<\/em> is endemic to Japan but has been introduced to all azalea growing parts of the world including Europe (southern Britain), New Zealand and eastern Australia (T.E.R.R.A.I.N, 2018).<\/p>\n<p>In the North America, it has been found in the Unites States and Canada from Florida to Texas, Long Island, West Virginia and Ohio, California, Washington and British Colombia (Johnson and Lyon, 1994).<\/p>\n<p><strong><u>Official Control<\/u><\/strong>: <em>Caloptilia azaleella<\/em> has been listed as harmful organism in Chile (USDA -PCIT).<\/p>\n<p><strong><u>California Distribution<\/u><\/strong>:\u00a0 <em>Caloptilia azaleella<\/em> was introduced to California in 1962 for the first time (Essig Museum Online Database, 2010) and more recently observed in Sonoma county (2017) and Shasta county (2014) (iNaturalist, 2016).<\/p>\n<p><strong><u>California Interceptions<\/u><\/strong>:\u00a0 <em>Caloptilia azaleella<\/em> has been intercepted through high risk pest exclusion and interior quarantine programs in California (Pest and Damage Report Database, 2018).<\/p>\n<p>The risk <em>Caloptilia azaleella ( azalea leaf miner)<\/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> <em>Rhododendron<\/em> spp. grow best in filtered shade and prefer acidic soils with high organic content and excellent drainage (Pests in garden and Landscapes, 2017). This type of climate is found in northern California and extends down the coast to San Francisco Bay (American Rhododendron Society, 2018). Some of the maddenii-type rhododendron can grow in southern California as well. Since <em>C<\/em><em>. azaleella<\/em> is already introduced and present in Northern CA, its introduction and spread to the rest of the state is likely.

The life cycle is completed in one week. It overwinters as a last instar larva or pupa in a rolled leaf. Larva can be found on leaves all year around. There are three generations in western states and three to four generations in southern states. Because <em> azaleella<\/em> does not leave its host during the entire life cycle, it does not spread over large distances.
