Key to larvae of Castanea-feeding Olethreutinae frequently intercepted at U.S. ports-of-entry (Lepidoptera: Tortricidae).

J. W. Brown, F. Komai


At least six species of olethreutine moths are common pests of chestnut (Castanea spp.) outside of the United States. Three are native to, or naturalized in the Mediterranean Region of Europe: Pammene fasciana (L.), Cydia splendana (Hübner) and Cydia fagiglandana (Zeller). Three are native to the Far East: Eucoenogenes aestuosa (Meyrick), Cydia kurokoi (Amsel), and Cydia glandicolana (Danilevsky). Commercial chestnuts imported into the U.S. from these regions are fumigated routinely to prevent entrance of these and other pests. However, larvae of these species frequently are encountered by agricultural inspectors at ports of entry in personal baggage and other cargo. A key to the larvae of these six species is presented, along with summary descriptions and select references on their biology, detection, and control in association with chestnuts.
