History and comments
In 1989 the defoliating moth Aplocera plagiata (=Anaitis) was released in several counties. Greenhouse reared colonies at the ODA Salem facility supplied releases for several more counties. The moth was first recovered in Jefferson County in 1993. The moth is widespread in NE Oregon, in the Cascades south to Douglas County, and recently in the Willamette Valley. There may be several generations per year. It does not occur in large enough numbers to cause much damage to plants.
