Interpretive Summary: Caterpillars of the moth family known as “leaf-rollers” inflict considerable damage on forest trees, ornamentals, and crops, causing millions of dollars in lost agricultural income annually. In this paper we report the first records of four leaf-rollers attacking cultivated blueberries in Argentina. This information will be useful for those involved in the production of blueberries, scientists interested in host breadth of plant-feeding moths, and action agencies such as APHIS PPQ, whose duties include the detection of foreign species at U.S. ports-of-entry.

Technical Abstract: Four species of tortricids were reared from cultivated blueberries, Vaccinium corymbosum L. (Ericaceae), from four field sites in the province of Buenos Aires, Argentina: Clarkeulia bourquini (Clarke, 1949), Clarkeulia deceptiva (Clarke, 1949), Argyrotaenia spheralopa (Meyrick, 1909), and Platynota meridionalis Brown, 2012. These are the first records of these polyphagous tortricids on Vaccinium. Larvae were discovered primarily on the flowers, buds, and fruit of the host plant, where they fed externally.
