Abstract

While testing the efficacy of herbicides on paddy weeds at the Rice Research Institute of Iran (RRII) in 2008, we encountered the failure of arrowhead (Sagittaria sagittifolia L., Alismataceae) seeds to germinate. Detailed investigation revealed physical damage of seeds caused by the larvae of Gynnidomorpha permixtana (Denis & Schiffermüller, 1775) (Tortricidae, Tortricinae, Cochylina). Further studies showed that larvae feed on the seeds and flowers of the host plant and destroy the achenes. Under laboratory conditions G. permixtana required 23–30 days to complete its life cycle. Arrowhead is a new host record for this moth species; furthermore, this is the first detailed record of a tortricid feeding on this plant.
