Duponchelia fovealis Zeller was found in San Diego County, Calif., in a pheromone trap on July 1. This moth is native to southern Europe and North Africa, and feeds on a wide range of commercially-grown host plants, including azalea, begonia, cyclamen, geranium, gerbera, poinsettia, rose, pepper, pomegranate and corn. Larval feeding results in reduction in yield and quality of host plants.

 

The larvae can cause considerable damage by feeding on leaves, crowns and stems, and also by boring into the stems of some plants. In vegetables such as peppers, they can also bore into the fruit. In some crops such as roses however, a large population can survive on plant debris without causing significant crop damage.

Delimiting surveys have been initiated to define the current distribution of this pest in the United States.
