dc.description.abstractLeptodictya plana Heidemann is newly reported from Georgia, USA as a pest of ornamental grasses. Duration of development of Leptodictya plana, measured at six temperatures ranged from 23.3 days at 30°C to 40.5 days at 25°C. Development was not successful at 10, 15, 20, or 35°C, although eggs did hatch at 20°C. L. plana was present in the field from mid-March through late October. Highest population levels occurred in late August, which corresponded to the warmest temperatures of the season. Overwintering took place in the adult stage. Four generations occurred in central Georgia. Damage ratings on Pennisetum ornamental grasses averaged 20% for the 2008 and 2009 summer seasons. Thirty-two selections representing 24 species from varying genera of commercially available and five experimental Pennisetum purpureum ornamental grasses were evaluated for susceptibility to L. plana feeding and oviposition. While all sustained at least some feeding injury, only Pennisetum supported oviposition and development.
