DOROW W H O (Senck Ges Naturforsch, Frankfurt, Germany), LANGE A (Bad Schwalbach, Germany), QUERBACH A (Univ Frankfurt, Germany), BRUGGEMANN W (Univ Frankfurt %26 Biodiv Climate Res Center, Frankfurt, Germany): Mediterranean Oaks (Quercus spp) and Central European Oak-feeding Lepidoptera in Southern Hesse, Germany. - Entomol Gener 34 (1-2): 119-130: Stuttgart 2012-09. - [Note] In three sites in Southern Hesse, which contain Quercus robur (Linnaeus 1753) as a dominant forest tree species. Mediterranean oak species [Q pubescens (Willdenow 1796), Q frainetto (Tenore 1813), Q ilex (Linnaeus 1753)] have been planted either as young trees (2 m high) or as saplings (2-3 years old). At the sites, the species composition of the Macrolepidoptera communities was assessed by diurnal collection, light and bait trapping, and a total of 79 obligatory or facultatively oak-feeding species were recorded. Larval stages were identified on the planted Mediterranean oaks at two sites. The Mediterranean oak species were readily accepted as host plants by 6 Central European Lepidoptera species already at very young stages after planting. Especially polyphageous species, which colonise new host trees by wind drifting on silk threads, like Lymantria dispar (Linnaeus 1758), Orgyia antiqua (Linnaeus 1758) or some Geometridae, were found. Larvae of the polyphageous gypsy moth. L dispar., were found on all oak species. In feeding experiments, 5th instar L dispar larvae exhibited very similar relative growth rates (RGR) on the deciduous species Q robur, Q frainetto and Q pubescens, with significantly lower values only on the evergreen Q ilex. In dual choice experiments between Q robur (i.e the native host species of the L dispar population in the research area) and the Mediterranean Quercus species, only Q ilex was significantly less accepted than the deciduous species.
