Abstract: Results of investigations in Somogy county on the insect fauna on common oak in 2005-2006 are presented. Three fields of collection were visited in 2 weeks periods. 13 new herbivorous species were found, potentially feeding on common oak. Amongst these rare species were found, especially in the family of Tenebrionidae. Keywords: Coleoptera, Heteroptera, Homoptera, Quercus Introduction The common oak used to be the most widespread oak In Hungary, in recent times its area has been decreasing. It amounts 9.2% (148.000 acres) of the forests in the country (FM ERSZ 1994). Most of the Hungarian data on the insect fauna of oak species is concerned with insects on oak with forestric importance (SZONTAGH 1962, 1973, 1985), group of species causing serious damage on oak. Few work has been done in Hungary (CSÓKA 1994) concerning the herbivorous fauna and interaction of the species. The general opinion is, that oak, especially Q. robur compensates loss with secondary growth. However, some author provided data on insect's flower prédation (SCUTAREANU-ROQUES 1993) or fecundity decreasing activity oîCurculio species (MAKSIMOVIC 1982, WORELLNIXON 1991). Several work has been done proving herbivors' impact on growth and physiology (KULMAN 1971, HILTON et al 1987). Therefore, it is important to investigate the whole insect fauna of the oak, and to uncover their interaction with their host plants. Methods and material Collecting of the oak fauna was carried out between 2005 and 2006, with different methods. The main methods used were collecting with an insect net (IN) in every second week, mainly on sunny days, in the afternoon (the net has 80 cm diameter, a 290 cm
