FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK Volume 63 2002 pp. 33^1. Data to the scale insect and whitefly (Homoptera: Coccoidea, Aleyrodoidea) fauna of the Sas-hegy Nature Reserve Area (Budapest, Hungary) F. KOZÁR, Zs. KONCZNÉ BENEDICTY and F. SAMU Abstract: Fifty-four scale insect and three whitefly species are reported from the Sas-hegy Nature Reserve Area. Forty species are new for the area, while three scale insect species (Eumirococcus borchsenii, Lecanopsis subterranea, and Acanthococcus baldonensis), and one whitefly species (Asterobemisia paveli) are new for the Hungarian fauna. The paper presents data on localities (collecting places), host plants, instars and density. Key words: Homoptera, Coccoidea, Aleyrodoidea, Hungary, Budapest, host plants, species list INTRODUCTION In the present paper we continue our earlier efforts (Kozár 1981, 1991, 1999; Kozár & Drozdják 1988, 1990, 1993; Kozár & Walter 1985; Kozár & Konczné Benedicty 1998, 2001, Kozár et al. 1999) to explore the scale insect fauna of the Hungarian National Parks and nature reserves. In the present paper we give an account of the scale insect fauna of the - a small nature reserve enclosed by the city of Budapest. Sas-hegy is a small dolomite hill, part of chain of similar hills on the western part of Budapest. The hill rises 180 m above its surroundings, which is a residential area in its immediate vicinity, but more industrialised areas and major roads are also found nearby. The steep dolomite slopes are covered with the original vegetation of dolomite grassland, dominated by Festuca pallens and Carex humilis. The rare endemic grass species Sesleria sadleriana is represented by a small patch on the northern slope. Two adventive species, black pine (Pinus nigra) and lilac (Syringa vulgaris) have also established patches on the hill. A strict nature reserve area was established in 1958. Its 30 ha area encompasses the entire grassy hilltop and a forested lower buffer zone.
