The scale insect fauna of Sas-hegy is not well covered in the literature. The group (Coccoidea) was not even mentioned in the monograph of József Papp (1977) about the fauna of the hill. Fourteen species were mentioned earlier in the literature (Kosztarab 1955, 1959; Kozár & Nagy 1998; Kozár, Ördögh & Kosztarab 1977). The nomenclature follows the publications of Kosztarab & Kozár (1978, 1988), and Kozár (1998). Two species of whitefly were published earlier from Sas-hegy by Kozár & Bink-Moenen (1988), and Kozár & Danzig (1978). MATERIALS AND METHODS The materials were found during individual collections from the host plants, from the handheld suction sampler (DVAC) samples (Samu & Sárospataki 1995) and pitfall trap, from the collection of F. Samu (Samu & Szinetár 2000; Bleicher et al. 1999). These collecting methods proved to be efficient to collect various scale insects (Kozár & Miller 2001 ). The insects were collected within the boundaries of the Sas-hegy Nature Reserve Area. DVAC and pitfall trap samples were taken at five standard places over years. 1. Locality: closed rock grassland (Festuceto pallenti-Brometum pannoniéi - referred to as "Caricetum"); 2. Locality: endemic grassland of Seslerietum sadlerianae (referred to as "Seslerietum"); 3. Locality: dry open rock grassland on steep southern slope (Seseli leucospermi-Festucetum pallentis, referred to as "Festucetum"); 4. Locality: mosaic grassland, shrubs around (mostly Festuceto pallenti-Brometum pannoniéi, referred to as "Brometum"); 5. Locality: large grassy area on a moderate eastern slope (Festuceto pallenti-Brometum pannoniéi, referred to as "Pulsatilletum"). In the mass samples taken at the standard localities the identity of the host plant could not be determined. Instead we give the botanical host plant community surveyed. The visual surveys and some DVAC samples, where the sampling place is not mentioned, were done in different places of the area. In that case where the collecting method is not mentioned, these data originated from visual survey. The density is marked as F, where we follow the method of Kozár (1981). The material is deposited in the collection of the Plant Protection Institute, Hungarian Academy of Sciences (Budapest, Hungary), as microscopic slides. The rest is preserved in alcohol or in dry conditions in the same institute. In the evaluation and description of the materials the method elaborated by Kozár (1981) was followed. Most of the data originate from the collections of the senior author. Species reported earlier in the literature are also listed again for the sake of completeness. RESULTS During the surveys we found 54 species, belonging to 8 families in the territory of the Sas-hegy Nature Reserve Area. From these 40 species are mentioned for the first time from this place, three species are new for the Hungarian fauna. The distribution of the species according to families is as follows: Ortheziidae 2, Margarodidae 1, Pseudococcidae 18, Eriococcidae 5, Coccidae 12, Asterolecanii-
