Sixty three scale insect species are reported from the Mezőföld area (Hungary), a mosaic area of predominantly intensive agricultural land and scattered grassland and forested areas. In comparison, from the Kőrös-Maros National Park, dominated by natural grassland areas, only 31 species were reported. From the Mezőföld data 4 species were new for the Hungarian fauna and almost all species from Mezőföld were new for the given locality. The Mezőföld fauna could be characterised by more rare species and a lower Global Frequency Value (=higher level of species rarity), suggesting a higher overall conservation value. Scale insect species numbers show a strong negative correlation with the ratio of woody plantations. There was an overwhelming presence of a steppic scale insect species in grassland assemblages, and impoverished woody fauna of the studied wooded areas. However, there was no correlation with plant species number, with the area of natural vegetation, or with the area of loess steppe patches, which shows that the original loess step fauna is impoverished, heavily disturbed. In summary we can say, that the Mezőföld loess scale insect fauna is relatively poor, could be characterised by widely distributed, mezophilous, common species. However, it also has several important steppic elements, and therefore deserves protection.
