lation dynamics seems to be comparatively levelled out in the investigated period (Fig. 7). The frequency maps (Figs. 1-3) reveal that the majority of the population in Hungary inhabits the inundation areas along the Danube, that is, on the calciferous sand district between the Danube and the Tisza. Individual densities are rather low in most of the Transdanubia and in the NE regions beyond the Tisza. This latter datum is especially striking, 3ince the sandy soils of this area would afford favourable conditions for its proliferation, its absence from this region may be due to climatic factors,but also to the low pH values of the soil (,, acidic sand"). The data of captures are summarized In a Table. The upper part of the Table show the location of the light traps operating in areas of colder summers, the lower those in the warm s

er regions (average temperature totals of the active period of breeding below and above 3200 C°, respectively). Irodalom - References 1. DESEő, K. (I960): Tápláléklánc-vizsgálatok lucernásokban - Investigations on food-relationships in the fauna of lucernefields (Fol.Ent.Hung.
