In the present paper two species of leafhoppers (Cicadomorpha, Cicadellidae) are reported for the first time from Hungary. Both species were collected from ornamental plants along highway margins in the vicinity of Budapest. Liguropia juniperi (Lethierry, 1876) has already been reported from several European countries. Opsius smaragdinus Emeljanov, 1964 has only been previously reported from Ukraine and Asian part of Turkey.
Survey of aphids on dicotyledonous herbaceous plants along the Hungarian highways on 33 sampling points revealed the presence of aphid infestation on Artemisia vulgaris L. in 4 locations. Macrosiphoniella artemisiae (Boyer de Fonscolombe, 1841) colonies were present on the youngest parts of the shoots each place. On one of the locations the gall forming Cryptosiphum artemisiae Buckton, 1789 was present. Gall containing shoots of the mugwort were collected to rear aphid nymphs to adult. On these shoots the overlooked Brachycaudus cardui Linnaeus, 1758 individuals developed into apterae. Artemisia absinthium L. was present on one location. This plant accommodated Macrosiphoniella absinthii (Linnaeus, 1758).
Measurements of radon in potable mineral waters along the Cota Mil Highway at two sites, La Castellana with five sampling points within 20 meters of each other and two collection points at the San Jose site were carried out from November, 1997 to December, 1998. Temporal radon variation patterns will be presented for the seven sampling points, which had very different water flow rates and short-term variations. The extraction of the radon from mineral waters was accomplished in the laboratory a few hours after sampling and the measurements were performed employing a radiation monitor with a scintillation cell 18 hours latter to insure that the radon and its decay products were in equilibrium. The results suggest that the increase of radon from the middle of February to the middle of November can be related to the decrease in atmospheric temperature and rainfall. The large differences in the minimum and maximum values of radon and the short-term variations show the need for many measurements over a year to quantify a correct annual value to be employed in dose calculation for radiological impact studies on human health. Finally, we have also concluded that water sampling points with very low water flow rates are more suitable for investigating the possible relation between radon anomalies and seismic events.
