PUSKÁS JÁNOS - NOWINSZKY LÁSZLÓ: A Balaton-felvidéken működő normál és UV-fénycsapdák Macrolepidoptera anyagának összehasonlítása

Summary In 1963 the light-traps worked paralell with normal and UV (blacklight) lamps at Balaton-highlands in Csopak and Keszthely. A species-list was made from the all Macrolepidoptera data and the data of richest families of (Sphingidae, Notodontidae, Arctiidae, Noctuidae and Geometridae), and the number of caught individuals also were shown. Using these informations the proportion of species and individuals caught by normal and UV light-traps were determined for each observing stations. We made a comparison at both observing station between the specific combination of normal and UV lighttraps using the Sörensen-index, and after it we also made a comparison between the data of two UV and normal light-traps. The distribution of individuals (equitability) among the species was examined first using the Berger-Parker-index which related is independent from the single and fundamental distribution. The probability, that the second caught specimen will belong to other species than the first one, was calculated with the Simpson-Yule-index formula. According to our results - expect the species of Geometridae family - more species and mainly more individuals were caught by UV light-traps than normal ones. The similarity of species - in collecting data of Csopak and Keszthely - is higher in data caught by UV trap than in normal one. It is remarkable the Sörensen-index of Notodontidae family is the lowest at both observ-ing stations and both kinds of light-traps. After the examination of species number and individual number it can be declared the equitability is on the highest level in Noctuidae family. A kézirat lezárva: 1996. december A szerzők címe: DR.
