Biological systems are extremely sensitive to changes in ultraviolet radiation reaching the Earth's surface. Atmospheric ozone absorbs considerable part of the UV radiation coming from the sun and harmful for biosphere so only a very small part of it can reach the Earth's surface; thus, organisms adapted to that intensity. The light-trap success of European corn borer (Ostrinia nubilalis Hbn.) was examined at those nights when during the previous day the UVB radiation had different intensity. UVB data used for examination come from measurements in the Keszthely observatory of the Hungarian Meteorological Service by Robertson-Berger UV-Biometers. The light-trap catch data of European corn borer originated from the national light-trap network between 1994-1998. Relative catch (RC) values were calculated from the daily data of UVB radiation relating to the summer half-year. The daily data were divided with the weighted average values of previous, actual and following ten days. We calculated RC values from daily light-trap results of European corn borer for all observing stations and swarming times. Our results prove light-trap catch is low if the values of UVB radiation are significantly lower considering the average.
