Light-Trap Catch of the Harmful Insects in Connection with the Ozone Content of the Air

The study deals the efficiency of light trapping of the European Corn Borer (Ostrinia nubilalis Hbn.) and the Common Cockchafer (Melolontha melolontha L.) in connection with the ozone content of the air. The collected data of which use was made the Hungarian national light trap network between the years 1997 and 2006. We calculated relative catch values from the number of caught insects. We assigned these to the ozone values, we averaged them, and we depicted the results together with the regression equation though. We established that the light trapping of this species most fruitful when the ozone content of the air is high. As opposed to this, the low ozone values reduce the successfulness of the catching on one moderated only. Our results will be exploitable in the plant protecting and environment conservation researches.
