Abstract

The study deals the efficiency of light trapping of the Common Cockchafer ( Melolontha melolontha L.) (Coleoptera: Melolonthidae) in connection with the ozone concentration of air. The data of the Hungarian forestry light trap network w ere used for the years 1997 through 2006. We calculated relative catch values of from the number of caught insects. We assigned these to the ozone values of the respective days. For the classified d ate pairs regression equations were calculated. We established that the light trapping is most effecti ve if the ozone concentration is high. As opposed t o this, low ozone concentration reduces the success o f the catch. Our results may be utilized in plant protection and forest protection prognoses
