Abstract

European corn borer (Ostrinia nubilalis Hbn.) is the most dangerous pest of maize (Zea mays L.) in Poland. Since 2009, the pest has been present in all provinces. This species requires monitoring to determine the need and timing of non-chemical or chemical control. One of the most effective methods of observing the appearance of the species in maize fields is the use of light traps that catch males and females of this species during the night. These are precision devices. In the tests carried out, it was checked which potential light sources would be useful to create a mobile battery-powered light trap. It was found that fluorescent lamps emitting UV radiation, such as: Philips TL Actinic BL (Hg) 15 W, Philips Actinic BL (Hg) 15 W and Philips TL BLB 18 W showed good suitability for catching O. nubilalis moths. Of these fluorescent lamps, the Philips TL Actinic BL (Hg) 15 W turned out to be the best. The comparison lamp powered by high-power mains electricity (Osram 250 W mercury bulb) was the most effective but required access to 230 V electricity.
