Four light traps, containing blacklight and bluelight tubes, respectively, were placed at different distances from the stream bank. The most efficient was the light trap placed 10 m away, followed by the light trap at the stream bank and the light trap 50 m away. However, males of the most abundant species Potamophylaxcingulatus, which belonged to two subspecies, showed different distributional pattern. Among the used light traps, the one containing bluelight tube was less efficient than those with blacklight tubesOb vodotoku Poltarica je avtor opazoval vpliv vira svetlobe in oddaljenosti svetlobne pasti od vodotoka na ulov mladoletnic. Štiri svetlobne pasti so bilepostavijene na različnih oddaljenostih od brega vodotoka. Najučinkovitejšaje bila past v oddaljenosti 10 metrov, sledili pa sta ji past na bregu in past v oddaljenosti 50 metrov. Drugačna razporeditev osebkov je bila opažena pri samcih najpogostejše vrste Potamophylax cingulatus, ki so pripadali dvema različnima podvrstama. Svetlobna past z modrim virom svetlobe je bila manj učinkovita kot tiste z ultravijoličnimi viriTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza za tehnično kulturo Slovenije
