Sažetak

More than 100 species of nematodes are parasites of soybeans. Economically significant damages are encountered in each vegetation period worldwide. Root lesion nematodes (Pratylenchus spp.) are migratory endoparasites. High population of this pest can significantly reduce soybean yields. The aim of this study is to determine the species, population dynamics and reproductive index (RI) of root lesion nematodes in soybean. The study was carried out in Osijek area, from 2005 to 2007, on seven soybean cultivars. Population of root lesion nematodes was increasing during the vegetation. Since RI was positive, all cultivars proved to be good hosts. Two root lesion nematodes were determined: P. thornei and P. scribneri. The results indicate the need for continuous monitoring of root lesion nematodes in soybean.
