Sažetak
In the period 1972 - 1974 tentative analyses of plant-parasitic nematodes associated with root of corn plants were carried out under various climatic and soil conditions in the Republic of Bosnia and Herzegovina. The density of the nemetode populations examined varies considerably between the localities and the fields of the same locality as well as between the samples from the same field. The Pratylenchus species is present in all populations analysed with various absolute and relative numbers and the ratios between the species. Coparatively highest numbers of this species were established in the populations from the mediterranean climate (up to 1,500 individual per 100 gr of soil sample). P. crenatus Loff species is present, almost exclusively, in the conditions of acid soil (pH 4,5 - 5,0), P. thornei Sher-Allen is predominant in the conditions of sightly acid,-, and P. neglectus Fil. -Stekh.- in the conditions of alkaline soil. Besides the Pratylenchus species, spiral nematodes mostly Helicotylenchus spp., are among the most important ones in the populations from the continental climate, and Rotylenchulus borealis Loof-Oostenbrink and Meloidogyne species - from the mediterranean climate. It has been established that corn plants show host response towards R. borealis.
