Present study is a part of the project focused on the environmental impact of GM maize MON 88017. Our aim was to assess the occurrence, abundance and distribution of entomopathogenic nematodes and their insect hosts in the experimental field with MON 88017 GM maize and non GM cultivars. Steinernema affine was present in all maize cultivars and the most important factor affecting it’s occurrence was probably type of the neighboring environment, as EPNs were only present in plots in the part of the field neighboring with a forest, regardless of the maize cultivar. Thus no effect maize MON 88017 on EPN distribution was revealed. The overall EPN density was quite low, probably reflecting the low density of soil insects. Thus the biocontrol potential of such a population would be limited.
