• The effect of the application of insecticide FURY 10 EW (0.15 L ha−1) in winter rape on non-target indicator ground beetles (Coleoptera: Carabidae) was examined in a field experiment. The species composition, the dominance structure, the abundance and the diversity of ground beetles in pitfall traps was compared before and after the application of the insecticide during April 2009. In total, 128 specimens of 19 species of ground beetles was recorded. The community was dominated by Poecilus cupreus (61 % of total specimens) and it consisted of eurytopic carnivorous and granivorous species typical for intensively managed crop fields. No effect of the insecticide treatment on the community characteristics was observed. The Shannon diversity (H’) index was 1.5 and 1.6 before and after the insecticide application, respectively. The application of insecticide on well grown rape plants, which may have protected the soil surface from a contact with the insecticide, could be accounted for the leaving the ground beetles community intact.
