Sažetak
Ground beetles (Coleoptera: Carabidae) are the largest family of adephagan beetles who are well known as good ecological indicators of environmental change. They have important role in natural pest-control due to their predatory polyphagous nutrition. Because of sensitivity to anthropogenic changes it is considered that they have bioindicative value. Also larvae are especially susceptible to tillage practices since their bodies are relatively soft. The aim of the study was to determine the effect of agro-technical measures (tillage, cropping history, soil cover and insecticide treatments) on the ground beetle abundance in different types of arable crops with respect to the prevailing weather conditions. The study was conducted in the north - eastern part of the Croatia. Samples were collected weekly, from May to September 2015, by using epigeic (pitfall traps) and endogenic traps. In total, 2, 730 ground beetles were collected. The number of collected ground beetles differs among investigated fields. The crop and cropping history strongly influence the abundance of both, soil surface and soil dwelling species. The highest captures were recorded on oilseed rape field, while the lowest on sugar beet field. This could be correlated with soil cover and insecticide seed treatment. Foliar application of insecticides did not influence the abundance of ground beetles.
