The aim of the study was to evaluate the diversity of invertebrate groups in spring wheat cultivated in different crop production systems. The field experiment was established in 1994 in experimental plot at Agricultural Experimental Station of IUNG-PIB Kępa in Osiny. The research was conducted in 2014-2016 on spring wheat fields in organic, conventional and integrated systems. At designated points in each year of research, biological material was collected, using two methods: sweep net and pitfall traps. The number of invertebrates in each order was determined and compared, as well as the variety of orders. Simpson's diversity index and Shannon-Wiener's index were used to assess their diversity. In spring wheat, about two times more spiders and pollinating insects were found in organic system than in conventional and integrated systems. Beetles (Coleoptera) were the dominant group of invertebrates in spring wheat in all crop production systems. The highest values of the Simpson and Shannon-Wiener’s diversity indexes calculated for invertebrate orders were recorded in the organic system, while the smallest in the integrated system.
