The aim of this work was to ascertain the influence of applying various doses of organic fertilizers on the occurrence of the Carabidae and Staphylinidae families. The research was carried out in five treatments: 1) control treatment, 2) 25 t ha⁻¹ of farmyard manure, 3) 50 t ha⁻¹ of bio-sludge, 4) 50 t ha⁻¹ of farmyard manure, and 5) 100 t ha⁻¹ of bio-sludge. Coleoptera was represented by 87,324 individuals, Carabidae with a dominance of 80.53 to 86.28%, and Staphylinidae from 5.36 to 8.32%. Carabidae recorded the highest number for the 5th treatment, for 16,534 individuals, with the lowest number being for the 4th treatment, for 12,322 individuals. Staphylinidae recorded the highest number for the 4th treatment, with a frequency of 1,273 individuals, and the lowest number was for the 2nd treatment, with 934 individuals. When considering the crops grown that produce convenient individual conditions, crops producing shading, Helianthus annuus and Zea mays were preferred. The statistical evaluation did not confirm the effect of treatments, temperature, precipitation, and year of the occurrence of Carabidae. The effect of the treatment was not confirmed statistically in Staphylinidae, and the impact of the year, temperature, and precipitation were significant.
