Our research was realised on spring barley and winter wheat in Nitra-Dolná Malanta during 2004–2006. We found that the total occurrence of the pests had decreasing tendency. The flea beetle (Phyllotreta), thrips (Thysanoptera) and cereal leaf beetle (Oulema gallaeciana) had the highest occurrences. More pests occurred on non-fertilised variants than on fertilised ones in 2004. During 2005 and 2006 there were more pests on the fertilised variants. The effect of fertilisation was the same for spring barley and winter wheat.
