The application of different combinations of mineral fertilizers had no significant influence on wheat entomofauna. The insect species in the trial plot detected were uniformly represented except for grain aphids whose number varied significantly. Numerous colonies of Sitobion avenae and Metopolophium dirhodum were estimated following the spring treatment employing highest nitrogen application amount (285 kg/h KAN). Greatest leaf damage caused by cereal leaf beetle (Lema melanogaster L.) larvae amounted to 21.7 and has been recorded following the use of an optimal NPK application rate, whereby the nitrogen-containing fertilizer had been employed in spring treatment.
