  Wheat production is a determining branch within Hungarian crop production (produced on nearly one million hectares). Weather anomalies caused by climatic change confirmed the importance of the biological background (variety, hybrid) in wheat production. The adapting ability and reaction of different wheat genotypes towards nutrient supply were studied in a long-term field experiment on chernozem soil type in the case of different pre-crops (sunflower and maize). According to the experimental results of the vegetation of 2017/2018, the yield of the variety Ingenio sown after the sunflower as previous crop ranged between 4168 and 8734 kg ha^-1, while in the case of maize as previous crop, this value ranged between 2084 and 7782kg ha^-1, depending on the applied nutrient supply level. The studied genotypes produced rather significant yield surplus as a response to the application of mineral fertilization (4.6–5.1 t ha^-1 after sunflower and 5.7–6.3 t ha^-1 after maize). Optimal mineral fertilizer dosage was determined by both the genotype and the pre-crop. N-optimum values of wheat genotypes was determined using regression analysis. In the case of the variety Ingenio sown after sunflower, the optimum range was N_144-150+PK, while after maize, it was
  N_123-150+PK, respectively. For the hybrid Hyland, these optimum ranges were N_114-120+PK, just as N_150-153+PK, resp. The application of optimal mineral fertilizer dosages improved water utilization of the studied wheat genotypes to a significant extent. WUE values of the control, unfertilized treatments ranged between 4.1–8.3 kg mm^-1, while in optimal fertilizer treatment, it ranged between 15.5 and 17.4 kg mm^-1.

  The multicoloured Asian ladybird beetle (Harmonia axyridis (Pallas, 1773)), a former successful biological control agent in the USA and Western Europe became an invasive alien species threatening the diversity of native aphidophagous insects through competition and praying, a horticultural pest consuming various fruits and adversely affecting the wine quality and a human nuisance when occurring at high densities in buildings. Due to this dubious fame, attention has been paid to it also at national level which made inevitable to find for it a fitting name in different languages. In some cases and countries a version of the English name has been chosen however, regarding the meaning of this translated term in Hungarian, the try cannot be called fortunate. The objective of this contribution is to stress the function of common animal names in the Hungarian Sprachraum and to find a right and proper alternative with the help of etymology, mythology, classical literature, art (painting) and the experiences of Hungarian fruit and grape growers.
