| - Aphids need in their food high content of low molecular nitrogenous compounds, therefore improved nitrogen nutrition and namely over-fertilization of plants with nitrogen increase significantly their infestation with aphids. We examined the effect of sulfur (S) supply to nitrogen (N) on plant growth and reproduction of aphids, Aphis fabae on sugar beet (Beta vulgaris) and Rhopalosiphum padi on barley (Hordeum sativum). Plants were grown in constant cultivation conditions. Nitrogen in the form of ammonium nitrate and S in the form of sodium or ammonium sulfate were applied in different combinations into the soil before sowing. Both nutrients applied separately stimulated plant growth, but their effects were highly increased when applied simultaneously. Infestation with aphids correlated partly with intensity of plant growth and was higher on all fertilized plants. However on both crops it was the highest on variants where only nitrogen was supplied. Surprisingly the enhancement of single

- Mšice potřebují ve své potravě vysoký obsah nízkomolekulárních dusíkatých sloučenin, proto zlepšená výživa dusíkem a zvláště přehnojení rostlin dusíkem zvyšuje významně jejich napadení mšicemi. Byl zjišťován vliv přídavku síry (S) k dusíku (N) na růst rostlin a množení mšic, Aphis fabae na cukrovce (Beta vulgaris) a Rhopalosiphum padi na ječmeni (Hordeum sativum). Rostliny byly pěstovány v konstantních kultivačních podmínkách. N a S byly aplikovány do půdy před setím v různých kombinacích ve formě dusičnanu amonného a síranu sodného a amonného. Obě živiny aplikované samostatně stimulovaly růst rostlin, jejich efekt se ale významně zvýšil při současné aplikaci. Napadení rostlin mšicemi korelovalo částečně s intenzitou růstu rostlin a bylo proto vyšší na všech přihnojených variantách. Na obou plodinách byly ale nejvíce napadeny varianty přihnojené samotným dusíkem. Překvapivě, předávkování dusíku nezvyšovalo dále počet mšic na rostlinách. Přídavek S k N u snižoval.napadení mšicí u obou plo (cs)
