The aim of this study was to identify the allelopatic effect of the components of a mixture of essential oils (EO) contained in the buds and leaves of hazel (Corylus L.) on herbivores. We examined the effect of these compounds on the choice of plants of two different hazel cultivars by Phytoptus avellanae Nal. (filbert big bud mite) and Myzocallis coryli Goetze (filbert aphid), which are the most important pests of hazel in Poland and throughout the world. Our results show that plants of cv. ‘Mogulnus’ were more resistant than those of cv. ‘Barra’ to the feeding of mites and aphids in all study years. Using gas chromatography (GC) and GC/mass spectrometry methodology, we determined the qualitative and quantitative composition of EO in the buds and leaves of plants of these two hazel cultivars. The EO obtained from the analysed materials was a mixture of mono- and sesquiterpenes. The emission of volatile organic compounds from plants is known to repel or attract pests. The mixture of EO present in the hazel buds of cv. ‘Mogulus’, which is resistant to filbert big bud mite, was characterized by a high content of nerol, α-campholenol, methyl salicylate, spatulenol, β-caryophylene and δ-cadinene. In contrast, the leaves of this cultivar, colonized by filbert aphid but to a relatively small extent, contained greater quantities of nerol, α-campholenol, p-cymene, α-terpineol and germacrene D, than the leaves of cv. ‘Barra’, which is more accepted by aphids. However, the leaves of cv. ‘Barra’ were characterized by a considerably high content of menthol, limonene, isomenthone, methyl salicylate and L-menthone.
