摘要:The aim of the experiment was to determine the effect of aqueous extracts of dried sage (Salvia officinalis L.) in concentrations of 2%, 5% and 10%, and the fresh parts of the plant in concentrations of 10%, 20% and 30% on the feeding of Sitona lineatus L.on the broad bean (Vicia faba L.) leaves.The olfactometry response of the pest (response to olfactory stimuli) was also determined in relation to the sage.Extracts of dry and fresh parts of sage reveal the inhibitory effect on feeding of both males and females of pea leaf weevil, the stronger, the higher their concentrations, however, no apparent differences were registered between the analysed sexes.Dry plant extracts in 10% concentrations and 30% extracts of fresh sage parts caused 2–3 time reduction of Sitona lineatus feeding after 4 days of the experiment.An apparent repellent response of aroma substances originating from sage towards weevil beetles (both males and females) was registered, which suggests potential applications of this plant as a neighbouring plant in mixed stands or, e.g., as a component of border belts.
