Abstract: The aim of the present study was to establish the efficacy of Salvia officinalis L. (Lamiales; Lamiaceae) essential oil against Myzus persicae Sulzer (Hemiptera; Aphididae) and its relationship to Apis mellifera L. (Hymenoptera; Apidae). The effect of the oil used in three different concentrations to control aphids has been studied. The concentration with the highest efficiency was tested for reaction in representatives of the indifferent entomofauna - honey bees (A. mellifera). The experiment was performed under laboratory conditions, in triplicate. The efficiency of the oil in concentration of 2 ml/l against M. persicae was found - 53.1%. No efficacy was observed in concentration of 0.50 ml/l, and at 1.00 ml/l it was low - 22.5%. The results of the experimental and control groups regarding the application of S. officinalis essential oil in concentration of 2 ml/l on A. mellifera are relatively similar. The data show that no effect of oil on bees was observed in this concentration.
