The direct toxicity of four essential oils, Majorana hortensis Moench, Rosmarinus officinalis L., Mentha piperita L. and Lavandula officinalis Chaix, to adult females of the predacious mite Amblyseius swirskii Athias-Henriot were tested. Peppermint oil was the most toxic to females A. swiriskii while the French lavender oil was the least toxic to the predator. All essential oils, at the two concentrations used, decreased the food consumption rate as well as egg laying. All four materials tested, at concentration 0.25% were considered to be safe for the predator since no mortalities had been recorded.
