The direct toxicity of two essential oils,Majorana hortensis,Moench and Rosmarinus officinalis L.to adult females of the predacious mites,Amblyseius zaheri Yousef and El-Borolossy,Amblyseius barkeri (Hughes)and Typhlodromus athiasae Porath and Swirski were tested.Rosemary oil was the most toxic to fe- males of A.barkeri and the least to A.zaheri.In contrast,sweet marjoram oil was relatively toxic to T.athiasae and slightly toxic to A.barkeri.Both essential oils,decreased the food consumption rate at the concentration used for A.barkeri and A.zaheri.Females of A.barkeri and A.zaheri suffered a depression in reproduction when treated with 1% of rosemary oil.Both material used seems to be harmless to T.athiasae at 1%.
