The repellent and anti-feeding effect of garlic oil was evaluated in laboratory conditions against the bite of Phlebotomus papatasi females. The effectiveness was evaluated by two different laboratory procedures: (i) topical application of garlic oil on five human volunteers, using the "standard cage test", and (ii) feeding sandflies on artificial membranes treated with the compound. Garlic oil showed a significant protection by topical application on the skin of volunteers, being the protection 97% and 40%, respectively at 1% and 0.005% dilution. Garlic oil showed also an anti-feeding effect when tested on the artificial membrane feeding apparatus; the anti-feeding effect was dose dependent, being 100% at 1%. The results of the present study confirm previous observations on the repellent effect of garlic oil against haematophagous arthropods.
