The tested concentrations of the experimental mixture were 1% of thyme (Thymus vulgaris L.) and 0.5% of sage (Salvia officinalis L.). These products were also injected into each colony by the aerosol way for one minute. 4 applications in an interval of 3 or 4 cays constitute the treatment. The dead mites (Varroa jacobsoni Oud.) were counted everyday. The number of surviving mites was estimated by means of a fluvalinate control treatment. No difference in the global efficiency was found for the moderately infested colonies (less than 1300 mites, a few mutilated pupae), which contained a small brood area. A weak grade of post-therapeutic residues in honey was only detected by gas chromatography just after aerosol administration1 aColin, M, E  uhttp://muse.lib.auth.gr:9797/com/csa/?MuseHost=www-mi2.csa.com&MuseFirst=1&id=2&recnum=6&SID=55360d1a6858ae31d3e80acbc52d3e6b&MusePath=/ids70/view_record.php
