Antimicrobial activity of pimpinella anisum and foeniculum vulgare essential oils against paenibacillus larvae / Liesel B. Gende in The journal of essential oil research, Vol. 21 N°1 (Janvier/Février 2009)

(green anise) and Foeniculum vulgare Miller (fennel) were analyzed by GC and GC/MS and physicochemical properties. The oils of P. anisum and F. vulgare were found to be especially rich in (E)-anethole, 96.3% and 92.7%, respectively. The MICs were determined by the tube dilution method against Paenibacillus larvae. The oils showed MICs values were 300 mg/ mL and 250 mg/mL for P. anisum and F. vulgare, respectively. Both oils presented great similarity in physiochemical properties values and antimicrobial activity.

Laboratory evaluations of syzygium aromaticum (L.) merr. et perry essential oil against varroa destructor / Matias D. Maggi in The journal of essential oil research, Vol. 22 N° 2 (Mars/Avril 2010) 

Public ISBD [article]  in The journal of essential oil research > Vol. 22 N° 2 (Mars/Avril 2010) . - pp. 119-122 Titre : Laboratory evaluations of syzygium aromaticum (L.) merr. et perry essential oil against varroa destructor Type de document : texte imprimé Auteurs : Matias D. Maggi, Auteur ; Sergio R. Ruffinengo, Auteur ; Liesel B. Gende, Auteur Année de publication : 2010 Article en page(s) : pp. 119-122 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Syzygium  aromaticum  Myrtaceae  Essential  oil  composition  Eugenol  Mite  lethality  test  Apis  mellifera  Varroa  destructor Index. décimale : 646 Résumé : The oil obtained by hydrodistillation of the floral bottom of Syzygium aromaticum (L.) Merr. et Perry was analyzed by GC and GC/MS. Eugenol was the main constituent in the oil (86.7%). The biological activity of the oil applied to Varroa destructor and Apis mellifera was evaluated in two laboratory tests. Mite lethality was estimated using a complete exposure method test with the oil at different concentrations, and a systemic administration method of oil at different concentrations diluted in syrup was placed in feeders for bees. The LC50 for complete exposure method at 24 h was 0.59 mL/dish. The inferior and superior limits obtained were 0.47 x 10-6 mL/dish and 1.22 mL/dish, respectively. LC50 estimated at 48 h showed a slight decrease as compared to that recorded at 24 h. Ratio selection (LC50 of A. mellifera/ LC50 of V. destructor) for complete exposure method was 26.46 and 13.35 for 24 h and 48 h, respectively. Regarding the systemic administration method, mites LC50 at 24 h was 12,300 ppm. The inferior and superior limits calculated were 9,214 ppm and 15,178 ppm, respectively. LC50 estimated at 48 h showed a slight decrease as compared to that recorded at 24 h. Ratio selection for systemic administration method was 3.05 and 2.22 for 24 h and 48 h, respectively. Syzygium aromaticum oil was found to be an attractant for V. destructor at 4.8% (w/w) concentration. The results showed that oil toxicity against V. destructor differed depending upon its administration. Nevertheless, the ratio selection calculated by this oil is expected to enable its application under field conditions with a good safety margin. This oil could also be used in combination with other oils in integrated pest management strategies in bee colonies.
