|Publication abstract=''Aedes albopictus'' (Diptera: Culicidae) has been one of the fastest spreading insects over the past 20 years. Its medical importance is due to the aggressive daytime human-biting behavior and the ability to vector many viruses, including dengue, LaCrosse, Eastern Equine encephalitis and West Nile viruses. In this research, the essential oils (EOs) extracted from fresh air dried leaves of ''Salvia dorisiana, S. longifolia,'' and ''S. sclarea'' (Lamiaceae) were evaluated for their repellent activity against ''A. albopictus'' by using the human-bait technique. The EOs chemical composition was also investigated, and EOs were divided in three different profiles on the basis of their chemical composition: EO with large amount of monoterpenes from ''S. sclarea'', EO rich in oxygenated sesquiterpenes from ''S. dorisiana,'' and ''S. longifolia'' EO characterized by similar percentages of monoterpenes and sesquiterpenes. The efficacy protection from ''S. dorisiana, S. longifolia,'' and ''S. sclarea'' EOs, at dosages ranging from 0.004 to 0.4 μL cm<sup>−2</sup> of skin, was evaluated during 120 min of observation. Results indicated that ''S. dorisiana, S. longifolia,'' and ''S. sclarea'' EOs had a significant repellent activity (RD<sub>50</sub> = 0.00035, 0.00049, and 0.00101 μL cm<sup>−2</sup>, respectively), with differences in repellency rates, as a function of oil, dosage, and observation time. S''. dorisiana'' was the most effective oil: at the two higher dosages, it gave almost complete protection (with a protective efficacy of 90.99% and 95.62%, respectively) for 90 min. The best protection time was achieved with ''S. dorisiana'' essential oil. It ranged from 9.2 to 92.4 min. Protection times of ''S. longifolia'' and ''S. sclarea'' oils ranged from 3.2 to 60 min, and from 3.6 to 64.2 min, respectively. Our findings clearly reveal that these EOs have a good repellent activity against ''A''. ''albopictus'', therefore they can be proposed to improve the efficacy of repellent formulations against the Asian tiger mosquito.
