Abstract

The repellent activity of Piper aduncum essential oil against Aedes albopictus was investigated under laboratory conditions with human volunteers. The lowest median effective dose (ED50) value was 1.5 g/cm2 at 60 sec of exposure when compared to 90 sec (2.1 g/cm2) and 120 sec (1.8 g/cm2) of exposure. At 0.4 g, the essential oil gave a high protection (95.2) against Ae. albopictus bites or landing at 2 h postapplication. The percentage of protection was reduced to 83.3 after 4 h, 64.5 after 6 h, and 51.6 after 8 h postapplication. As a comparison, treatment with 10 deet gave 100 protection against mosquito biting/landing for 4 h postapplication. There was no significant difference in percentage protection reduction between the plant extract and the commercial product deet, respectively (P 0.739). The essential oil, which was not as good as deet, still gave moderate protection against Ae. albopictus biting even until 4 h postapplication. In conclusion, the P. aduncum essential oil has the potential to be used as a repellent against the dengue/dengue hemorrhagic fever vector, Ae. albopictus.
