The aim of this work is to validate the preexisting models that relate the larvicidal and adulticidal activities of the Eucalyptus essential oils on Aedes aegypti. Previous works at our laboratory described that the larvicidal activity of Eucalyptus essential oils can be estimated from the relative concentration of two main components (p-cymene and 1,8-cineole) and that the adulticidal effectiveness can be explained, to a great extent, by the presence of large amounts of the component 1,8- cineole in it. In general, the results show that the higher adulticidal effect of essential oils the lower their larvicidal activity. Fresh leaves was harvested and distilled. Once the essential oil was obtained, the chemical composition was analysed, evaluating the biological activity of 15 species of the genus Eucalyptus (Eucalyptus badjensis Beuzev and Welch, Eucalyptus badjensis¡Ánitens, Eucalyptus benthamii Welch, Eucalyptus badjensis¡Ánitens, Eucalyptus benthamii Welch, Eucalyptus badjensis¡Ánitens, Eucalyptus benthamii Welch, Eucalyptus badjensis¡Ánitens, Eucalyptus benthamii Welch, Eucalyptus badjensis¡Ánitens, Eucalyptus benthamii Welch, Eucalyptus badjensis¡Ánitens, Eucalyptus benthamii Welch, Eucalyptus badjensis¡Ánitens, Eucalyptus benthamii Welch, Eucalyptus badjensis¡Ánitens, Eucalyptus benthamii Welch, Eucalyptus badjensis¡Ánitens, Eucalyptus benthamii adulticidal effectiveness can be explained, to a great extent, by the presence of large amounts of the component 1,8- cineole in it.
