Intense studies on Genus Eucalyptus essential oil composition have been published already (Nair et al, 2008; Gamal and Sabrin, 2007; Batista-Pereira et al, 2006; Sartorelli et al, 2006; Hedges and Wilkins, 1991; Bignell et al, 1998).

Abstract: In 1998 the eucalyptus weevil, Gonipterus scutellatus (Coleoptera: Curculionidae), a major defoliator of the genus Eucalyptus
, which causes growth and economic losses, was detected in Chile.
Two articles deal with allelopathy in Australian plants: one considers the important genus Eucalyptus
, long considered to be involved in allelopathic interactions.
Consequently, 8 of 10 species with lower SLA had more leaf nitrogen per unit area, the exceptions being in the genus Eucalyptus
(in which the divergence in SLA was only slight) and in the genus Olearia, which was the only rainfall PIC that also went against the general trend to lower SLA at low rainfall.
Instead, the pattern in total gall species richness can largely be explained by the fact that myrtaceous tree species (of the genus Eucalyptus
and the closely related genus Syncarpia) supported more gall species than other plant species (Fig.
The genus Eucalyptus
, comprised of over 700 different species, include some of the fastest growing woody plants in the world and, at approximately 18 million hectares in 90 countries, it is one of the most widely planted genus of plantation forest trees in the world.
One of these medicinal plants, many species of the genus Eucalyptus from the Myrtaceae family are used in many parts of the world for the treatment of a wide variety of diseases including microbial infections (Ben Arfa et al, 2007).
The essential oil constituents of the genus Eucalyptus (Myrtaceae) have been well characterized (Batista-Pereira et al, 2006) Eucalyptus species produce numerous volatile compounds in large amounts, especially isoprenoids (here referred to as terpenes), which are accumulated in glands abundantly distributed throughout the leaf parenchyma and bark.
