The gum tree weevil is endemic to Australia where Eucalyptus trees are native. This and other related species in the genus Gonipterus are invasive pests of eucalyptus in Africa, South America, North America, and Europe, and were historically misidentified as G. scutellatus until researchers examined the DNA of the pest species in 2012 and determined that none of the pests were genuine G ...
The adult female injects a neat line of minute eggs in the epidermis of new leaf buds on eucalyptus trees. The leaf tissue may exude a whitish sap, which covers the oviposition site. Heavy wasp infestations can kill new buds on the trees. If the bud survives it develops a layer of corky tissue within one to two weeks of oviposition.
Most species of Eucalyptus are trees, often mallees, and a few are shrubs. Along with several other genera in the tribe Eucalypteae, including Corymbia and Angophora, they are commonly known as eucalypts or "gum trees". Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard, or stringy and leaves that have oil glands.
The leaves are greyish green in colour, the blade has a lanceolate shape and is 90 to 120 mm (3.5 to 4.7 in) in length and 15 to 20 millimetres (0.6 to 0.8 in) wide. The leaves are basally tapered, the petioles are quadrangular or narrowly flattened or channelled. [ 4 ]

E. crebra bark. Ironbark is a common name of a number of species in three taxonomic groups within the genus Eucalyptus that have dark, deeply furrowed bark. [1]Instead of being shed annually as in many of the other species of Eucalyptus, the dead bark accumulates on the trees, forming the fissures.
Known for its anti-inflammatory “cooling properties,” as Dr. Mobley describes it, eucalyptus oil comes from Australian-native eucalyptus trees. Ehrlich says that eucalyptus oil can be used ...
