Ctenarytaina spatulata

Rose gum psyllid

Description

Ctenarytaina spatulata, commonly known as the rose gum psyllid, is a sap-sucking insect native to Australia that primarily infests eucalyptus species, especially Eucalyptus globulus and Eucalyptus camaldulensis. Since its introduction to other regions, it has been reported in parts of Europe, including Portugal. Both nymphs and adults feed on the sap of mature shoots, particularly in the apical parts of the tree, leading to small necrotic lesions, proliferation of lateral shoots, and leaf distortions. Infestations can result in significant aesthetic damage and reduced vigor of ornamental eucalyptus trees. Additionally, the psyllids excrete large amounts of honeydew, which promotes the growth of sooty molds, further diminishing the tree's appearance.

Symptom

Infested shoots exhibit small necrotic lesions, leaf distortions, and proliferation of lateral shoots. Presence of honeydew can lead to sooty mold development.
