Ctenarytaina eucalypti

Eucalyptus psyllid

Description

Ctenarytaina eucalypti, commonly known as the eucalyptus psyllid, is a small sap-sucking insect native to Australia that primarily infests eucalyptus species, especially Eucalyptus globulus and Eucalyptus pulverulenta. Since its accidental introduction to Europe, it has established populations in several countries, including the United Kingdom, Ireland, France, Spain, and Germany. Both nymphs and adults feed on the sap of young shoots and leaves, leading to leaf curling, discoloration, and stunted growth. Severe infestations can result in significant aesthetic damage and reduced vigor of ornamental eucalyptus trees. Additionally, the psyllids excrete honeydew, which promotes the growth of sooty mold, further diminishing the tree's appearance.

In some regions, it is considered a key pest of eucalyptus plantations.

Symptom

Infested shoots exhibit curled and discolored leaves, often accompanied by white waxy secretions and the presence of honeydew, leading to sooty mold development.
