Blastopsylla occidentalis

Eucalyptus shoot psyllid

Description

Blastopsylla occidentalis, commonly known as the eucalyptus shoot psyllid, is a sap-sucking insect native to Australia that primarily infests eucalyptus species. Since its introduction to other regions, it has been reported in parts of Europe, including Italy, Turkey, Spain, Portugal, Israel, and Malta. Both nymphs and adults feed on the sap of young shoots and leaves, leading to leaf curling, shoot distortion, and stunted growth. Severe infestations can cause significant defoliation, reducing the aesthetic value and overall health of eucalyptus trees. Additionally, the psyllids excrete honeydew, which promotes the growth of sooty mold, further diminishing the tree's appearance.

Symptom

Infested shoots and leaves exhibit curling, distortion, and stunted growth. Presence of honeydew can lead to sooty mold development.
