The psyllid Ctenarytaina eucalypti is endemic to Australia and has already been introduced repeatedly to Germany in recent years, but has obviously always been eradicated. In the EU, it has already been detected in France, Ireland, Italy, Portugal and Spain. So far, the psyllid is not listed in the Annexes of Regulation (EU) 2019/2072 or by EPPO..

Ctenarytaina eucalypti infests Eucalyptus.

Due to suitable climatic conditions, it is assumed that C. eucalypti can establish outdoors in moderate regions of Germany (at least temporarily), the establishment in south European EU-Member States is possible, too. Furthermore, presence resp. establishment in protected cultivation is possible.

Damage can be effectively contained by the calcyd wasp Psyllaephagus pilosus that has also been detected in Germany, so only a low overall potential for damage to eucalyptus plants in Germany and other EU-Member States is assumed. Therefore, Ctenarytaina eucalypti is not classified as a quarantine pest and Article 29 of Regulation (EU) 2016/2031 does not apply.
