Summary
The Massonian pine bast scale, Matsucoccus massonianae, is a potential quarantine pest for the EU. While current import restrictions limit entry, its establishment is possible in suitable climates, posing a threat to pine trees.
Area of Science:
- Plant Health
- Entomology
- Pest Risk Analysis
Background:
- Matsucoccus massonianae, the Massonian pine bast scale, is a pest native to western China.
- It infests Pinus massoniana and Pinus thunbergii, ornamental trees found in the EU.
- The Matsucoccus genus includes species with a broad host range among Pinus species.
Purpose of the Study:
- To perform a pest categorisation of Matsucoccus massonianae for the EU territory.
- To assess its potential as a Union quarantine pest.
Main Methods:
- Review of existing data on M. massonianae biology, host range, and distribution.
- Assessment of potential entry pathways and establishment conditions in the EU.
- Evaluation against EFSA's criteria for Union quarantine pests.
Main Results:
- M. massonianae has a single generation per year, with all life stages on host trees.
- Infestations cause needle yellowing, early needle drop, shoot desiccation, and bark necrosis, particularly in older trees.
- While import pathways are currently restricted, suitable climatic conditions for establishment exist in parts of the southern EU.
Conclusions:
- Matsucoccus massonianae meets the criteria for a potential Union quarantine pest.
- Uncertainty remains regarding the full extent of its potential host range and impact if introduced.
- Current import prohibitions on Pinus from non-European countries mitigate immediate risk, but vigilance is needed.
