General Comments

Ambrosia beetle which can affect a wide range of broadleaved trees, widespread in Africa, Asia and parts of the US, with outbreaks in France and Italy. The UK climate is unlikely to be suitable for the pest to thrive and cause significant damage but needs to be investigated through research. Premises involved in importing wood and host plants from Italy in particular, where official measures are not being taken, should source material carefully.
