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. A Europe-wide PRA will help inform the case for EU regulation. Premises involved in importing wood and host plants from Italy in particular; where official measures are not being taken; should source material carefully.
Our plants are under greater threat than ever before. There is increasing movement of plants and other material traded from an increasing variety of sources. This increases the chances of exotic pests arriving with imported goods and travellers, as well as by natural means. Shoot is working with Defra to help members to do their part in preventing the introduction and spread of invasive risks.
