The UK has a protected zone in place for this pest which helps to mitigate the risk of entry and establishment. An EFSA opinion is currently being discussed at the EU Annexes Working Group which recommends further strengthening of the regulation.
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.
