General biosecurity comments

Pest of poplar; native to East Asia. Likely to be damaging if introduced to the UK. Protecting against the risk of entry via wood packaging material and other means remains a priority. A Europe-wide assessment would be helpful; to consider strengthened regulation.

Polyphagous moth pest whose larvae feed off a range of herbaceous and woody hosts. Native to East Asia where substantial impacts have been observed; and current import requirements do not fully mitigate the risk of introduction. A PRA will help to assess the level of risk more fully.

About this section

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.
