General biosecurity comments

Polyphagous moth pest from Eastern Asia which could be damaging to broadleaf and coniferous species if introduced to the UK; as well as having human health impacts. The main pathway is likely to be on goods (including non-plant material) imported from Eastern Asia and awareness raising with the main industry sectors is recommended.

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.
