General biosecurity comments

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

Based on its biology and low potential impact continued action on this pest in the UK would not be considered appropriate. It is likely to be of more concern to southern Member States of the EU; as it is an economic pest of citrus.

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.
