Thrips present in Africa; the Caribbean and parts of Asia; frequently intercepted in the UK. Can cause significant damage to tomatoes and other crops in countries where it is present. Europe wide PRA will consider its potential to establish and cause damage.
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.
