Arabidopsis thaliana (Thale cress)

Common pest name

Cassava whitefly; Cotton whitefly; Sweet potato whitefly; Tobacco whitefly

Scientific pest name

Bemisia tabaci non-European populations

Type

Insect

Current status in UK

Absent

Likelihood to spread to UK (1 is very low - 5 is very high)

2

Impact (1 is very low - 5 is very high)

5

General biosecurity comments

Non-European populations of Bemisia tabaci pose an additional risk to European populations due to the potential for introducing non-European viruses.

Defra's Risk register #2

Plant name

Arabidopsis thaliana (Thale cress)

Common pest name

Lance nematode; Nematode; Lance

Scientific pest name

Hoplolaimus spp.

Type

Nematode

Absent

Likelihood to spread to UK (1 is very low - 5 is very high)

2

Impact (1 is very low - 5 is very high)

4

General biosecurity comments

Nematode species potentially affecting a wide variety of crops; prohibition of soil likely to mitigate risk substantially; keep under review in light of interceptions or findings should they occur in the EU.

General biosecurity comments

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.

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.
