Fera has recently added a number of pests to the Risk Register. All of these pests were added due to their listing in the new Plant Health legislation which came into effect in December 2019. These pests were added in a different way to most new pests, in a series of workshops as part of Fera’s work reviewing the Risk Register in response to the new legislation.


Seven viruses, all vectored by Bemisia tabaci (with some also being vectored by other hemipteran insects)


Three viruses mainly affecting tomato:

Tomato chocolate virus

Tomato marchitez virus

Tomato mild mottle virus


Two viruses mainly affecting cucurbits:

Melon yellowing-associated virus

Squash vein yellowing virus


Two viruses affecting mainly sweet potato:

Sweet potato chlorotic stunt virus

Sweet potato mild mottle virus


Fera has also added seven species in a genus of tortricid moths, Acleris. All the species added to the RR this month feed on broadleaved trees and shrubs of various hosts, though other species in the genus feed on many other hosts.
