Latest pests and diseases added to the Plant Health Risk Register

A new tree pest and new tree disease is among recent additions to the Plant Health Risk Register.

The pests and diseases include: 

  • Scolytus ventralis - the white fir engraver, a bark beetle pest of firs native to North America.
  • Gymnosporangium yamadae - a rust of apple and juniper species native to East Africa.

Pests recently reviewed on the Risk Register are:

  • Aceria kuko, a mite of goji berries now eradicated from the UK;
  • Echinothrips americanus, a thrips pest of several ornamental species grown in protected cultivation;
  • Chorisoneura conflictana, the Aspen borer-a defoliating moth of tree species in North American forests;
  • Agrilus convexicollis, a European jewel beetle of ash species widespread in Europe but not yet in the UK.

APHA is also warning about the Eastern cherry fruit fly, Rhagoletis cingulata, introduced to Europe in the 1980s. In the UK, the pest's damage could be mistaken for damage caused by spotted winged drosophilia.

Plant Health and Seeds Inspectorate (PHSI) has requested reports of these and any other non-indigenous plant pests.
