Pest categorisation of the non‐EU phytoplasmas of tuber‐forming Solanum spp.

EFSA Journal, Volume 18, Issue 12, December 2020., 2020
Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest categorisation of four phytoplasmas of tuber‐forming Solanum spp. known to occur only outside the EU or having a limited presence in the EU. The only tuber‐forming species of Solanum reported to be phytoplasma infected is S. tuberosum.

Pest categorisation of beet necrotic yellow vein virus

EFSA Journal, Volume 18, Issue 12, December 2020., 2020
Abstract Following a request from the EU Commission, the Panel on Plant Health performed a categorisation of beet necrotic yellow vein virus (BNYVV), the causal agent of the sugar beet rhizomania disease. The virus is currently listed in Annex III as a protected zone (PZ) quarantine pest of the Commission Implementing Regulation (EU) 2019/2072.

Chemical thinning in blue spruce (Picea pungens Engelm.) stands and its effects on cambioxylophagous fauna

Journal of Forest Science, 2010
Chemical thinning was applied in blue spruce (Picea pungens Engelm.) stands by the application of Roundup Klasik and Garlon 4 EC. The thinning efficacy of Garlon 4 EC was negligible, while that of Roundup Klasik reached nearly 100% when the full strength

Pest categorisation of tomato leaf curl New Delhi virus

EFSA Journal, Volume 18, Issue 7, July 2020., 2020
Abstract Following a request from the European Commission, the Panel on Plant Health performed a pest categorisation on tomato leaf curl New Delhi virus (ToLCNDV). ToLCNDV is a well‐defined bipartite Begomovirus species, sometimes associated with satellite molecules. It is transmitted by Bemisia tabaci to a wide range of hosts. ToLCNDV is reported from

Increasing Spring Temperatures Advance Post‐Diapause Swarming and Prolong the Reproductive Period in the Bark Beetle Ips typographus

Journal of Applied Entomology, Volume 149, Issue 5, Page 725-736, June 2025.
ABSTRACT Diapause is a common strategy in insects to respond to reoccurring adverse events. The European spruce bark beetle Ips typographus is an important forest pest in Eurasia affecting spruce‐dominated forests by eruptive outbreaks, which are likely to become more frequent and severe in a changing climate.

Phenology of the spruce bark beetle Ips typographus in the UK under past, current and future climate conditions

PLANTS, PEOPLE, PLANET, Volume 7, Issue 1, Page 284-300, January 2025.
In 2018, a breeding population of the European spruce bark‐beetle, Ips typographus, was discovered in woodland in southeast England. Ips typographus is a major forest pest in continental Europe; however, despite previous findings at ports and sawmills, this was the first recorded infestation in the UK.
