Characterization of a Virus Infecting Citrus volkameriana with Citrus Leprosis-Like Symptoms [PDF]

Phytopathology®, 2012
A Citrus volkameriana tree displaying symptoms similar to citrus leprosis on its leaves and bark was found in Hawaii. Citrus leprosis virus C (CiLV-C)-specific detection assays, however, were negative for all tissues tested. Short, bacilliform virus-like particles were observed by transmission electron microscopy in the cytoplasm of symptomatic leaves

List of 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 prepared a list of non‐EU phytoplasmas of tuber‐forming Solanum spp. A systematic literature review and search of databases identified 12 phytoplasmas infecting S. tuberosum. These phytoplasmas were assigned to three categories.

A Simulation of the Use of High Throughput Sequencing as Pre-Screening Assay to Enhance the Surveillance of Citrus Viruses and Viroids in the EPPO Region

Agriculture, 2021
Citrus are affected by many viruses and viroids, some globally widespread and some restricted to particular countries or areas. In this study, we simulated the use of high throughput sequencing (HTS) and the bioinformatic analysis of small interfering ...

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 Leptinotarsa decemlineata

EFSA Journal, Volume 18, Issue 12, December 2020., 2020
Abstract The EFSA Panel on Plant Health performed a pest categorisation of the Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae) for the EU. L. decemlineata is primarily known as a major defoliator of potatoes (Solanum tuberosum); feeding damage can result in significant yield loss.

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.
