Pest categorisation of Diaphorina citri

EFSA Journal, Volume 19, Issue 1, January 2021., 2021
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Diaphorina citri (Hemiptera: Liviidae) (Asian citrus psyllid) for the EU. D. citri is a key pest of citrus in several countries as it is a vector of serious bacterial pathogens, the putative causal agents of Huanglongbing (HLB) also known as citrus greening.

Experimental host range of Citrus leprosis virus C (CiLV-C) [PDF]

Tropical Plant Pathology, 2014
Citrus leprosis (CL) is a serious threat to the citrus industry, especially for sweet oranges. For a long time, Citrus spp. were considered the only susceptible hosts. However, other plant species were also found either experimentally or naturally to be susceptible to Citrus leprosis virus C (CiLV-C).

Transmission of Citrus leprosis virus C by Brevipalpus phoenicis (Geijskes) to Alternative Host Plants Found in Citrus Orchards [PDF]

Plant Disease, 2012
The equivalent of US$75 million is spent each year in Brazil to control Brevipalpus phoenicis, a mite vector of Citrus leprosis virus C (CiLV-C). In this study, we investigated the possibility that hedgerows and windbreaks normally found in citrus orchards could host CiLV-C.

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.

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.
