Summary
Chickpea chlorotic dwarf virus (CpCDV) is a potential Union quarantine pest not yet present in the EU. It infects various plants and can cause significant yield loss, posing a risk to agriculture.
Area of Science:
- Plant Virology
- Agricultural Entomology
- Pest Risk Assessment
Background:
- Chickpea chlorotic dwarf virus (CpCDV), a Mastrevirus, has been reported in Africa, Asia, and Oceania.
- CpCDV affects numerous plant families, including Fabaceae, and can cause severe yield reductions.
Purpose of the Study:
- To conduct a pest categorisation of CpCDV for the EU territory.
- To assess the risk of CpCDV entry, establishment, and impact on the EU.
Main Methods:
- Review of available scientific literature and data on CpCDV biology, host range, and transmission.
- Identification of potential entry pathways and assessment of its presence in the EU.
- Evaluation against criteria for a potential Union quarantine pest.
Main Results:
- CpCDV is not currently reported in the EU but has a wide host range, including weeds.
- Transmission occurs via leafhoppers, with *Orosius orientalis* present in some EU member states.
- Plants for planting and viruliferous leafhoppers are key entry pathways.
Conclusions:
- CpCDV poses a significant risk to EU agriculture due to its potential for entry, establishment, and impact.
- Phytosanitary measures can prevent its spread, and it meets criteria for a potential Union quarantine pest.
