NAME OF THE ORGANISM: Bruchus atomarius (BRCHAT)
GENERAL INFORMATION ON THE PEST
Name as submitted in the project specification (if different to the preferred name):
1- Identity of the pest/Level of taxonomic listing:
Is the organism clearly a single taxonomic entity and can it be adequately distinguished from other entities of the same rank?
Is the pest defined at the species level or lower?:
Can listing of the pest at a taxonomic level higher than species be supported by scientific reasons or can species be identified within the taxonomic rank which are the (main) pests of concern?
- Not relevant: Vegetable seed sector
Is it justified that the pest is listed at a taxonomic rank below species level?
- Candidate: Vegetable seed sector
2 – Status in the EU:
Is this pest already a quarantine pest for the whole EU?
Presence in the EU:
Justification (if necessary):
The pest is present in most EU Member States (Fauna Europaea, 2017).
HOST PLANT N°1: Vicia faba (VICFX) for the Vegetable seed sector.
Origin of the listing:
1 - Vegetable seed sector: Council Directive 2002/55/EC
Plants for planting:
3 - Is the pest already listed in a PM4 standard on the concerned host plant?
4 - Are the listed plants for planting the main* pathway for the "pest/host/intended use" combination? (*: significant compared to others):
Only one record to B. atomarius (L.) on V. faba was found, in the field and in stored domestic production of Vicia faba beans in DE (Bahr, 1976). Assuming this record was of larvae or adults feeding inside the seed, (it does not state) then seed can be considered as a pathway. However as this is the only record, experts considered that Vicia faba is a rare or unusual host and thus rarely affected.
CONCLUSION ON THE STATUS:
Disqualified: Vicia faba is considered to be a rare or unusual host and thus rarely affected.
