NAME OF THE ORGANISM: Quadraspidiotus perniciosus (QUADPE)


Name as submitted in the project specification (if different to the preferred name):

Pest category:

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: Ornamental sector
Is it justified that the pest is listed at a taxonomic rank below species level?
Not relevant

  • Not evaluated: Ornamental sector
2 – Status in the EU:
Is this pest already a quarantine pest for the whole EU?

HOST PLANT N°1: Pyrus (1PYUG) for the Ornamental sector.

Not evaluated: This pest/host combination was not identified by any EU MS in the RNQP questionnaire as requiring a revision of current thresholds and or a revision of current management measures. This pest/host combination is listed in the EPPO PM 4 Standard on Malus, Pyrus and Prunus. However it was not identified by the experts of the ornamental SEWG as requiring specific tolerance levels and/or specific risk management measures. Experts recommended that this pest/host combination should be covered in the future by the 'substantially free from' requirement that will remain in the EU Marketing Directives for ornamentals.
