Scientists have found diamondback moth (DBM) caterpillars surviving in UK Brassica crops this winter and are recommending growers check their own crops for the pest now.
Previously considered a migratory pest, recent research from AHDB indicated that diamondback moths could be surviving UK winters.
AHDB’s Dawn Teverson, and Rosemary Collier from Warwick Crop Centre have been out in the field hunting for the caterpillars and found the pest on the underside of leaves in un-netted swede crops, located in the south west of England.
