What is golden root mealybug?
Golden root mealybug is a sap feeding insect that feeds on the roots of a wide variety of plants, although it has mainly been found on Meconopsis and Primula in the Britain. Unlike most other mealybug species found in the Britain it is able to survive the winter outdoors.
The golden root mealybug is a recent arrival in the Britain, and has so far been found in Scotland and northern England. In 2019 it was reported from Northern Ireland. The RHS wants gardeners finding this insect in their garden to let them know by emailing images to the RHS Entomology Team. The postcode of the house/garden where the pest has been found should be given, along with the identity of the host plants, or if unknown an image of the foliage and flowers.
Submissions to our pest and disease surveys are stored permanently in an anonymised form in order to monitor the spread of the pest or disease. We may contact you within 2 months of your submission in order to verify your sighting but your personal data will not be permanently stored in connection with your submission and will be deleted after 1 year. We publish and share only non-identifiable data from survey submissions (such as a six figure grid reference) with third parties and the public for the purposes of scientific research and advancing understanding among gardeners.
