A glasshouse pot trial evaluated the ability of the margarodid Eumargarodes laingi Jakubski to colonize sugarcane roots in six Bundaberg soil types. Soils from a sand to a clay supported pink ground pearls, but cyst numbers were significantly higher in silty clay loams. These findings have local quarantine implications used to minimize the spread of the pest.
