Habitats:Origin and History:
Loss of sap results in wilting, stunting die back and distortion. Sooty mould may grow on honey dew after heavy infestations. Spreads plant mycoplasma diseases. Feed on xylem or phloem.
Management and Control:Epidemics often controlled by hot or cold weather. Contact sprays and trunk injection of pesticides are often used.
Related Species:Aphids, Lerps, various 'bugs' leafhoppers and scales.
