Resumen de DNA typing of populations of phylloxera (Daktulosphaira vitifoliae (Fitch)) from Australian vineyards

Angela Corrie, Gregory A. Buchanan, Robyn van Heeswijck

• A comparative analysis of six populations of Daktulosphaira vitifoliae, the insect grape phylloxera, from Australia was made using the Random Amplified Polymorphic DNA typing technique. The populations analysed fell into three distinct groups with similarity between groups ranging from 48% to 86%. The significance of these groupings is discussed with reference to the history of phylloxera in Australia, recommendations on rootstock use and quarantine.
