In Australia, quarantine regulations are in place to restrict movement of potential “carriers” from infested areas. Carriers include vineyard personnel, grape products, grapevine material, machinery and equipment. Several strains of phylloxera have been detected in Australian Phylloxera Infested Zones and the strains have been shown to differ in their virulence characteristics, and response to chemical and heat disinfestation treatments. This study will highlight the significance of phylloxera genetic strains in the current management strategies. Latest findings on the relative sensitivity of genetically diverse phylloxera strains to chemical and heat disinfestation treatments will be presented</td></tr></tbody></table>
