Phylloxera warning signPhylloxera, an aphid-like root louse that destroys grapevines, devastated up to 70% of Europe’s vineyards at the end of the 19th century. It first appeared in Australia at Geelong in 1877. It spread north, being detected in New South Wales in 1884 and Queensland in 1910, destroying vineyards and devastating the industry.  South Australia, having banned movement of vine material in 1874, remained free of the pest. Western Australia and Tasmania also escaped infection.>Vincyclopedia
