摘要
Grapevine phylloxera Daktulosphaira vitifoliae Fitch (Hemiptera: Phylloxeridae) has been present in Australia for almost 150 years but has not spread to south‐west Western Australia, in part due to the relative isolation of the region. Recent improvements in tourist access, with interstate flights now arriving at Busselton Margaret River Airport, raise concerns about potential phylloxera introductions via wine tourism. In this paper, we simulate the potential economic impact on the Western Australian winegrape industry following a hypothetical arrival event in the Margaret River wine region. We use soil texture maps to assess the suitability of winegrape‐growing areas to phylloxera establishment and construct a model to predict the likely cost and revenue implications of replanting vines to resistant rootstock as they become infested. Our results suggest that if strict quarantine measures to limit spread are not implemented, a phylloxera incursion could affect 60%–70% of vines and cause cumulative losses of AUD150–290 million over a 50‐year period. This is equivalent to a 3%–6% annual contraction of winegrape production.

葡萄植素daktuloxera daktulospaira vitifoliae fitch（hemiptera：phylloxeridae）在澳大利亚已经存在了近150年，但尚未扩散到西澳大利亚州南部，部分原因是该地区的相对隔离。目前，州际航班到达玛格丽特河机场的州际航班的最新进步，引起了人们对通过葡萄酒旅游潜在介绍潜在介绍的担忧。在本文中，我们模拟了在玛格丽特河葡萄酒地区的一个假设到达事件之后，模拟了对西澳大利亚葡萄酒行业的潜在经济影响。我们使用土壤纹理图来评估葡萄酒葡萄酒生长区域对植物的适合性，并构建一个模型，以预测在侵扰时重新种植藤蔓以抵抗砧木的可能成本和收入的影响。我们的结果表明，如果未实施严格的隔离措施限制限制量，则在50年期间，浮游生物的入侵可能会影响60％–70％的葡萄藤，并在50年内造成150-2.29亿澳元的累积损失。这相当于葡萄酒葡萄酒生产的年收入3％–6％。
