After the detection of the myrtle rust pathogen, Austropuccinia psidii, in New Zealand, a biosecurity response was initiated, including a wide-spread surveillance programme. Through an intensive public awareness initiative, the general public was highly engaged in reporting myrtle rust infections and added significant value to the surveys by reporting first detections from most of the areas that are now known to be infected. During the first year of the response, Austropuccinia psidii was found in areas that were predicted to be at high infection risk in previous modelling studies. Significant surveillance resources were deployed to different parts of the country and the response surveillance team contributed to most of the new host species finds. Twenty -four species and six hybrids of Myrtaceae have been confirmed to be naturally infected by myrtle rust in New Zealand. Eleven of these are new host records globally and three were previously recorded only as experimental hosts.

在新西兰追逐桃金娘:入侵后第一年的宿主范围和分布

在新西兰检测到桃金娘锈病病原体 Austropuccinia psidii 后,启动了生物安全响应,包括广泛的监测计划。通过密集的公众意识倡议,公众高度参与报告桃金娘锈病感染,并通过报告目前已知感染的大多数地区的首次发现,为调查增加了重要价值。在响应的第一年,在之前的建模研究中预测为高感染风险的地区发现了 Austropuccinia psidii。大量监测资源被部署到该国不同地区,响应监测小组为大多数新宿主物种的发现做出了贡献。已确认桃金娘科的 24 个物种和 6 个杂交种在新西兰自然感染桃金娘锈病。其中 11 个是全球新的宿主记录,3 个以前仅作为实验宿主记录。
