Abstract

Seed lots of tomato and capsicum ( and , respectively) are required to be free of quarantine pests before their entry to Australia is permitted. Testing of samples from 118 larger seed lots in the period 2019-2021 revealed that 31 (26.3%) carried one or more of four species, including tomato mottle mosaic virus (ToMMV), which is a quarantine pest for Australia. Testing of samples from a further 659 smaller seed lots showed that 123 (18.7%) carried a total of five species, including ToMMV and tomato brown rugose fruit virus (ToBRFV), which is also a quarantine pest for Australia. Estimated prevalence of contamination by tobamoviruses ranged from 0.388% to 0.004% in contaminated larger seed lots. Analyses of these data allow us to estimate probabilities of detection of contamination under different regulatory settings.

摘要

番茄和辣椒（分别为和）的种子批在获准进入澳大利亚之前，必须不带检疫性有害生物。2019-2021 年期间，对 118 批较大种子批的样本进行了检测，结果显示，有 31 批（26.3%）携带了番茄斑萎病毒（ToMMV）等 4 种中的一种或多种，而 ToMMV 是澳大利亚的检疫性有害生物。对另外 659 批较小种子批的样本进行检测，结果显示有 123 批（18.7%）共携带了 5 种，包括 ToMMV 和番茄褐色皱果病毒（ToBRFV），后者也是澳大利亚的检疫性有害生物。在受污染的较大种子批中，ToBamovirus 的污染率估计在 0.388%至 0.004%之间。对这些数据的分析使我们能够估计在不同监管环境下检测污染的概率。
