Potato cyst nematodes (PCN), namely Globodera pallida, pose a significant threat to potato production worldwide. Accurately quantifying nematode population densities is crucial for effective management strategies. However, traditional detection methods are time-consuming and often imprecise. X-ray computed tomography (CT) offers high-resolution, non-destructive and three-dimensional (3D) imaging frequently used to visualise internal structures of objects, materials or biological tissues, allowing for detailed analysis of their composition, defects, and morphology. Here, we demonstrate the effectiveness of X-ray CT in detecting and quantifying PCN cysts in two different soil types. The ability to achieve 3D imaging and volume quantification of PCN cysts from soils allows accurate enumeration of their egg content. Combined with the potential to co-analyse other organisms within the same sample, we propose X-ray CT as an innovative tool for comprehensive soil health assessments and sustainable pest management in agriculture.
马铃薯胞囊线虫(PCN),即苍白球孢囊线虫,对全球马铃薯生产构成重大威胁。准确量化线虫种群密度对于有效的管理策略至关重要。然而,传统的检测方法既耗时又往往不准确。X射线计算机断层扫描(CT)提供高分辨率、无损和三维(3D)成像,常用于可视化物体、材料或生物组织的内部结构,从而能够对其组成、缺陷和形态进行详细分析。在此,我们展示了X射线CT在检测和量化两种不同土壤类型中PCN胞囊方面的有效性。从土壤中实现PCN胞囊的3D成像和体积量化的能力,可以准确计算其卵含量。结合对同一样本中其他生物进行共同分析的潜力,我们提出将X射线CT作为农业中综合土壤健康评估和可持续害虫管理的创新工具。
