() is a plant pathogen which attacks vines, citrus fruits, olive, almond and several many other species, causing considerable economic losses. In the last few years has become a global threat after being a local problem for decades: while it was once known only in circumscribed regions of the Americas, in 2013 it began to devastate olive groves in Southern Italy, and its presence has also been reported in France, Spain, and Portugal. Even though has been under study since the late 1980s, the rapid worldwide spread raises the question of whether research infrastructure is adequately prepared to address new challenges, such as the need for novel methods to control and prevent infection, gaining a deeper understanding of its biology and life cycle to identify vulnerable intervention points, coordinating international responses to combat its spread, and mitigating impacts on crops and the agricultural environment. Using a bibliometric approach, this study tried to answer this question by tracing an overview of the evolution of literature from 1989 to present. The analysis was conducted on the Scopus database focusing separately on three periods (1989–1999; 2000–2010; 2011–2021). After a pioneering phase in 1989–1999, the intermediate period resulted the one with the highest scientific production, in which most currently ongoing research lines were started. The last period showed a revitalization of research after some years of decline, mostly due to the recent outbreak on olive in Europe, but it was characterized by a slower increment of topics with a growth of interconnection level among themes, indicating an ongoing process of consolidation of the established research lines. The authorship and thematic characterization demonstrated that research was shaped by a "geographical factor", which has represented a crucial element over time and continues to have an impact on how collaborations and topics are organized.

绘制围绕苛养木杆菌的科学图谱：意大利橄榄园疫情爆发后的最新情况


() 是一种植物病原体，它攻击葡萄树、柑橘类水果、橄榄、杏仁和许多其他物种，造成相当大的经济损失。几十年来，它一直是一个地方性问题，但在过去几年里，它已成为一个全球性威胁：虽然它曾经只在美洲的有限地区为人所知，但在 2013 年，它开始摧毁意大利南部的橄榄园，而且也有报道称它的存在法国、西班牙和葡萄牙。尽管自 20 世纪 80 年代末以来一直在进行研究，但它在全球范围内的迅速传播提出了一个问题：研究基础设施是否已做好充分准备来应对新的挑战，例如需要新的方法来控制和预防感染，从而更深入地了解其生物学和生命周期，以确定脆弱的干预点，协调国际应对措施以遏制其蔓延，并减轻对作物和农业环境的影响。本研究采用文献计量方法，试图通过追溯 1989 年至今的文献演变概述来回答这个问题。分析是在 Scopus 数据库上进行的，分别关注三个时期（1989-1999；2000-2010；2011-2021）。经过 1989 年至 1999 年的开拓阶段之后，中期阶段产生了最高的科学成果，目前大多数正在进行的研究线都在这个时期开始。上一时期的研究在经历了几年的下降后出现了复苏，主要是由于最近欧洲橄榄的爆发，但其特点是主题增量较慢，主题之间的互联程度有所提高，表明一个持续的整合过程已建立的研究线。 作者身份和主题特征表明，研究是由“地理因素”塑造的，随着时间的推移，它代表了一个关键因素，并继续对合作和主题的组织方式产生影响。
