草地贪夜蛾防控研究文献计量可视化分析

为系统分析草地贪夜蛾Spodoptera frugiperda当前的研究动态和方向,本文从Web of Science和CNKI中国知网下载相关数据,采用文献计量学方法对1920—2020年在国内外期刊上发表的1 222篇关于草地贪夜蛾防治的文献进行统计分析。当前草地贪夜蛾相关研究文献处于逐年上升的趋势;在外文文献中,草地贪夜蛾相关文献自20世纪80年代以来,发文量呈井喷式增长,主要出自美国、巴西、墨西哥等美洲国家,占比超过60%,相关高水平和有影响力的文献主要出自美国、英国、法国等西方发达国家,研究热点主要是草地贪夜蛾与其主要寄主作物玉米以及苏云金芽胞杆菌Bacillus thuringiensis、杆状病毒、真菌和转基因玉米等生防作用物之间的关系。草地贪夜蛾自2019年1月入侵我国后,国内关于草地贪夜蛾防治的文献迅速增加,中文文献有148篇,但在国际性期刊上发表的文献较少,研究内容主要以生防作用物、应急化学农药及主要为害作物玉米为对象。计量分析结果可为我国草地贪夜蛾的研究及绿色高效防治技术研发提供思路和方法。

Bibliometric visual analysis of literatures on the fall armyworm, Spodoptera frugiperda

In order to systematically analyze the research trend and direction on the fall armyworm, Spodoptera frugiperda, a statistical analysis of 1 222 literatures on the data of S. frugiperda published in domestic and foreign journals from 1920 to 2020 was performed by employing the method of bibliometrics in the public databases CNKI and Web of Science. The results showed that the literatures on this pest had increased for years. For foreign literatures, the papers related to this pest has experienced a blowout growth since 1980s, mainly from American countries (the United States, Brazil, Mexico, etc.), accounting for more than 60% of the total. The relevant influential papers were mainly from western developed countries (the United States, United Kingdom, France, etc.). The research hotspots were focused on the relationship among S. frugiperda, its main host plant (maize) and the biological agents such as Bacillus thuringiensis, baculovirus, fungus, transgenic maize and so on. Since S. frugiperda invaded China and caused harm in January 2019, the literatures on the prevention and control of S. frugiperda has increased greatly. The number of Chinese literatures was 148 in 2019, among which the number of papers published in international journals was relatively small, mainly covering the topics of biocontrol agents, emergency chemical pesticides and the main target crop maize. The results of bibliometrics visual analysis can provide new ideas and methods for the environment-friendly and efficient control and research of S. frugiperda in China.
