为更全面了解当前斜纹夜蛾的研究现状,以中国知网(CNKI)数据库和WOS(Web of Science)数据库收录的斜纹夜蛾相关文献为对象,采用CiteSpace文献计量方法对比分析,分别从作者、机构和关键词3个方面绘制了可视化图表,对斜纹夜蛾演进趋势、研究热点进行了归纳总结.结果表明,国内外斜纹夜蛾的研究一直以防治为主.近年来,中国对斜纹夜蛾的研究主要集中在防治过程中化学农药的不合理施用,导致土壤和环境的破坏,并诱导斜纹夜蛾进化出了抗性机制.在提倡无公害、绿色有机的大背景下,关于斜纹夜蛾的防治措施多趋向生物防治,而国外的研究多注重其内部结构及病毒杀虫剂.由此,当前对于斜纹夜蛾的研究主要分为两部分,一为生物和化学防治的结合,研究出高效低污染的防治手段或杀虫剂;二为斜纹夜蛾生长发育和内部构造的研究,在不破坏生物多样性的前提下,降低害虫的种群数量,减少危害.
Research Progress and Hotspot Visualization Analysis of Agricultural Pest Spodoptera litura Based on CiteSpace
To better understand the current research status of Spodoptera litura,taking the relevant literatures of Spodoptera litura collected in CNKI(China National Knowledge Infrastructure)database and WOS(Web of Science)database as the object,the CiteSpace bibliometric method was used to compare and analyze,and visual charts were drawn from three aspects of author,organization and keywords,respectively,to summarize the evolution trend and research hotspots of Spodoptera litura.The research shows that the control of Spodoptera litura has been the main research at home and abroad.In recent years,China's research on Spodoptera litura has mainly focused on the unreasonable application of chemical pesticides in the control process,which leads to soil and environmental damage and induces the evolution of resistance mechanisms in Spodoptera litura.Under the background of advocating pollution-free,green and organic,the control measures of Spodoptera litura tend to biological control,while foreign research focuses on its internal structure and viral pesticides.To sum up,the current research on Spodoptera litura is mainly divided into two parts.One is the combination of biological and chemical control to develop efficient and low pollution control methods or pesticides.The other is the research on the growth,development and internal structure of Spodoptera litura,reducing the population number of certain pests and reducing the harm without destroying biodiversity.
