Abstract:

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.

Key words: Spodoptera litura, pest, CiteSpace, control
