Abstract:

To understand the current research status of the sublethal effects of insecticides on pests, CiteSpace visualization analysis software was used to search for papers related to the theme of “sublethal effects” in WOS and CNKI databases. Knowledge maps were drawn and analyzed for the publication status, authors, countries, as well as research hotspots and trends of the papers. Research has shown that the publication situation in this field at home and abroad is relatively similar, showing an upward trend. The core authors of the publication have shown good cooperation and communication relationships, with close communication links between institutions. The United States has the greatest influence in this research field, while China is one of the main countries for international publication. The main publishing institutions in China are the Chinese Academy of Agricultural Sciences, the Chinese Academy of Tropical Agricultural Sciences, China Agricultural University, and Huazhong Agricultural University. At present, there are high-frequency words and clustering studies on sublethal effects both domestically and internationally around keywords such as “pesticide”, “insecticide”, and “toxicity”. The evolution process of hot topics is relatively similar. In the early stage, the research focused on sublethal research; in the middle stage, relevant explorations were conducted on the effects of different insecticides on the growth and development of pests; and in the later stage, many new research directions began to emerge, making research in this field more in-depth.
