Visual analysis of research on insect gut microbiota based on VOSviewer and CiteSpace

Abstract:

[Background] In recent years, the gut microbiology of insects has received extensive attention from researchers, and a large number of research papers and works have been published. However, the systematic bibliometric analysis of insect gut microbiota remains to be carried out. [Objective] To understand the history, hotspots, and trends of the research on insect gut microbiota at home and abroad. [Methods] We searched the China National Knowledge Infrastructure (CNKI) and Web of Science (WOS) with insect gut microbiota as the topic, and analyzed the keywords using the bibliometric tools VOSviewer and CiteSpace. [Results] The global research publications in this field showed an increasing trend during 1991–2022, and the research focuses and directions gradually expanded. The keyword clustering anchored three emerging research areas: insect meal, secondary metabolites, and biodegradation. [Conclusion] Bibliometric studies provide a rapid and intuitive understanding of the foundations, frontiers, and trends of the research on insect gut microbiota.
