Bacillus thuringiensis pesticidal toxins: A global analysis based on a scientometric study (1980-2021)

Several studies have been conducted on Bacillus thuringiensis (Bt) pesticidal toxins due to their successful environmentally friendly biopesticide activity against various insect pest orders, protozoa, mites, and nematodes. However, no existing study has systematically examined the trends and evolution of research on Bt pesticidal toxins from a scientometric perspective. This study aimed to analyze the trends and hotspots of global research in this field. 5757 publications on Bt pesticidal toxins were extracted from the Web of Science Core Collection (WoS) from 1980 to 2021. Statistical and scientometric analyses were performed using Excel, CiteSpace, and VOSviewer visualization tools to evaluate research evolution, journal contribution and subject categories, contributing countries and institutions, highly influential references, and most used author keywords. The 5757 publications featured in 917 journals spanning 116 subject categories. The top 5 subject categories ranked as Entomology, Biotechnology & Applied Microbiology, Microbiology, Biochemistry & Molecular Biology, and Agriculture. Out of these publications, the USA contributed the most, with 1562 publications, 72,754 citations, and 46.58 average citations per paper (ACPP); however, Belgium had the highest (106.43) ACPP among the top 20 contributing countries. The Chinese Academy of Agricultural Sciences is the leading institution with 298 publications and 21.20 ACPP. The Pasteur Institute is ranked first (90.04) in terms of ACPP. Keywords analyses revealed that recent studies are inclined toward the evolution of insect resistance against Bt toxins. In future, studies related to the development of resistance mechanisms by insects against Bt pesticidal toxins and ways to overcome them will likely receive more attention. This study highlights the past and current situations and prospective directions of Bt pesticidal toxins-related research.

Visualization Analysis of Medicinal Mushrooms Research Topic Based on Web of Science

This study analyzed 1,739 papers on medicinal mushrooms published from 1999 to July 18, 2022 based on Web of Science (WoS). Papers were mainly written in English (1,733, 99.655%), from 6,502 authors, 92 countries or territories, 1,862 organizations and published in 311 journals and 3 book series. International Journal of Medicinal Mushrooms published 1,069 (61.472%) papers. Top 5 countries or regions were P.R. China, India, Taiwan, USA, and Malaysia; each published more than 87 papers. From the average citations, papers from Ukraine, Israel, Netherlands, Serbia, and Thailand show the highest citations per paper (more than 22.9 times per paper). The top five affiliations were Chinese Academy of Sciences, University of Malaya, University of Haifa, National Chung Hsing University, and Shanghai Academy of Agricultural Sciences, each with more than 49 papers. Top five authors are Wasser SP, Hyde KD, Mau JL, Sabaratnam V, Yang Y; each published more than 26 papers. The paper with the most was Wasser SP in Applied Microbiology and Biotechnology (2002), which has 1442 citations and the average number of citations is 68.67 times per year. Based on the ESI database, there are 13 top papers with 13 highly cited papers and 1 hot paper. All keywords in medicinal mushrooms research were separated into ten clusters according to different research topics. The results will help researchers clarify the current situation and provide guidance for future research.
