Research hotspots and trend analysis of agricultural insects and pest control in China
The discipline of agricultural insects and pest control is a secondary branch of plant protection.In this paper,we examined the research hotspots,current focuses,and development trends of this discipline from the perspective of Chinese graduate dissertations.We aim is to provide a theoretical basis for the construction of this discipline and the high-quality development of agriculture in China.A total of 5746 relevant postgraduate dissertations published between 2000 and 2022 were retrieved from the China National Knowledge Infrastructure(CNKI)database.These were subjected to a visualization analysis,with a knowledge graph created using the CiteSpace software.The results showed an initial increase followed by a decline in the number of dissertations related to agricultural insects and pest control.the keyword co-occurrence analysis found that this discipline focused on major agricultural pests such as cotton bollworm(Helicoverpa armigera),brown planthopper(Nilaparvata lugens),rice stem borer(Chilo suppressalis),diamondback moth(Plutella xylostella),and tobacco whitefly(Bemisia tabaci).The keyword clustering analysis revealed that the research focused on 13 thematic areas,including gene cloning,phylogeny,and transcriptome.The burst keywords analysis indicated that transcriptomics,reproduction,and symbiotic bacteria will become future research trends.This paper provides a thorough examination of the current research hotspots and progress in the discipline of agricultural insects and pest control in China,and these results will serve as a valuable reference for future scholars seeking to improve their research in this field.
