Bibliographic and Research Gap Analysis on Herbivore Induced Plant Volatiles in Pest Management - A Case Study

The Herbivore Induced Plant Volatiles (HIPVs) are low molecular weight compounds and mostly belong to terpenoids, phenylpropanoids/benzenoids, Green Leaf Volatiles (GLVs) and amino acid derivatives. Volatile phytochemicals function as airborne indirect defense communication signals that specifically attract natural enemies. This case study discusses in detail metrics of publication on Herbivore Induced Plant Volatiles and pest management in the last two decades as listed on the Web of Science collection. Out of a total of 207 research publications, India and other countries contributed eight and 199 publications respectively, with a publication percentage of 3.86 and 96.13. Globally, the impact factor (JIF) ranged from 0.22 (Journal of the Kansas Entomological Society) to 10.151 (New Phytologist). Similarly for Indian publications, the range was from 0.208 to 4.223. Web of Science citation of all papers published on this topic totaled 4,302 excluding self-citation. The average h-index was 35 and the average citation per year was 245.16. If the research progress through these years is monitored, it was explicit that the research picked up during the last decade and around 87 percent of total publications made were from 2010 to 2021. The researchers should focus more on HIPV synthetic production and application which enhances its uses in IPM.
