Agriculture faces significant environmental and health risks due to rapid and unlawful use of toxic chemical pesticides, which harm native flora and fauna, degrade soil quality, and interfere with essential biological activities, leading to fertility loss, pesticide resurgence, and global warming. Climate-smart insect pest management in agriculture, utilizing the entomopathogenic fungi has gained significant prominence as an effective non-chemical biological approach, owing to its minimal or nil toxicity issues, enhanced bioefficacy, extended shelf life, and less risk of environmental contamination. Multidimensional pest immobilization activities mediated by entomopathogenic fungi are accomplished by diverse action mechanisms of several mycotoxins and enzymes produced by this biocontrol agents, resulting in significant mycopathogenesis. In contrast to synthetic pesticides, entomopathogenic fungi do not compromise with essential soil nutrients like carbon and nitrogen, rendering them more environmentally acceptable and sustainable. In addition to its potential as a microbial biocontrol agent against major agricultural insect pests, this category of pathogenic fungus may persist for extended periods of time in adverse topography, climate, and soil. The integration of advanced technologies, including the genetic engineering, myconanoformulations, artificial intelligence, and the Internet of Things, alongside real-time data analysis and fuzzy logic, has recently revolutionized entomopathogenic research in agriculture, leading to sustainable crop protection. Additionally, bibliometrics has been an excellent tool in examining the trends, patterns, research gaps, and progress in entomopathogen-mediated plant protection in agriculture.
