%X Entomopathogenic fungi capable of establishing mutualistic endophytic relationships with plants have a tremendous potential as biocontrol agents of insect pests. While fungi have long played an important and highly effective role in pest suppression, the utility of endophytic entomopathogenic fungi in pest management is a relatively new and emerging topic of biocontrol. Here we discuss the relevance of endophytic fungi to plant health in general, synthesize the current knowledge of the effectiveness of endophytic entomopathogenic fungi against diverse insect pests, discuss the indirect plant-mediated effects of endophytic entomopathogenic fungi on arthropods, and describe the diverse benefits of endophytic fungi to plants that are likely to affect herbivores and plant pathogens as well. Lastly, we consider major challenges to incorporating endophytic entomopathogenic fungi in biocontrol, such as their non-target effects and field efficacy, which can be variable and influenced by environmental factors. Continued research on endophyte-insect-plant-environment interactions is critical to advancing our knowledge of these fungi as a sustainable pest management tactic. © 2024 The Author(s).
