Entomopathogenic fungi, often acknowledged primarily for their insecticidal properties, fulfill diverse roles within ecosystems. These roles encompass endophytism, antagonism against plant diseases, promotion of the growth of plants, and inhabitation of the rhizosphere, occurring both naturally and upon artificial inoculation, as substantiated by a growing body of contemporary research. Numerous studies have highlighted the beneficial aspects of endophytic colonization. This review aims to systematically organize information concerning the direct (nutrient acquisition and production of phytohormones) and indirect (resistance induction, antibiotic and secondary metabolite production, siderophore production, and mitigation of abiotic and biotic stresses) implications of endophytic colonization. Furthermore, a thorough discussion of these mechanisms is provided. Several challenges, including isolation complexities, classification of novel strains, and the impact of terrestrial location, vegetation type, and anthropogenic reluctance to use fungal entomopathogens, have been recognized as hurdles. However, recent advancements in biotechnology within microbial research hold promising solutions to many of these challenges. Ultimately, the current constraints delineate potential future avenues for leveraging endophytic fungal entomopathogens as dual microbial control agents.
昆虫病原真菌通常主要因其杀虫特性而为人所知，它们在生态系统中发挥着多种作用。这些作用包括内生性、对植物病害的拮抗作用、促进植物生长以及在根际定殖，无论是自然发生还是人工接种后都会出现，越来越多的当代研究证实了这一点。许多研究都强调了内生定殖的有益方面。本综述旨在系统整理有关内生定殖的直接（养分获取和植物激素产生）和间接（抗性诱导、抗生素和次生代谢产物产生、铁载体产生以及缓解非生物和生物胁迫）影响的信息。此外，还对这些机制进行了深入讨论。一些挑战，包括分离的复杂性、新菌株的分类以及地理位置、植被类型和人为不愿使用真菌昆虫病原体的影响，已被视为障碍。然而，微生物研究中生物技术的最新进展为应对许多此类挑战提供了有希望的解决方案。最终，当前的限制因素为将内生真菌昆虫病原体用作双重微生物控制剂描绘了潜在的未来途径。
