This review provides a detailed exploration of its biological characteristics, including morphology, lifecycle, enzymatic properties, and the generation of secondary metabolites. Meanwhile, this review provides an in-depth analysis of its pest control mechanisms, particularly its ability to resist fungi, bacteria, and nematodes. Evaluate the effects of different formulations, concentrations, and application strategies of Aspergillus oryzae through laboratory and field application techniques. In addition, the synergistic effects of Aspergillus oryzae and other beneficial microorganisms were explored, demonstrating the potential of microbial consortia in enhancing pest control. At the same time, the advantages of Aspergillus oryzae in environmental protection, sustainability, and cost-effectiveness were also considered. This review also points out the challenges faced by the future use of Aspergillus oryzae for biological control, including its limitations, potential risks, and regulatory issues, and proposes future research directions. This review provides a theoretical framework for usingAspergillus oryzae as a pest management tool in sustainable rice cultivation. Keywords Aspergillus oryzae; Biological control; Rice pests; Pest management; Sustainable agriculture 1 Introduction Rice is a staple food for more than half of the world's population, playing a crucial role in global food security. However, rice cultivation is significantly challenged by various pests, including stem borers, leafhoppers, planthoppers, and root-knot nematodes. These pests cause extensive damage to rice crops, leading to reduced yields and compromised plant health. The economic impact is substantial, as farmers face increased costs for pest control and decreased income due to lower harvest quality and quantity. Effective pest management is essential to ensure sustainable rice production and food security (Ponce et al., 2022). Biological control involves using natural enemies, such as predators, parasitoids, and pathogens, to manage pest populations. This approach is environmentally friendly and sustainable, providing an alternative to chemical pesticides that can have adverse effects on human health and the environment. Biological control agents target specific pests, reducing the likelihood of non-target effects and resistance development. Common methods include the use of beneficial insects, nematodes, bacteria, and fungi, which act through mechanisms like predation, parasitism, competition, and the production of toxic compounds that inhibit or kill pests (Costa et al., 2021). Aspergillus oryzae is a filamentous fungus traditionally used in the fermentation industry for producing sake, soy sauce, and miso. Recently, its potential as a biological control agent has gained attention due to its ability to produce a wide range of secondary metabolites with antimicrobial properties. Research indicates that A. oryzae can inhibit the growth of various plant pathogens and pests, making it a promising candidate for integrated pest management (IPM) strategies. Its enzymatic properties and ability to thrive in diverse environmental conditions further enhance its suitability for agricultural applications (García-Conde et al., 2023). This systematic review aims to explore the role of Aspergillus oryzae in the biological control of rice pests. It will provide a comprehensive overview of the biological characteristics of A. oryzae, its mechanisms of action against
