It emphasizes the integration of genetic tools such as RNA interference (RNAi) and gene editing techniques into existing Integrated Pest Management (IPM) frameworks, as well as case studies demonstrating the practical application of these tools in different regions. The study discusses challenges, including ethical considerations, regulatory barriers, and the need for public participation, and highlights the importance of international cooperation and strong policy-making. This study aims to emphasize the potential of genetic insights to revolutionize pest management and contribute to sustainable agriculture and global food security. Keywords Sitophilus oryzae; Genetic pest management; RNA interference (RNAi); Integrated Pest Management (IPM); Sustainable agriculture 1 Introduction Sitophilus oryzae, commonly known as the rice weevil, is a significant pest affecting stored grains worldwide, particularly rice (Zhang et al., 2023). This beetle is notorious for causing extensive damage to cereal crops both in the field and during storage, rendering grains unsuitable for consumption and export (Hu et al., 2018; Parisot et al., 2021). The rice weevil's ability to infest and damage stored grains makes it a major concern for food security and economic stability in regions dependent on rice as a staple food (Pal et al., 2021). Its widespread presence and adaptability have made it a persistent challenge for agricultural sectors globally (Thangaraj et al., 2016; Suhriani et al., 2023). Managing infestations of S. oryzae presents several challenges. The primary method of control has been the use of chemical fumigants like phosphine; however, the indiscriminate and prolonged use of such chemicals has led to the development of resistance in weevil populations (Selvapandian et al., 2023). Genetic studies have revealed low mitochondrial diversity in S. oryzae, which may be linked to repeated fumigation practices that eliminate less common haplotypes, complicating resistance management strategies (Thangaraj et al., 2019). Additionally, resistance to other insecticides, such as deltamethrin, has been documented, further complicating control efforts (Singh et al., 2021). The genetic variability and adaptability of S. oryzae across different geographic regions also pose significant hurdles in implementing uniform pest management strategies (Fahad et al., 2018). By sequencing the genome and analyzing genetic markers, this study revealed the molecular basis of resistance and adaptability in Aspergillus oryzae, explored the interaction between hosts and symbionts, and explored the role of transposons in the elephant beetle genome. This may provide new approaches for pest control strategies, promote the development of more effective and sustainable pest management practices, reduce dependence on chemical fumigants, and alleviate the economic impact of rice blast disease on rice production. This study aims to provide comprehensive genetic insights into S. oryzae, focusing on its genome structure, genetic diversity, and resistance mechanisms.
