Identifying Effective Genes as Targets for RNA Interference in Sustainable Pest Control Strategies

RNA interference (RNAi) is a powerful genetic tool that has revolutionized pest management by enabling targeted silencing of specific insect genes. By introducing double-stranded RNA (dsRNA) to target genes, RNAi can lead to phenotypic changes, reduced fitness, or even mortality in pest species, providing an alternative to chemical insecticides chemical insecticides. However, the efficacy of RNAi is highly variable across different insect orders and target genes. RNAi could target specific genes involved in an insect’s critical biological processes, such as growth, immunity, digestion, reproduction, and metabolism. This study reviews the potential of RNAi-based pest management strategies by focusing on key genes from various insect orders based on the significance of these orders in pest management, including Hemiptera, Neuroptera, Coleoptera, Diptera, Lepidoptera, and Hymenoptera. We address the variability in RNAi efficacy across different insect species, influenced by factors such as RNA degradation, delivery challenges, and organ-specific responses to gene silencing. Specifically, genes involved in cuticle formation, molting, chitin metabolism, immune response, and nervous system function are identified as prime candidates for RNAi-mediated pest control. For example, genes like chitin synthase, chitinase, acetylcholinesterase, and sex-determining genes show significant potential in reducing pest fitness, inducing mortality, and disrupting reproduction. Overall, this research provides valuable insights into the potential of RNAi as a species-specific and environmentally sustainable approach to pest control, laying the groundwork for developing innovative pest management tools that could reduce reliance on chemical insecticides.
