As global agriculture faces the compounded challenges of increasing pest pressures, environmental stressors, and limited resources, enhancing the durability of genetically modified crops, particularly Bt crops, is crucial for ensuring food security and promoting sustainable agricultural development. This study analyzes gene stacking strategies aimed at enhancing the durability of Bt crops, reviews the development history of Bt crops and their significant role in pest management, and explores how gene stacking enhances crop durability through various mechanisms while effectively reducing the development of pest resistance. Through the analysis of multiple successful case studies, this study highlights the significant impact of gene stacking strategies in improving the durability of Bt crops and their clear advantages over single-trait strategies. Additionally, it discusses the technical and other challenges encountered during implementation and proposes new directions for the development of gene stacking technology to further enhance the durability of Bt crops, improve overall crop health and yield, and contribute to sustainable agricultural development.
