China has more than 20% of the world’s population but less than 7% of the arable land. In addition, rapid urbanization and excessive application of pesticides and fertilizers have led to loss of arable land. Against this background, China’s central government made the strategic decision to develop and apply agricultural biotechnology to increase agricultural productivity and to promote national food security and green agricultural development. With huge financial support, great progress has been made in the development of insect-resistant GE (IRGE) crops, especially cotton, rice, and corn. Recently, researchers from the State Key Laboratory for Biology of Plant Diseases and Insect Pests, IPP-CAAS published a review article titled “Insect-resistant genetically engineered crops in China: development, application, and prospects for use” in Annual Review of Entomology. The development and application of IRGE crops in China and the strategies to promote their sustainable use were systematically discussed.
In this article, the authors examine the current status of research and application of IRGE crops in China, analyze the prospects and challenges, and discuss strategies to promote the development and application of GE crop technology in China. In particular, the experiences of China in management of target pest resistance evolution to Bt cotton and control of non-target insect pests were deeply analyzed, which should provide valuable lessons in sustainable use of a wide range of Bt crops for other countries, in particular developing countries with agricultural situations similar to China. Moreover, the significance of scientific layout of IRGE crops for controlling major transboundary migratory pests was discussed, which was the first time to bring up the topic worldwide. Finally, strategies for accelerating the application of GE crops based on the issues discussed in the article, were proposed, which might also be suitable for other developing countries.
