Abstract: The phenomena that ‘the efficacy of the Bt transgenic cotton in the early stages was high, then it would decrease thereafter’ was prevalence in the current commercialized transgenic insect-resistant cotton cultivars both in home and abroad. The changes of Bt gene and its expression at different de
