Abstract: In order to bring the rampant occurrence of cotton pests during 1980s under control in China, the researches and demonstrations of cotton IPM techniques had been ratified by the government as one of the national key research projects of the sixth and seventh five-year plans. Hundreds of plant protection experts from research institutes and universities of different provinces were engaged in this research project for more than five years, and a series of important achievements were obtained. In 1998, the total research project had won the Second Class Prize of national Progress of Science and Technology Award. In this paper, the main substances and ecological/social benefits of this achievements, the serious outbreak of cotton pests in 1990s, the remarkable success of commercial cultivation of Bt transgenic cotton against cotton bollworm, the progress in transgenic cotton against Verticillium wilt disease of cotton, and the recent occurrence characteristics and control strategies of cotton pests in China were reviewed and approached.
