Abstract： Since 1996，Bt ( Bacillus thuringiensis) cotton has been increasing adopted worldwide，mainly including the United States，Australia，China，India and Pakistan，and the planting proportion of Bt cotton recently amounted to about 60% of the total area of all cotton crops． Vast studies indicate that widespread adoption of Bt cotton effectively suppressed the population of various target insect pests，and then lessened the amount of insecticide use in this crop; but less insecticide application also caused the outbreak of many non-target insect pests． In order to solve the new pest problem in Bt cotton，various measures of cultural control，biological control，chemical control and others have been developed and applied in the major Bt-cotton growing countries．
