%X Based on the survey in 1997, a further systematic survey was made in a transgenic Bt cotton field and two non-transgenic cotton fields (one with IPM, one with chemical control) in Nanpi county, Hebei province, in 1998. The main purposes for this research were to understand the time-space dynamics of the different functional groups in different types of cotton fields, and work out a new IPM strategy in transgenic Bt cotton fields. In an area of 0.3 hm 2 for each field, 10 plants in 10 spots were fixed for s...
