        [Objectives]  The development and fecundity of Chrysopa carnea Stephens reared on Aphis gossypii Glover on transgenic Bt+CpTI cotton and its parent cotton variety were studied in order to provide theoretical support for the use of transgenic Bt cotton. [Methods]  The development, larval and pupal survival rates, eclosion rate and adult fecundity of Chrysopa carnea Stephens feeding on Aphis gossypii Glover were investigated were on both transgenic Bt+CpTI cotton and the parental cotton variety. [Results]  The results show that there was no significant difference in the development duration of larvae, pupal duration and preoviposition period, and fecundity per day and total fecundity per adult during 25 days after eclosion between the different treatments. [Conclusion]  Transgenic Bt+CpTI cotton had no negative effects on the development and fecundity of Chrysopa carnea Stephens.
