Here we report the effects of three Bt-rice varieties and their non- Bt conventional isolines on biological traits including survival, reproduction, and the activities of three antioxidant enzymes superoxide dismutase, catalase and peroxidase, in the Collembolan, Folsomia candida. The reproduction was significantly lower when fed Kemingdao and Huahui1 than those feeding on their non-GM near-isogenic varieties Xiushui and Minghui63 respectively, this can be explained by the differences of plant compositions depended on variety of rice. The catalase activity of F. candida was significantly lower when fed the Bt-rice variety Kemingdao compared to the near-isogenic non- Bt-rice variety Xiushui. This suggests that some Bt-rice varieties may impose environmental stress to collembolans. We emphasize that changes in activity of antioxidant enzymes of non-target organisms are important in understanding the ecological consequences for organisms inhabiting transgenic Bt-rice plantations. ► We examine the effects of Bt-rice on Folsomia candida with laboratory test. ► The reproduction of F. candida was decreased by two Bt-rice varieties. ► Decreased reproduction caused by the differences of varieties or C/N ratio of rice. ► The catalase activity was decreased by Bt-rice Kemingdao. ► Some Bt-rice may impose environmental stress on NTOs. The catalase of the collembolan ( Folsomia candida) was decreased when fed Bt-rice, Kemingdao.
