[Objectives]  To evaluate the ecological risk of transgenic Bt rice on soil animals. [Methods]  We fed three different varieties of transgenic Bt rice and their isogenic rice tissue residues to Folsomia candida and assessed the feeding preferences of F. candida by determining the quantity and distribution of fecal pellets associated with different Bt or non-Bt rice. [Results]  The Bt protein (Cry1Ab and Cry1Ac) of transgenic Bt rice had little impact on feeding intensity. However, inserting the Bt gene into rice plants changes the chemical composition of rice, which may affect the preferences of F. candida for plant tissue residues. These results provide a reference for the impact of transgenic Bt rice on the soil system, and provide a scientific basis for estimating the security of transgenic Bt rice.
