Abstract:

Aim: In order to investigate the effects of transgenic rice H23 with BPH9 and Bar genes resistant to brown planthopper and herbicide on the safety of non-target organisms, we used Chilo suppressalis, Daphnia magna and Eisenia foetida as environmental bio-indicators.

Methods: The survival and weight of C. suppressalis was examined on the 6th day after infestation at the tillering and jointing stage. Under indoor conditions, the survival rate and reproduction number of D. magna was investigated by feeding them H23 rice powder. We also measured the survival, weight and behavior of E. foetida after being fed with transgenic rice straw in artificial soil for 28 days. As control for these trials, we fed each species non-transgenic rice Guangzhan 63-4S.

Results: The survival and single weight of C. suppressalis, the survival rate and reproduction number of D. magna, the survival, weight and behavior of E. foetida had no significant difference between H23 and Guangzhan 63-4S. H23 had no significant effect on the growth of all three organisms, as compared with that of the nontransgenic control.

Conclusion: Transgenic rice H23 did not pose an ecological risk to C. suppressalis, D. magnaand E. foetida after short-term exposure.
