Abstract: In order to investigate the effects of transgenic rice H23 resistant to BPH and herbicide on the safety of non-target organisms,Chilo suppressalis,Daphnia magna Straus and Eisenia foetida were studied as environmental bio-indicators. The survival and weight of Chilo suppressalis were examined on the 6th day after inoculation at tillering and jointing stage. Under indoor conditions,the survival rate and reproduction number of Daphnia magna were investigated by feeding H23 rice powder. Survival, weight and behavior of the Eisenia foetida, which was fed with transgenic rice straw in artificial soil for 28 days, were investigated. Non-transgenic rice Guangzhan 63-4S was used as a control in these trails. The results showed that H23 had no significant effect on the growth of both organisms,as compared with that of the nontransgenic control.Thus,we concluded that the transgenic rice H23 did not pose an ecological risk to Chilo suppressalis,Daphnia magna Straus and Eisenia foetida following short-term exposure.
