中文摘要：
【目的】 研究转Bt基因水稻“赣绿1号”对田间节肢动物群落的影响。【方法】 以含有转cry1Ab/Ac基因水稻与常规对照为材料，2012和2013连续两年在江西南昌县开展田间试验。【结果】 转Bt基因水稻“赣绿1号”田间节肢动物群落结构物种数、优势集中度、香农指数和均匀性指数与对照相比，均无显著差异；“赣绿1号”田间节肢动物5类功能团的优势度与对照田均无显著差异；“赣绿1号”田与对照田田间节肢动物群落相异性数值大多较低。【结论】 转Bt基因水稻“赣绿1号”对田间节肢动物群落结构没有明显的不利影响。
英文摘要：
[Objectives] The objective of this study is to assess the effects of the transgenic Bt rice “Ganlv1”on the arthropod communities in paddy fields. [Method] The rice expressing a fusion gene derived from cry1Ab and cry1Ac and a conventional control rice were investigated inNanchang County,JiangxiProvince in 2012 and 2013. [Result] No significant differences in community indices such as species richness, dominance index, Shannon-Wiener diversity index and evenness index in the transgenic Bt rice plots compared with the control rice plots . Moreover, there were no significant differences in the five guilds dominance in the transgenic Bt rice plots and the control rice plots. Mosts of the dissimilarities between the arthropod communities in the transgenic Bt rice plots and the control were apparently low. [Conclusion] It was apparent that the transgenic Bt rice “Ganlv1”had no significant adverse impact on the arthropod community structure under the field conditions.
