To evaluate the effect of Bt maize expressing Cry1Ie protein on non-target soil Collembola, a two-year field study was conducted in Northeast China. Bt maize line IE09S034 and its near isoline Zong 31 were selected as experimental crops; we investigated the collembolan community using both taxonomic and trait-based approaches, and elucidated the relationship between environmental variables and the collembolan community using redundancy analysis (RDA).The ANOVA results showed that maize variety neither had significant effect on the parameters based on taxonomic approach (abundance, species richness, Shannon-Wiener index, Pielou's evenness index), nor on the parameters based on trait-based approach (ocelli number, body length, pigmentation level, and furcula development) in either year. The results of RDA also showed that maize variety did not affect collembolan community significantly. These results suggest that two years cultivation of maize does not affect collembolan community in Northeast China.
为评估表达Cry1Ie蛋白的Bt玉米对非靶标土壤弹尾虫的影响，在中国东北地区进行了一项为期两年的田间研究。选择Bt玉米品系IE09S034及其近等基因系综31作为实验作物；我们使用分类学方法和基于性状的方法研究了弹尾虫群落，并使用冗余分析（RDA）阐明了环境变量与弹尾虫群落之间的关系。方差分析结果表明，玉米品种在任何一年中对基于分类学方法的参数（丰度、物种丰富度、香农-维纳指数、皮洛均匀度指数）以及基于性状的方法的参数（单眼数量、体长、色素沉着水平和叉骨发育）均无显著影响。RDA结果还表明，玉米品种对弹尾虫群落没有显著影响。这些结果表明，两年种植Bt玉米对中国东北地区的弹尾虫群落没有影响。
