Transgenic rice (Bt‐T event) shows resistance against rice leaf roller (Cnaphalocrocis medinalis) by expressing a toxic protein (mCry1Ac1) mediated from the soil bacterium Bacillus thuringiensis. Environmental risk assessment of Bt‐T event, in addition to the parent variety Dongjin‐byeo and cultivar Ilmi‐byeo, was performed during the rice cultivation seasons of 2016 and 2017 at LMO quarantine fields in Gunwi and Jeonju, Korea. Non‐target arthropods (insects and spiders) were captured using an aspirator from the three rice ecosystems of both locations, and in total 39,734 individuals of 57 families and 11 orders were collected. The numbers of individuals collected from the Bt‐T, Dongjin‐byeo and Ilmi‐byeo rice ecosystems were 12,899, 12,730, and 14,105, respectively, which did not differ significantly among rice ecosystems. The dominance, diversity, evenness, and richness indices of the collected insects were not statistically different among the rice ecosystems, but significant variations between the two locations and survey years were detected. Principal component analysis showed that insects and spiders in the Bt‐T, Dongjin‐byeo, and Ilmi‐byeo rice ecosystems were separated by the study locations and years irrespective of rice variety. In conclusion, results obtained in two consecutive years from two non‐genetically modified rice ecosystems and a Bt‐T rice ecosystem showed that the Bt‐T rice had no significant negative impacts on the above‐ground insect and spider communities.

抗虫转基因水稻对韩国地上非靶标节肢动物的影响

转基因水稻（Bt-T 事件）通过表达一种由土壤细菌苏云金芽孢杆菌介导的毒性蛋白 (mCry1Ac1) 显示出对水稻卷叶 (Cnaphalocrocis medinalis) 的抗性。除了亲本品种 Dongjin-byeo 和品种 Ilmi-byeo 外，Bt-T 事件的环境风险评估还在 2016 年和 2017 年的水稻种植季节在韩国军威和全州的 LMO 检疫场进行。使用吸气器从两个地点的三个水稻生态系统中捕获非目标节肢动物（昆虫和蜘蛛），总共收集了 57 个科和 11 个目 的 39,734 只个体。从 Bt-T、Dongjin-byeo 和 Ilmi-byeo 水稻生态系统中收集的个体数量分别为 12,899、12,730 和 14,105，在水稻生态系统之间没有显着差异。霸权，采集昆虫的多样性、均匀度和丰富度指数在水稻生态系统中没有统计学差异，但发现两个地点和调查年份之间存在显着差异。主成分分析表明，Bt-T、Dongjin-byeo 和 Ilmi-byeo 水稻生态系统中的昆虫和蜘蛛被研究地点和年份分开，而与水稻品种无关。总之，连续两年从两个非转基因水稻生态系统和一个 Bt-T 水稻生态系统获得的结果表明，Bt-T 水稻对地上昆虫和蜘蛛群落没有显着的负面影响。主成分分析表明，Bt-T、Dongjin-byeo 和 Ilmi-byeo 水稻生态系统中的昆虫和蜘蛛被研究地点和年份分开，而与水稻品种无关。总之，连续两年从两个非转基因水稻生态系统和一个 Bt-T 水稻生态系统获得的结果表明，Bt-T 水稻对地上昆虫和蜘蛛群落没有显着的负面影响。主成分分析表明，Bt-T、Dongjin-byeo 和 Ilmi-byeo 水稻生态系统中的昆虫和蜘蛛被研究地点和年份分开，而与水稻品种无关。总之，连续两年从两个非转基因水稻生态系统和一个 Bt-T 水稻生态系统获得的结果表明，Bt-T 水稻对地上昆虫和蜘蛛群落没有显着的负面影响。
