ABSTRACT

The field study was undertaken to examine the potential for adverse effects of transgenic soybean expressing bioactive human epidermal growth factor (with tolerance to the herbicide glufosinate, PPT) on the abundance and diversity of plant‐dwelling arthropods by comparing with those of a non‐GM parental cultivar, Gwangan soybean. Field surveys of soybean fields were carried out over two consecutive years, 2016 and 2017 at Ochang and Jeonju, Korea. The number of captured individuals associated with either of EGF and Gwangan soybean plants increased in 2017 compared with 2016 in both Ochang and Jeonju. During the survey period, the diversity and richness of the occurred insects and arachnids increased, dominance decreased, and the evenness of the insects remained static. The insects of Hymenoptera Order occurred most often comprised 25.4% of total captured insect pests. On the contrary, natural enemy from Hymenoptera Order and other insects from Diptera Order occurred more frequently (29.9% and 19.0%, respectively) in both the survey regions during the study periods. The score from PROXSCAL multidimensional scaling using combined data showed that the occurrence of insects and arachnids were separated due to their cultivation regions and years, irrespective of soybean cultivars. Consequently, the results indicated that there happened no notable change in the composition of arthropod communities in soybean agroecosystem due to GM event in soybean expressing EGF.

进行实地研究的目的是通过与非转基因大豆进行比较，研究表达生物活性人表皮生长因子（对除草剂草铵膦，PPT具有耐受性）的转基因大豆对植物节肢动物的丰度和多样性的潜在不利影响。亲本品种，广安大豆。 2016年和2017年连续两年在韩国梧仓和全州进行了大豆田实地调查。与 2016 年相比，2017 年在梧仓和全州捕获的与 EGF 和广安大豆植物相关的个体数量均有所增加。调查期间，昆虫和蜘蛛类发生的多样性和丰富度上升，优势度下降，昆虫均匀度保持不变。发生最多的膜翅目昆虫占捕获害虫总量的25.4%。相反，膜翅目天敌和双翅目其他昆虫在研究期间在两个调查区出现的频率较高（分别为29.9%和19.0%）。使用组合数据的 PROXSCAL 多维标度评分表明，昆虫和蜘蛛的出现因其种植地区和年份而有所不同，与大豆品种无关。因此，结果表明，表达EGF的大豆中的转基因事件并未导致大豆农业生态系统中节肢动物群落的组成发生显着变化。
