It is important to understand the effect of phytase transgenic (PT) maize on arthropod communities in natural ecosystems. In this study, a 2-year survey of arthropod community biodiversity in fields of PT maize (0 7 8) and non-genetically modified (RA119, non-GM) maize was performed using sweep-net sampling on the stems and leaves of the maize plants. The results showed that there was no significant difference in the individual number of herbivorous, predatory, neutral and parasitic groups in PT maize and non-GM maize. The species number of herbivorous group in PT maize was significantly lower than that in non-GM maize in 2013 (p < 0.05). The proportions of different arthropod groups were almost identical in the PT maize and non-GM maize in terms of both species and individual number. Moreover, there was no significant difference in the Shannon-Weiner diversity index (H'), evenness index (J), dominance index (D), richness (S), and species abundance (N) between the two types of maize. The similarity coefficient of the arthropod community suggested that the arthropod community composition of PT maize was similar to that of non-GM maize. Furthermore, PT maize had no significant effect on the relative stability of the arthropod community. These results indicated that despite the presence of a relatively minor difference in arthropod community between the PT maize and non-GM maize, the PT maize had little effect on arthropod community biodiversity.

重要的是要了解植酸酶转基因（PT）玉米对自然生态系统中节肢动物群落的影响。在这项研究中，对玉米（0-7 8）和非转基因（RA119，非转基因）玉米田中节肢动物群落生物多样性进行了为期2年的调查，方法是对玉米茎和叶进行扫网取样。玉米植物。结果表明，PT玉米和非转基因玉米的草食性，掠食性，中性和寄生虫组的个体数量没有显着差异。2013年PT玉米的草食性物种种类数量显着低于非转基因玉米（p <0.05）。就种类和个体数量而言，PT玉米和非转基因玉米中不同节肢动物的比例几乎相同。此外，Shannon-Weiner多样性指数（H'），均匀度指数（J），优势指数（D），丰富度（S）和物种丰富度（N）没有显着差异。）在两种类型的玉米之间。节肢动物群落的相似系数表明，PT玉米的节肢动物群落组成与非转基因玉米相似。此外，PT玉米对节肢动物群落的相对稳定性没有显着影响。这些结果表明，尽管PT玉米和非转基因玉米在节肢动物群落中存在相对较小的差异，但PT玉米对节肢动物群落生物多样性几乎没有影响。
