| Abstract: | 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. |
