| Abstract: |
| In order to assess the effects of transgenic maize(HGK60)with Cry1Ah and non-transgenic maize(Zheng 58)on biodiversity, insect community, nematode community, and field insect pests, a five-point sampling method, pitfall traps, and direct observation were used. The results showed that compared with the non-transgenic maize ‘Zheng 58’ as control, in HGK60, the insect communities sampled showed no significant difference in abundance and structure(P>0.05). Compared with the non-transgenic maize ‘Zheng 58’, HGK60 showed obvious resistance to borer pests. HGK60 showed no significant effect on the structure of the nematode community in soil(P>0.05). Our results indicate that the transgenic insect-resistant maize HGK60 is resistance to insect pests but showed negative non-significant effects on the diversity of insect and nematode communities. |
