| 中文摘要: |
| 为探讨转基因玉米对生物多样性的影响，本研究以转基因抗虫玉米（HGK60）（Bt Cry1Ah）及对照常规玉米（郑58）为研究对象，采用五点取样法、直接观察法、陷阱调查法进行转基因抗虫玉米田间昆虫群落、线虫群落调查和田间虫害的影响研究。结果表明：与亲本郑58相比，HGK60对田间昆虫的数量和群落结构没有显著影响（P>0.05）。转基因玉米HGK60与对应的非转基因对照郑58相比，对钻蛀类害虫具有明显抗性。HGK60对土壤中线虫群落结构无显著影响（P>0.05）。研究表明转基因抗虫玉米HGK60的种植对虫害具有抗性作用，对田间昆虫和线虫无显著影响。 |
| 英文摘要: |
| 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. |
