Abstract:

IE09S034 is a genetically modified corn variety with Cry1Ie insect-resistant gene and independent intellectual property rights in China. Hand-sorting and pitfall traps methods were used to investigate the effects of IE09S034 cultivation on community composition, community structure and dynamics of dominant groups of soil macrofauna in corn fields.The results showed community composition,species richness, Shannon-wiener diversity index and Pielou index and dynamics of dominant groups did not significantly been changed in IE09S034 compared to the non-transgenic corn Zong 31. It is indicated that no environmental risk of IE09S034 cultivation on soil macrofauna were found in corn filed.

Key words: Genetically modified corn, Soil macrofauna, Bt-cry1Ie gene, Community diversity
