However, fewer studies concerned the effects of transgenic corn cultivation on the soil Collembola in black soil region in China. In Jilin black soil region, a six treatments study including three corn varieties (transgenic corn, control and local variety) and two sampling locations (in rizhosphere and in between plants) were deployed to study the effect of transgenic corn cultivation and sampling location on densities, species richness and community structure of Collembola. We found that root biomass was marginally decreased in transgenic corn and control variety when compared to local variety. Collembola significantly affected by sampling location treatments. Densities and species richness of collembolans significantly decreased in "between plants" than in "rizhosphere". Densities of Collembola were impacted by corn varieties. In the whole growing season, densities of Collembola significantly decreased in control than in local variety. Collembolans in transgenic variety only slightly decreased in "jointing stage" than local variety. Collembolans adversely affected in "between plants" when compared to "in rhizosphere" in "seeding stage" but not other stages. These variations of collembolans were in lines with the trend of corn root biomass. It is indicated that Collembola variations could be caused by food resources (root biomass) but not corn varieties (transgenic, control and local).展开更多
