Previous studies from China, Spain, and the United States on genetically modified rice, cotton, and maize have concluded that the biodiversity of insects and related arthropods in GM crop fields was essentially the same as that among conventional crops. Now a new study from South Africa shows similar results.
“The aims of the study were to compile a checklist of arthropods that occur on maize in South Africa and to compare the diversity and abundance of arthropods and functional groups on Bt maize and non-Bt maize,” the authors wrote. “Results from this short-term study indicated that abundance and diversity of arthropods in maize and the different functional guilds were not significantly affected by Bt maize, either in terms of diversity or abundance.”
“[A]rthropod diversity, even in high-input farming systems, is as high as in subsistence farming systems” said Dr. Johnnie van den Berg, a professor at North-West University and one of the co-authors of the article.
