Now a new study from South Africa shows similar results.<\/strong><\/p>\n<p>The study is described in an article called \u201c<a href=\"http:\/\/esa.publisher.ingentaconnect.com\/content\/esa\/envent\/2014\/00000043\/00000001\/art00023\">Comparative Diversity of Arthropods on Bt Maize and Non-Bt Maize in two Different Cropping Systems in South Africa<\/a>,\u201d which appears in the February 2014 issue of Environmental Entomology.<\/p>\n<p>\u201cThe 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,\u201d the authors wrote. \u201cResults 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.\u201d<\/p>\n<p>A total of 8,771 arthropod individuals, comprising 288 morphospecies, were collected from 480 plants sampled from Bt maize and non-Bt maize fields over a two-year period. The researchers found no significant differences in abundance or diversity in detritivores, herbivores, predators, or parasitoids.<\/p>\n<p>\u201cThe results of our study indicate that arthropod diversity, even in high-input farming systems, is as high as in subsistence farming systems\u201d said Dr. Johnnie van den Berg, a professor at North-West University and one of the co-authors of the article. \u201cMore recently, surveys of arthropod and plant beta-diversity inside and adjacent to maize fields have been completed during which 30,000 arthropods and 15,000 plant individuals were surveyed along a 1,000 kilometer transect. It seems that maize field diversity is homogenized and field margins had a high beta diversity,\u201d he added.<\/p>\n<p>Environmental Entomology is published by the Entomological Society of America, the largest organization in the world serving the professional and scientific needs of entomologists and people in related disciplines.
