  • Environmental risk assessment of living modified (LM) crops is essential for their cultivation. In this study, we cultivated β-carotene enhanced transgenic soybean (LM soybean) and non-LM soybean (Gwangan) in living modified organism (LMO) isolated fields, and investigated changes in the insect fauna using three types of collection methods for three years. In total, 331,483 individual insects and arachnids, representing 82 families in 14 orders, were captured during the study. Totals of 166,518 and 164,965 individual insects and arachnids were collected from LM soybean and Gwangan, respectively. Throughout the study, although there were differences between the investigation year, region, and methods, there were no significant differences between the population densities of insect pests, natural enemies, and other insects on LM soybean and non-LM soybean. Also, there were no statistically significant differences between varieties in the results of the species diversity analysis. The data on insect species population densities were subjected to multidimensional scaling (MDS), which did not distinguish between the two varieties, LM soybean and the non-LM soybean, in all cultivated fields. However, the results of the MDS analysis were completely divided into six groups based on the yearly survey areas. These results provided the insect diversity for an environmental risk assessment of LM soybean and suggested that the guideline could be useful to detect LM crops.
