“…Therefore, the arthropods were placed in Petri dishes over dry ice and examined using a Leica M125 stereomicroscope (Leica Microsystems S.A., Barcelona, Spain) for categorization and taxonomic identification. Collected arthropods were categorized as insect pests, natural enemies, and other insects (i.e., insects other than insect pests and natural enemies; Choi et al 2015). All the arthropods were counted and identified at the family level.…”

In order to guarantee the safety of genetically modified (GM) soybean crops, it is important to assess the potential toxicity of their expressed insecticidal proteins to non-target organisms. In the present study, the effects of the GM soybean Insulin-like Growth Factor (IGF), which is tolerant to the herbicide glufosinate, on plant-dwelling non-target insects and arachnids were evaluated in soybean agroecosystems. For comparison, the non-GM parental cultivar of soybean Gwangan-kong was used as a control. Data were collected in 2016 and 2017 via surveying at Ochang and Jeonju, Korea. In total, 13,031 individual insects and arachnids, representing 64 families in 11 orders, were captured during the study. Firstly, the results indicate that the GM soybean IGF did not negatively affect plant-dwelling non-target insects and arachnids. However, the numbers of captured individuals on both IGF and Gwangan-kong were higher at Ochang in 2017. The occurrence of insect pests, natural enemies, and other insects differed significantly according to region, region and survey year, and survey year, respectively. In addition, the dominance, diversity, evenness, and richness indices for the collected insects varied significantly among the regions and survey years regardless of soybean variety. The score from PROXSCAL multidimensional scaling using combined data showed that insects and arachnids in different natural environments were separated by their cultivation regions and years irrespective of soybean cultivars.

“…The identified arthropods were classified as pests, natural enemies, or other insects based on their behavior and function (Choi et al . 2015). After identification, pest groups were counted at the species level, while natural enemies and other groups were counted at the family level.…”

“…We compared the specimens with various illustrations and reference keys at the time of identification (An 2011;Bae 2001;Park et al 2012). The identified arthropods were classified as pests, natural enemies, or other insects based on their behavior and function (Choi et al 2015). After identification, pest groups were counted at the species level, while natural enemies and other groups were counted at the family level.…”

“…Despite the positive aspects of GM crops, many concerns such as potential toxicities and allergies, gene flow, weeds, generation of new types of toxins and viruses, disruption to ecosystems, and environmental impacts are also emerging (Oh et al 2016b). In response to these concerns, Korean studies are evaluating the safety of GM crops, with emphasis on biodiversity research through quantitative studies of species, population changes, and surrounding ecosystems (Amin et al 2020;Choi et al 2015;Kwon 2008).…”

“…Arthropod species are also associated with GM crops and play an important role in the agroecosystem, but their abundance and species diversity in GM rice ecosystems are still unknown in Korea. Safety assessment studies on GM rice in LMO quarantine fields in Korea are ongoing, but research is mainly focused on the occurrences of pest insects, mites, and spiders (Bae et al 2012;Choi et al 2015;Kim et al 2010;Oh et al 2017;Oh et al 2019) and studies are yet to investigate non-target arthropods associated with GM rice (Oh et al 2018).…”

Transgenic rice (Bt-T event) shows resistance against rice leaf roller (Cnaphalocrocis medinalis) by expressing a toxic protein (mCry1Ac1) mediated from the soil bacterium Bacillus thuringiensis. Environmental risk assessment of Bt-T event, in addition to the parent variety Dongjin-byeo and cultivar Ilmi-byeo, was performed during the rice cultivation seasons of 2016 and 2017 at LMO quarantine fields in Gunwi and Jeonju, Korea. Non-target arthropods (insects and spiders) were captured using an aspirator from the three rice ecosystems of both locations, and in total 39,734 individuals of 57 families and 11 orders were collected. The numbers of individuals collected from the Bt-T, Dongjin-byeo and Ilmi-byeo rice ecosystems were 12,899, 12,730, and 14,105, respectively, which did not differ significantly among rice ecosystems. The dominance, diversity, evenness, and richness indices of the collected insects were not statistically different among the rice ecosystems, but significant variations between the two locations and survey years were detected. Principal component analysis showed that insects and spiders in the Bt-T, Dongjinbyeo, and Ilmi-byeo rice ecosystems were separated by the study locations and years irrespective of rice variety. In conclusion, results obtained in two consecutive years from two non-genetically modified rice ecosystems and a Bt-T rice ecosystem showed that the Bt-T rice had no significant negative impacts on the above-ground insect and spider communities.
