[Aim] Bio-safety assessment is an important requirement during the development of genetically modified varieties. We aimed to carry out research on the influence of transgenic Bt-799 maize on the diversity of arthropod communities in Jilin Province, and provide security assurance for its planting in Jilin spring maize region.[Method] We censused the arthropod community by direct observations and by using pitfall traps. Diversity was evaluated with the Shannon-Wiener, Pielou and Simpson indices.[Result] Compared with the non-transgenic maize cv. Zheng 58, as control, the arthropod communities sampled in the transgenic cultivar showed no significant difference in diversity.[Conclusion]Growing the genetically modified maize Bt-799 in Jilin Province is not expected to cause significant negative effects on the diversity of arthropod communities.
