The potential effects of Bt (Bacillus thuringiensis) maize on non-target organisms must be conducted before the Bt maize is commercially planted. Folsomia candida is one of the non-target organisms of Bt maize, also as an important indicator of soil quality and environmental pollution. In this study, a 90-day F. candida feeding test were conducted to evaluate the potential effects of two Bt maize lines IE09S034 and BT799 and their non-Bt conventional isolines Zong 31 and Zheng 58. The results show that Bt maize lines had no significant effects on the survival rate, reproduction, adult body length, larval body length, and the activities of acetyl cholinesterase, catalase and superoxide dismutase on the F. candida. Namely, Bt maize had no toxic effects on the F. candida.
在商业种植 Bt（苏云金芽孢杆菌）玉米之前，必须对其对非靶标生物的潜在影响进行评估。嗜虫盲蝽是 Bt 玉米的非靶标生物之一，也是土壤质量和环境污染的重要指标。在本研究中，进行了为期 90 天的 F. candida 喂养试验，以评估两种 Bt 玉米品系 IE09S034 和 BT799 及其非 Bt 常规对照系 Zong 31 和 Zheng 58 对 F. candida 的潜在影响。结果表明，Bt 玉米品系对 F. candida 的存活率、繁殖率、成虫体长、幼虫体长以及乙酰胆碱酯酶、过氧化氢酶和超氧化物歧化酶的活性均无显著影响。也就是说，Bt 玉米对 F. candida 没有毒性作用。
