摘　　要：本研究通过室内生物活性测定,评价了苏云金杆菌GDX026制剂对环境生物的安全性。结果表明,8000 IU/微升苏云金杆菌悬浮剂对鸟、蜜蜂、斑马鱼、大型溞、赤眼蜂、家蚕低毒;5%苏云金杆菌?茚虫威悬浮剂对蜜蜂、家蚕、大型溞、赤眼蜂高毒,对斑马鱼中毒,对鸟低毒;2.4%甲维?苏云金杆菌悬浮剂对家蚕、大型溞剧毒,对蜜蜂、斑马鱼高毒,对赤眼蜂中毒,对鸟不存在高风险性。苏云金杆菌GDX026与化学农药复配后,对环境生物的风险性增加。This study evaluates the safety of Bacillus thuringiensis GDX026 to environmental organisms based on degrees of toxicity and division standards. The results showed that the toxic degree of Bacillus thuringiensis 8000 IU/μL SC to birds, bees, zebrafish, Daphnia, Trichogramma and silk-worm was Ib. The toxic degrees of Bacillus thuringiensis?Indoxacarb 5% SC to bees, silkworm and Daphnia magna was Ib, to zebrafish and Trichogramma was II and low toxicity to birds. The toxic degrees of Emamectinbenzoate?Bacillus thuringiensis 2.4% SC of silkworm and Daphnia magna was Ia, Ib to bees and zebrafish, II to Trichogramma and no risk to birds. Mixture of Bacillus thuringiesis GDX026 and chemical pesticides showed higher risk levels to environmental organisms compared with Bacillus thuringiesis GDX026.
