[方法]采用经口半致死毒性测定方法研究18.6%拌·福·乙酰甲悬浮种衣剂对鹌鹑、家蚕、蜜蜂、斑马鱼4种生物的急性毒性,并对其进行环境安全性评价。[结果]18.6%拌·福·乙酰甲悬浮种衣剂对鹌鹑7 d的LD50值为314(雄性)、278 mg/kg(雌性),对家蚕96 h的LD50值为40.2 mg/L,对蜜蜂48 h的LD50值为4.74 mg/L,对斑马鱼96 h的LD50值为0.783 mg/L。[结论]18.6%拌·福·乙酰甲悬浮种衣剂对鹌鹑和家蚕为中毒级。对蜜蜂为高毒级,但该药剂主要用于种子包衣,且包衣种子播种至开花期相隔时间较长,因此对蜜蜂的风险极小。对斑马鱼为高毒级,应严格避免药液流入水域对鱼类造成危害。
[Method] The acute toxicities of 18.6% Spanifactyl Acetate Suspension Seed Coating to four species of quail, silkworm, bee and zebrafish were studied by the method of oral half lethality and the environmental safety was evaluated. [Result] The LD50 value of the seed dressing with 18.6% mixed bFoxo Acetyl-CoA on quails at 7 d was 314 (male) and 278 mg / kg (female), and the LD50 value of silkworm at 96 h was 40.2 mg / L. The LD50 of bees at 48 h was 4.74 mg / L and the LD50 of zebrafish at 96 h was 0.783 mg / L. [Conclusion] The 18.6% mixed bovine acetyl acetone suspension seedling was poisoned to quails and silkworms. The bees are highly toxic, but the agent is used primarily for seed coating and the coated seed is sewn to the anthesis for a longer period of time, so the risk to bees is minimal. For zebrafish is highly toxic grade, should strictly avoid the liquid into the waters of the fish cause harm.
