甲氨基阿维菌素苯甲酸盐对4种非靶生物毒性及安全性评价

Toxicity and Safety Evaluation of Emamectin Benzoate on Four Types of Non-target Organism

测定了甲氨基阿维菌素苯甲酸盐对4种有代表性的非靶生物蜜蜂、鹌鹑、斑马鱼、家蚕的急性毒性,并进行了安全性评价。试验结果表明,甲氨基阿维菌素苯甲酸盐对蜜蜂触杀LD50(48h)为0.009064μg/蜂,胃毒LC50(48h)为1.024mg/L,对雌、雄鹌鹑LC50(7d)为35.92、38.53mg/kg,对斑马鱼LC50(96h)为0.2390mg/L,对家蚕LD50(96h)为0.01109mg/kg桑叶。该农药对蜜蜂、鹌鹑、斑马鱼毒性均为高毒级,对家蚕毒性为特高毒级。此项工作为甲氨基阿维菌素苯甲酸盐的合理使用提供了科学依据。

The acute toxicities of four representative non-target organisms： bee, partridge, zebra fish and silkworm, caused by emamectin benzoate were evaluated. The result of the experiment showed that the stomach toxicity caused by emamectin benzoate for bee LC50（48 h）： 1.024 mg/L, the contact caused for bee LD50（48 h）： 0.009064 μg/bee, for male and female partridge LC50（7d）： 35.92, 38.53 mg/kg, for zebra fish LC50（96 h）： 0.2390 mg/L, for silkworm LD50（96h）： 0.01109 mg/kg. The pesticide was high-poisoning for bee, partridge, zebra fish and extreme high-poisoning for silkworm. This programmer provided scientific evidence for seasonable using emamectin benzoate.
