甲氨基阿维菌素苯甲酸盐是一种新型的抗生素类杀虫剂、杀螨剂，其大量使用可能会导致一系列的生态风险，因此有必要开展其对相关环境生物毒性的研究。测定了甲氨基阿维菌素苯甲酸盐对意大利蜜蜂、日本鹌鹑、斑马鱼、家蚕、大型溞和赤子爱胜蚓6种非靶标生物的急性毒性。5％甲氨基阿维菌素苯甲酸盐微乳剂对蜜蜂的急性经口LC50（48 h）为0．555 a．i．mg? L-1，对鹌鹑的经口LD50（7 d）为148．369 a．i．mg? kg-1，对斑马鱼的LC50（96 h）为0．368 a．i．mg? L-1，对家蚕的急性摄入毒性LC50（96 h）为0．005 a．i．mg? L-1，对大型溞的运动抑制毒性EC50（48 h）为0．020 a．i． mg? L-1，对蚯蚓的急性毒性LC50（14 d）为18．397 a．i．mg? kg-1。该农药对家蚕和大型溞均为剧毒，对蜜蜂和斑马鱼均为高毒，对鹌鹑中毒，对蚯蚓低毒。总体而言，甲氨基阿维菌素苯甲酸盐微乳剂对环境生物危害大，在使用过程中要注意。

Background Emamectin benzoate is a novel antibiotic insecticide and acaricide .Its extensive use may lead to serious ecological risks .It is necessary to evaluate its biological toxicity in relation to untargeted species .[Method]The acute toxicity of 5% emamectin benzoate on six representative untargeted species , i.e.honeybee ( Apis mellifera) , Japanese quail ( Coturnix japoni-ca) , zebra fish ( Danio rerio) , silkworm ( Bombyx mori) , Daphnia magna and earthworm ( Eisenia fetida) , was tested in laborato-ry.[Result]The results showed that the LC50(48 h) for acute oral toxicity (microemulsion) on bee was 0.555 a.i.mg? L-1(high-ly toxic).The LD50(7 d) for quail was 148.369 a.i.mg? kg-1(moderately toxic);the LC50(96 h) for zebra fish was 0.368 a.i. mg? L-1;the LC50(96 h) for silkworm was 0.005 a.i.mg? L-1(extremely toxic), the EC50(48 h) for Daphnia magna was 0.020 a.i.mg? L-1(extremely toxic);and the LC50(14 d) for earthworm was 18.397 a.i.mg? kg-1(weakly toxic).[Conclusion and significance]In general, the emamectin benzoate can be considered of high risk to untargeted organisms and should be used with caution .
