【摘要】 测定了新型杀虫剂10%联苯·噻虫胺悬浮剂对家蚕、意大利蜜蜂、蚯蚓、七星瓢虫和玉米螟赤眼蜂5种环境生物的急性毒性。结果表明，10%联苯·噻虫胺悬浮剂对家蚕96 h-LC₅₀为0.141 mg/L,毒性等级为剧毒；意大利蜜蜂急性经口和接触48 h-LD₅₀分别为0.006 59和0.066 70μg/蜂，毒性等级均为高毒；蚯蚓14 d-LC₅₀为8.99 mg/kg,毒性等级为中毒；七星瓢虫14 d-LR₅₀为0.107 g/hm²;玉米螟赤眼蜂24 h-LR₅₀为2.84×10²g/hm²。10%联苯·噻虫胺悬浮剂对家蚕、意大利蜜蜂和蚯蚓存在潜在风险。建议对制剂开展更深入的风险评估，并避免在蜜蜂等环境生物外出高峰期施用农药。更多还原

【Abstract】 The acute toxicity of a new insecticide 10% bifenthrin·clothianidin suspension concentrate（SC） to five environmental organisms including Bombyx mori, Apis mellifera L., Eisenia foetida, Coccinella septempunctata and Trichogramma ostriniae were tested. The results showed that the 96 h-LC₅₀of bifenthrin·clothianidin 10% SC to B. mori was 0.141 mg/L, indicating poisonous. The 48 h-LD₅₀（oral and contact） to A. mellifera L. were 0.006 59 and 0.066 70 μg/bee respectively, and all were of high toxicity. The 14 d-LC₅₀to E. foetida was 8.99 mg/kg, indicating medium toxicity. Moreover, the 14 d-LR₅₀ to C. septempunctata was 0.107 g/hm² and the 24 h-LR₅₀ to T. ostriniae was 2.84×10² g/hm². The results of risk assessment showed that the risk to B.mori, A.mellifera L. and E. foetida were unacceptable. It is recommended to carry out further risk assessment to the insecticide and avoid the overlap spraying time with the outgoing peak of.更多还原
