摘要(Abstract)：

呋虫胺作为新一代烟碱类农药,究竟会给蜜蜂造成何种影响尚不清楚。本研究选取意大利蜜蜂为研究对象,分别测定呋虫胺对蜜蜂的急性毒性、慢性毒性以及幼虫发育毒性,并通过其危害商值(hazard quotient,HQ)初步评价呋虫胺对蜜蜂的生态风险,综合评价呋虫胺对蜜蜂的安全性。结果表明,急性经口毒性48 h半数致死剂量(48 h-LD50)为0.033μg·蜂-1,对蜜蜂高毒;慢性毒性10 d半数致死剂量(10 d-LDD50)为0.010μg·蜂-1,慢性毒作用带比值为3.5,存在慢性中毒的风险;幼虫7 d半数致死剂量为577 ng·幼虫-1,高剂量呋虫胺对蜜蜂幼虫存活率、化蛹率和羽化率均存在影响,处理剂量越高,存活率、化蛹率和羽化率越低,呈高度负相关(r=-0.98,-0.89,-0.80)。风险评价结果表明,呋虫胺对蜜蜂为中等风险到高风险。研究可为呋虫胺的合理使用提供科学参考。
