摘要
为了在鱼蚌混养生产中科学使用杀虫药物提供参考数据,采用静态急性毒性法对三角帆蚌(Hyriopsis cumingii)幼蚌进行毒理学试验。5种常见药物对三角帆蚌幼蚌48hLC50、96hLC50、安全浓度(SC),草甘膦为27.46、25.62、2.56mg/L;吡喹酮为0.4491、0.1516、0.0152mg/L;甲苯咪唑为48.47、23.12、2.31mg/L;苯扎溴铵为8.749、2.977、0.298mg/L;阿维菌素为0.0137、0.00444、0.00044mg/L。从急性毒性特征分析,5种药物对三角帆蚌幼蚌的毒性高低依次为:阿维菌素>吡喹酮>苯扎溴铵>甲苯咪唑>草甘膦。
The static acute toxicity test of five kinds of drugs to Hyriopsis cumingii juveniles was determined at water temperature of （27±1）℃. The median lethal concentration （LC50） of glyphosate to H. cumingii juveniles was found 27.46 mg/L to 48 h, 25.62 mg/L to 96 h, and safe concentration （SC） of 2.56 mg/L. The LC50 of praziquante was 0.4491 mg/L to 48 h, 0.1516 mg/L to 96 h, and SC of 0.0152 mg/L. The LC50 of mebendazole was 48.47 mg/L to 48 h, 23.12 mg/L to 96 h, and SC of 2.31 mg/L. The LC50 of benzalkoniam bromide was found 8.749 mg/L to 48 h, 2.977 mg/L to 96 h, and SC of 0.298 mg/L. The LC50 of avermectin was 0.0137 mg/L to 48 h, 0.00444 mg/L to 96 h, and SC of 0.00044 mg/L. The toxicity of the above-mentioned five drugs in sequence was avermectinpraziquantebenzalkoniam bromidemebendazole glyphosate.
