摘　　要：采用静水实验法在p H值为8.2±0.1、水温(25±2)℃,溶解氧大于5 mg/L条件下,以5日龄大鳞副泥鳅(Paramisgurnus dabryanus)仔鱼和多刺裸腹溞(Moina macrocopa)为材料,研究了敌百虫和溴氰菊酯2种常用药物对大鳞副泥鳅仔鱼和多刺裸腹溞的急性毒性。结果显示:敌百虫对5日龄大鳞副泥鳅仔鱼和多刺裸腹溞的安全浓度分别为0.400 0 mg/L、0.048 9 mg/L;溴氰菊酯对大鳞副泥鳅仔鱼和多刺裸腹溞的安全浓度分别为0.160 0μg/L、0.004 2μg/L。结果表明,敌百虫急性毒性要显著性强于溴氰菊酯。The acute toxicity of dipterex and deltamethrin on 5 dph（ days after hatching） laval Paramisgurnus dabryanus and Moina macrocopa was determined in static bioassay tests,when p H was 8. 2 ± 0. 1,water temperature was（ 25 ± 2） ℃and dissolved oxygen was below 5 mg / L. The results showed that, the safe concentration of dipterex for 5 dph laval P. dabryanus and M. macrocopa were 0. 4 mg / L and 0. 0489 mg / L respectively and that the safe concentration of deltamethrin for 5 dph laval P. dabryanus and M. macrocopa were 0. 16 μg / L and 0. 0042 μg / L,respectively. The toxicities of these drugs was in order of Dipterex〉 Deltamethrin.
