Abstract：This paper studied the acute toxic effect of cypermethrin on Daphnia magna HB. D. magna HB was exposed to cypermethrin at concentrations of 0,1,3,5,7, 9 mg/L for 24 h. The resuts showed that the 24 h-LC 50 of cypermethrin on D. magna HB was 4.81 mg/L. Meanwhile, it studied the toxicity of K 2Cr 2O 7, suggesting the daphnia was very sensitive to pesticides. At last, it also discussed the influence of environmental factors (hardness, temperature and DO etc.) on 24 h-LC 50 .
