摘　　要：The acute toxic effect of the pesticide cypermethrin to Daphnia magna HB was examined. D. magna HB was exposed to cypermethrin at concentrations of 0, 1, 3, 5, 7, and 9 mg/L for 24 h. Data showed that the 24 h-LC 50 of cypermthrin on D. magna HB was 4.81 mg/L. In contrast, the 24 h-LC 50 of K 2Cr 2O 7(the national standard toxicant) to Daphnia magna was 0.38 mg/L in the current study. Results indicated that the Daphnia magna was very sensitive to pesticides. In addition, the effects of the culture condition(such as hardness, temperature and DO etc.) on Daphnia magna HB was also studied.The acute toxic effect of the pesticide cypermethrin to Daphnia magna HB was examined.
