摘      要：[ Objective] The paper was to study the 24 and 48 h acute toxicity of common pyrethroid insecticides of eypermethrin and deltamethrin on Brachionus calyciflorus. [ Method ] With Guangzhou strain of B. colyciflorus as test animal, the standard toxicity test method was used to carry out acute toxicity test, and LC50 of cypermethrin and deltamethrin on rotifer was determined using probit method. [ Result ] LC50 of cypermethrin on rotifer was 3 376.87 and 5.87 μg/L at 24 and 48 h, respectively, and those of deltamethrin on rotifer was 594.56 and 74.17 μg/L, respectively. [Condusion] Acute toxicity of cypermethrin and dehamethrin on rotifer at 24 and 48 h was different, LC50 of cypermethrin and deltamethrin on rotifer at 48 h was more sensitive to monitor the chemical pollutants in water body than LC50 at 24 h.
