Studies on Acute Toxicity of Fipronil to Caridina Denticulata

采用常温静水实验法进行了5%锐劲特悬乳剂对锯齿米虾的急性毒性试验。结果表明:锐劲特对锯齿米虾24h、48h、96h的半致死浓度(LC50)分别为:32.36μg/L、17.38μg/L、10.23μg/L。

The acute toxicity of 5% fipronil （regent） SC on caridina denticulate was determined by conventional method.The results showed that fipronil semi-lethal mass concentrations on Caridina denticulata in 24 h,48 h,96 h were 32.36,17.38,10.23mg/L respectively.
