摘要
采用静态试验方法,研究了4种稻田常用杀虫剂对克氏原螯虾的急性毒性效应。试验结果表明,甲氨基阿维菌素苯甲酸盐、氯虫苯甲酰胺、茚虫威、氟啶虫酰胺对克氏原螯虾的LC_(50)(以实测浓度计)分别为3.36×10^(-2)、>1.09、5.43×10^(-3)、>96.0 mg/L。甲氨基阿维菌素苯甲酸盐和茚虫威对克氏原螯虾为剧毒,氯虫苯甲酰胺(以理论浓度计)、氟啶虫酰胺为低毒。在稻虾共作、鳖-虾-稻共作田等应避免使用甲氨基阿维菌素苯甲酸盐、茚虫威2种杀虫剂。
The acute toxic effects of four insecticides used in rice field to Procambarus clarkii were studied by static test.The results showed that the LC_(50)of emamectin benzoate,chlorantraniliprole,indoxacarb,flonicamid were 3.36×10^(-2),>1.09,5.43×10^(-3),>96.0 mg/L based on measured concentration,respectively.Emamectin benzoate and indoxacarb showed hyper toxicity to Procambarus clarkii,chlorantraniliprole showed low toxicity based on nominal concentration,and flonicamid showed low toxicity.The use of emamectin benzoate,indoxacarb should be avoided in rice-shrimp co-breeding and turtle-shrimp-rice co-breeding fields.
