摘要
为了探究四氯虫酰胺对大型溞的毒性,本研究通过急性活动抑制和21 d毒性试验,研究了四氯虫酰胺对大型溞的急性毒性和繁殖毒性。结果表明,四氯虫酰胺对大型溞的急性半数活动抑制浓度EC50(48 h)为1.31×10^(-3) mg/L,表现为剧毒;经5个不同的浓度暴露21 d后,5.00×10^(-5) mg/L和1.00×10^(-4) mg/L浓度组使大型溞的首胎时长显著缩短,各处理组均对大型溞单雌总产溞数、体长、平均蜕皮次数无显著影响,而2.50×10^(-5)、5.00×10^(-5) mg/L和1.00×10^(-4) mg/L浓度处理组显著促进大型溞的单雌平均产胎数。综上所述,四氯虫酰胺对大型溞存在潜在风险。
To study the acute and reproductive toxicity of tetrachlorantraniliprole on the aquatic specials,Daphnia magna,acute immobilization test and 21 d toxicity test of tetrachlorantraniliprole to D.magna were conducted.The results showed that EC50(48 h)value of tetrachlorantraniliprole for immobilization of D.magna was 1.31×10^(-3) mg/L,and exhibited highly toxicity.After exposure to tetrachlorantraniliprole at 5 different concentrations for 21 d,the first brood time of D.magna was shifted significantly to an earlier date in 5.00×10^(-5) mg/L and 1.00×10^(-4) mg/L groups.There were no significant effects on the total number of offspring per female,body length and the average eggs of D.magna after exposed to tetrachlorantraniliprole at all tested concentrations.However,the total number of broods per female was increased significantly after exposing to tetrachlorantraniliprole at the concentrations of 2.50×10^(-5),5.00×10^(-5) mg/L and 1.00×10^(-4) mg/L.In conclusion,tetrachlorantraniliprole has potential risk to D.magna.
